Reasons to Consider Trade School over College

by
trade-school-benefits-coynecollege

Let’s face it — the four-year education system in the United States isn’t what it used to be. Despite the best intentions of our founding fathers in establishing a land in which quality education can be achieved for all, the four-year college degree route is increasingly ineffective in preparing graduates for navigating the complexities of the real world.

Thankfully there are many alternatives available to anyone who remains passionate about investing in their education, but who also may prefer a different approach than the standard cookie-cutter model.

Among these, trade school—sometimes known as vocational training—is a mode of higher education that allows an individual to focus on developing the hands-on technical skills that are needed for a wide variety of high dignified and respectable jobs working in a more active setting (rather than a passive setting, behind a computer screen.)

There are numerous benefits to trade school, but what’s most important to note is that if your heart’s not in it, you will likely not be successful. In other words, you need to be able to be completely zoned into the trade that you will be pursuing. In other words, it’s important to focus on the Why behind your choice to enter trade school. If your only goal is to get a job, then that’s not the end of the world — but if your goal is to find a rewarding career that’s rooted in a foundation of vocational training, then you will be setting yourself up for success.

Benefits of Trade School

Get Your Degree in Less Time

One of the major benefits of trade school is that you are able to bypass the traditional schooling system, which can often end up doing a better job of indebting graduates rather than finding them rewarding jobs. By obtaining your degree in a shorter amount of time, your time is freed up to think more about the actual basis behind the work that you seek to perform throughout your career.

Improved Classroom Environments

When you attend a trade school, you won’t find yourself inside large lecture halls with hundreds of other students. In most cases, you will more commonly find yourself inside of a location that allows for more one-to-one interactions with both your instructors and the students. If you are the kind of person that learns better in that kind of an environment, then you will more likely thrive inside of a trade school setting rather than a four-year college.

Receive Hands-on Training

By earning a degree from a trade school or vocational school (rather than a four-year college), you set yourself up for success in the real world by actively exposing yourself to hands-on learning. In addition, it’s possible that you may learn some skills that apply to future jobs as well. If you are seeking to work in a job that involves working with your hands—in a way other than simply tapping a keyboard—the skills you learn in a trade school simply allow you to compound this education and experience over time.

Earn More Job Placement Opportunities

It’s a well-known fact that many graduates of four-year colleges find themselves drowning in debt and unable to find a viable job after graduation. But what’s less well known is that trade schools offer job placement opportunities that can help assuage these dynamics in a meaningful way. These opportunities are those that can be found in externships and other valuable modes of employment while still in college. Paired with the hands-on education that you receive during vocational school, the real-world benefits of attending trade schools simply cannot be beat.

Closing

If you are interested in investing in your education while still considering what the future holds for you and your career, then consider the benefits that trade school could offer. Many trade training programs exist across the country, but Coyne College in Chicago’s Loop is a particularly notable location. Coyne College’s comprehensive course offerings and commitment to learning—as well as the character of the people that end the campus—make it a highly desirable location for many aspiring trade workers to earn a high-value and inexpensive education.

Common HVAC AirFlow Issues: How to Fix them?

by
common-hvac-airflow-issues

Let’s face it: No one wants to deal with HVAC airflow issues. HVAC (short for “heating, ventilation, and air conditioning”), may seem like a topic that is easily addressable when approached through a holistic perspective of how air conditioning functions inside of a house. Unfortunately this is specialized knowledge that is mostly limited to the minds of the lucky folks who have received specialized HVAC training. But while many HVAC airflow issues can only be addressed by these professionals, some of the most common HVAC air flow problems don’t require HVAC training.

Obstructed Air Supply Registers

Supply registers are crucial components of every HVAC system that are often overlooked when diagnosing common HVAC airflow issues. Registers are essentially the decorative covers that sit on top of vents — oftentimes they feature open-and-shut venting functionality. It may seem like common sense, but sometimes these registers can be obstructed by furniture or artwork. Before you begin troubleshooting your HVAC issues, check to make sure all of your registers are open and not partially covered by anything else in your home..

Blocked Air Filtration Systems

Sometimes air filters can get clogged and lead to airflow that is drastically reduced both in terms of quality and quantity. No one wants weak, dirty, and/or potentially stinky air being blown in their direction — let alone being circulated all throughout your home or office building! In order to fix a blocked air filter, simply install a new air filter. The instructions for how to install a new air filter vary depending on the make and manufacturer, but oftentimes there are directional guides that accompany purchased air filters.

Leaking Ducts

On the opposite end of things, HVAC systems can also be inefficient. If air conditioning vents are improperly sealed or not properly connected, then this will ultimately result in less air being circulated around your home. In order to fix leaking ducts, you’ll first need to locate the origin of these leaks. Sometimes this is a task better suited to professionals, but this often depends on the size and complexity of the HVAC system. A good rule of thumb is that if you begin investigating leaking ducts but cannot identify the source of these ducts, then it is probably a good idea to call a professional who specializes in airflow issues.

Cleaning Dirty Coils

It’s important to understand that air conditioning units contain condenser coils; these coils release the heat that is removed from the rooms in our building or home. If your air conditioning unit is located outside, then these coils are exposed to weather and the elements. They can also get dirty enough that they do not release the heat. If this is the case, then you will notice that there is far less heat than is necessary to warm the home to your liking. Let’s face it: No one wants to deal with HVAC airflow issues. HVAC (short for “heating, ventilation, and air conditioning”), may seem like a topic that is easily addressable when approached through a holistic perspective of how air conditioning functions inside of a house. Unfortunately this is specialized knowledge that is mostly limited to the minds of the lucky folks who have received specialized HVAC knowledge. But while many HVAC airflow issues can only be addressed by these professionals, some of the most common HVAC air flow problems don’t require HVAC training.

Refilling Low Refrigerant

Sometimes if the air isn’t cool enough in your home, then the simple need is to refill the air conditioning system’s refrigerant. Refilling low refrigerant is something that often can be done by anyone — but first it’s worth checking with a professional to make sure you are refilling the refrigerant to the correct levels. If you are at all unsure about how to optimally refill the refrigerant needed for what your HVAC system needs, then your best bet will be to schedule at least a short ac unit consultation with your HVAC technician.

Troubleshooting Home Electrical Issues: A Quick Guide

by
troubleshoot-home-electrical-issue-coyne-college

Whether you’re a new homeowner or you’ve been dealing with homeownership issues all your life, it’s helpful to know how to troubleshoot home electrical issues. In the course of your time owning a home, you’ll inevitably end up encountering a wide variety of issues related to the electricity flowing through your house. In order to help disseminate education on these topics, we’ve created a guide featuring some of the most common issues that homeowners run into with regard to electricity and their homes.

Flickering Lights

Troubleshooting home electrical issues involves knowing how to address a wide range of electrical problems in your household. Flickering lights can indicate any number of things, but they most often result from a weakened connection between the lights and the source of electricity. These issues are important to take seriously, they can indicate the source of eventual arcing, potentially resulting in sparking, overheating, and fire. In many cases, your best bet will be to thoroughly inspect your electrical cords to ensure there are no loose or corroded connections causing the problem. In addition, be sure to check if there are any frayed electrical cords — sometimes these can be a determining factor in lighting that persists without flickering.

Frayed Electrical Cords

Sometimes flickering lights can be a symptom of frayed electrical cords. This is something that can be fixed in fairly short order, however it does require a bit of handy work to get right. If you notice frayed cords or exposed wires on any of your electrical appliances, this is a sign of unsafe wiring. Be sure to avoid using these items until they are fixed — but be on high alert, since fixing these wiring problems can also often be a highly dangerous activity. In most cases, you’re better off requesting the assistance of someone who has undergone the rigors of an electrical training program and the licensing requirements that such a profession entails (a topic we’ll return to later).

Tripped

We’ve all done it — we trip a circuit breaker because we use too much electricity from a single outlet. Thankfully, this issue is as common as the fix is straightforward: Simply locate your circuit breaker and flip the switch that has been tripped due to overuse. Remember that circuit breakers are there for your safety! In order to prevent an electrical fire or disaster, breakers close (or “break” or “trip”) the fuse switch when a homeowner has exceeded the voltage that the breaker was designed to handle. In order to prevent this from happening in the future, you’ll need to identify exactly what ultimately led the circuit to fail. Sometimes, that can entail tracing a short circuit.

Tracing a Short Circuit

Tracing a short circuit is probably the most challenging home electrical issue to troubleshoot. Because the source of a short circuit could be any number of different things, this problem is a multistep process. First, turn off all the wall switches, and then unplug every appliance from the outlets stemming from the dead circuit. Then, reset the circuit breaker and the fuse. If the circuit still goes dead right away, that could indicate that the problem lies in a short circuit in a receptacle or switch.

After resetting the circuit breaker or resetting the fuse, check to see if the circuit trips. If the new fuse does not blow immediately, you’ve likely encountered the source of the problem. The result could be that there is a short circuit in a light fixture or a receptacle controlled by the switch — or it could be that there is a short circuit in the wiring of the switch. In such instances, you’ll need to replace or repair a faulty switch, fixture or wiring; this is a task oftentimes best suited to a professional.

Finally, if turning on a wall switch does not cause a problem, then the trouble is likely to be in the lamps or appliances. In order to test each one individually, try plugging these in one at a time. Then, move some of the devices to another circuit. If the circuit still goes dead after you simply plug in a device, then you have likely identified the problem. Be sure to check the cord first, however — and consider having an appliance repair person check the appliance’s switch and other electrical parts.

Conclusion

Although electrical shortages are not uncommon in the world of home ownership, there is no shortage of content online about troubleshooting home electrical issues. At the end of the day, one needs to know enough to get the job done — and that includes staying safe. Electrical trade programs such as those offered by Chicago’s Coyne College have grown in popularity in recent years, and there is scarcely a better way to ensure the solution of your electrical needs than by employing the services of a graduate of an electrical trade program.

AC Repair and Troubleshooting Guide

by
ac-repair-troubleshooting

If it’s 90 degrees outside and humid, you undoubtedly look forward to being nice and cool in your airconditioned home. What would you do if the air conditioning suddenly went out? Would you know how to do AC repair? Take a look at this AC repair and troubleshooting guide because it could show you how to fix AC problems—and save yourself a lot of money.

Before you begin your residential air conditioner repair, you should know what the HVAC system contains and how the parts work:

  • Air return: the vents on the walls that allow air to return to be cooled
  • Exhaust outlets: similar to a stove fan, it draws out hot or humid air through ductwork, allowing fresh air to move in
  • Filter: the inexpensive cardboard-backed filter that traps contaminants like dust, pollen, and mold
  • Ducts: a network of passageways that transports air in or out, conditioning it as it flows
  • Compressor: the motor in the outdoor unit of a central AC system that circulates the refrigerant through the coils to cool your home
  • Coils: the evaporator coil (inside the house) pulls heat through the air to cool it; the condenser coil (outside) regulates the temperature of the AC’s refrigerant
  • Blower: activated by the thermostat, it engages the fan and blows the cooled air throughout the house

Common AC problems and what to do about them

Problem:

  • High energy bills
  • Limited airflow from vents
  • Ice on refrigerant lines
  • Poor cooling
  • Water leaking from AC unit

Potential fix:
Check your air filter. Does it look clogged? Covered with dirt and dust? Replace the filter. Most are cardboard frames around foam or mesh that trap the debris. A good rule of thumb is to replace it every 30 to 90 days.

Problem:

  • AC not working/won’t turn on
  • Warm or hot air (not cool) coming from vents

Potential fix:
Make sure the thermostat is on “cool” and not “heat.” Also, check the electrical panel and look for tripped circuit breakers. If the one for AC is marked “off,” then try turning it “on.”

Problem:

  • High energy bills
  • Warm air coming through vents
  • Inadequate cooling
  • Lots of repairs

Potential fix:
Check your outdoor AC unit. There could be trapped debris or dirt. Try rinsing it with a hose on a gentle setting. If there’s a thick layer of dirt on the condenser, you should call a professional.

Problem:

  • Icing on refrigerant lines
  • Blower motor issues
  • Damaged compressor
  • Frozen evaporator coil
  • Poor cooling

Potential fix:
Check the supply vents inside your house (even in the unused room) to see if they’re covered or blocked. Vents that are intentionally closed actually cause more problems and don’t save energy.

AC Repair and Troubleshooting Guide

Maintenance tips that could help your AC work efficiently

  • Check and replace air filters regularly.
  • Keep the outdoor unit free of debris and dirt and remove anything that might block the airflow.
  • Remove the condenser’s fan cage and use a wet or dry vac to clean away debris.
  • Clean the fins and straighten bent ones with a butter knife; then brush and hose the inside.
  • Clean the drain pan on the interior unit.
  • Change the blower filter every six months.
  • Dust the evaporator coil with a soft brush and spray it with no-rinse coil cleaner.
  • Clean indoor registers and air ducts with a damp cloth and vacuum away dust.
  • Listen for odd noises and see if there’s a loose bolt or debris caught in the outdoor unit.
  • Turn off the humidifier’s water supply in the summer or turn it back to 35-45 percent.
  • Give it a break when temperatures are not extreme and turn off the cooling; use the fans instead.

Just like with most things of value, if you properly maintain your HVAC system it’s probably going to work more efficiently and last longer. If you schedule regular checkups, you may be able to avoid costly air conditioner repair.

Things to Know About Commercial HVAC Systems

by
commercial-hvac-systems

Both residential and commercial HVAC systems serve the same purpose: to cool, heat, and ventilate. However, as you would expect, commercial or corporate HVAC does it on a much grander scale. They also vary in terms of mechanisms and parts.

What is an HVAC system supposed to do?

All HVAC systems strive to keep temperatures comfortable, which is generally around 72 degrees Fahrenheit. Additionally, they aim to keep indoor humidity consistent at 40-60 percent and air quality high, with CO2 less than 1,000PPM (Parts Per Million). That means that of one million gas molecules 1,000 would be carbon dioxide, and the other would be other gases.

Although there are different types of commercial HVAC systems, they all operate similarly:

  • Air conditioner units lower temperatures by expelling hot air through HVAC refrigeration or water-cooled systems.
  • Heating systems do the opposite, using water, radiator coils, or gas to heat the air.
  • Ventilation systems use fans to circulate the air and pass it through filtration systems to clean it.

How do commercial HVAC systems differ from residential systems?

Residential systems are less complicated than commercial systems and differ significantly:

  • Size: As you would expect, commercial systems are much larger than residential systems. They also have different thermostats, condenser fans, compressors, evaporators, blowers, and dampers.
  • Location: A residential HVAC system is usually placed outside the house or on the roof, in some locales. A commercial system, on the other hand, maybe located in a building’s swamp cooler or on the roof. The latter is a great space saver, which also makes for better noise control and easier access for maintenance.
  • Drainage: An individual AC unit may just have one drain or drain tray, but a commercial system has many pipes and drains to collect condensation.
  • Mechanism: This depends on both the structure and location. A residential HVAC system is usually a standalone unit, but commercial systems are generally modular. The parts in a commercial system are located in one spot, making it easier to upgrade or replace them.
  • Equipment: A commercial system is often massive and customized for the most efficient and heating for the size of the building and its use.
  • Costs and maintenance: Commercial HVAC systems are much more expensive because of their complexity, and they should be installed, serviced, and maintained only by experienced commercial HVAC contractors and technicians.

What are the different categories of commercial HVAC systems?

Building size can often determine what type or combination of HVAC system works best to heat and cool it. Although there are variations, most can be narrowed down to three main categories:

  • Single split system: Popular and affordable, this system is often found in smaller commercial buildings and allows for individual heating and cooling control of each space. If it’s an office building with a server room for computer equipment or a restaurant, this would be ideal. This system features a combination air conditioner/furnace that passes air through refrigerant lines and circulates it via air ducts. However, for each space you want to control, it requires a separate outdoor unit.
  • Multi-split system: Up to nine indoor units can connect to one outdoor unit, resulting in better energy efficiency and a smaller outdoor footprint. Sensors detect temperature changes and can be adjusted as needed. However, multi-split systems take longer to install and can be more expensive.
  • VRF (Variable Refrigerant Flow) or VRV (Variant Refrigerant Volume) systems: These work best in large mixed-use buildings, such as big office buildings or hotels, where both heating and cooling of different spaces could be needed at once.
Is there an industrial HVAC installation guide?

Many business owners know they need to get a new HVAC system, but they may have little knowledge of HVAC. They might also have trouble understanding the installation quotes or equipment requirements they get from commercial heating contractors. If they follow a few guidelines, they may be more confident when choosing a contractor and/or commercial HVAC system:

  • Ask for a complete breakdown of costs. When you talk to potential contractors, have them submit price quotes that cover all aspects of installation, from start to finish.
  • Learn about the latest heating and cooling technology, system types, and manufacturers. Compare systems, costs, and benefits.
  • Remember to include the cost of ductwork in your installation budget. Ductwork and piping can add a lot to installation costs, so you need to budget for them if you can’t use existing ducts and pipes.
  • Budget for system controls, such as thermostats. Depending on your building’s size, you could need dozens—or hundreds—of thermostat control points.
  • Talk to your contractor about regular maintenance. Getting a new system installed can be costly, but not planning for regular maintenance can make it even more expensive. Ask your contractor if they guarantee their parts and labor and if they include scheduled maintenance services.
How do you become HVAC technician?

You can enroll in a Coyne College HVAC program to get hands-on instruction from industry professionals who will teach you to install, troubleshoot, and service domestic and commercial HVAC-R systems.

Do You Need to Update Your Home’s Electrical Wiring?

by
home-electrical-wiring-update

A 2019 report by the National Fire Protection Association (NFPA) states faulty wiring was the second-leading cause of residential fires in the United States between 2012-2016. That’s alarming—especially since it is preventable. It also can run up your electricity bill. Could electrical updates save your home—and keep more money in your pocket? Here are some considerations to help you decide.

When do I need to update the wiring?

Not all unsafe wiring is old; it may just be damaged, worn, cracked, or corroded. Any of these may be signs you need to update the electrical wiring in your home to ward off the likelihood of an electrical accident or fire:

• Loose connections
• Frayed cords
• Pinched, pierced or cracked wire insulation
• Overheated wires or cords
• Damaged electrical appliances
• Wiring that rodents may have chewed

Everything seems to work, so why would I update my home electrical?

Is your home more than 40 years old? There are wiring risks in older homes that could signal a need for updates. Most homes built before the 1940s used knob and tube wiring that ran along and through the building’s frame: one black charged wire and one white neutral wire. Electrical tape placed around ungrounded soldered wires formed splices and wire connections. Insulation prior to 1960 was made of rubber that was known to crumble or flake. If the insulation became worn, was incorrectly installed, or was covered with regular building insulation material, it could be dangerous and not up to NEC—National Electrical Code—standards.

Although NEC was established in 1897, it is consistently upgraded and provides the latest regulations regarding electrical wiring, overcurrent protection, grounding, and installation of equipment. Following code doesn’t always require replacement of wiring—especially if you live in a historic home. If local code allows it and your wiring needs work, you can splice the old knob and tube wiring with a new NM (non-metallic) cable if you use a junction box, which protects wire connections. Even if your house was built as late as the early 1970s you could have a safety hazard if your wiring is aluminum, rather than the standard copper. Aluminum connections can loosen and cause fires.

How do I know if my wiring is ok?

If you have no idea when your wiring was inspected, it’s a good idea to have a professional electrician check it for wear and tear. This can be especially helpful if you’ve experienced any of the following:

• Frequently blown fuses or tripped breakers
• Flickering lights
• Tingling sensations when you touch an appliance
• A burning smell that persists from an appliance or room
• Warm, sparking or discolored electrical outlets
• Two-prong (rather than three-prong grounded) outlets throughout your house

How long does the electrical wire last?

The copper wire used for electrical wiring today can last 100 years. The problem is with the protective sheathing or insulation, which can wear down a lot sooner. It’s the type of sheathing that determines how long the wiring lasts, which is usually 50 to 70 years.

Are there any other clues that I should update the electrical wiring?

If you are keeping up with technology via computers, flat-screen TVs, air conditioners, and trendy gadgets, you might not be getting enough power to run them efficiently—or effectively. Standard household power used to run on 60 amps, but today’s devices need 200 amps of power. If you don’t have it, you could cause damage to expensive equipment. Power strips and additional outlets can help, but they may not be enough to protect your equipment and could create a safety hazard.

What do I need to do before selling my house?

If you plan to put your house on the market with outdated wiring, it might not pass inspection. You would be faced with costly repairs—and you might lose potential buyers. Updating your electrical may help you get the most money from your home sale. These updates could help get you a better offer:

• Solid copper wire and adequate grounding throughout your home
• 200-amp wiring rather than 60-amp
• Grounded outlets that all accept three-prong plugs
• Multiple outlets in each room
• A circuit breaker panel rather than a bulb-style panel
• GFCIs (ground fault circuit interrupters) put in “wet” locations (bathroom, kitchen, garage, basement)

In addition, if you arrange for an electrical inspection before your house goes on the market, you may be able to prevent potential sales issues.

electrical-wiring-training-coynecollege-Chicago
My home does have issues. How much will it cost me to update the wiring?

Where you live, the size of your home, and how much needs to be done could all impact the price of updating electrical wiring. It’s not cheap and could run into the thousands of dollars for total wiring replacement. The best time to do the updates, though, would be if you’re doing a remodeling project because contractors will be around knocking walls down or accessing the wiring anyway. If you’re lucky, you may just need to add circuits and repair damaged wires, switches or panels.

How can I become an electrician?

Coyne College Chicago can provide you with the hands-on electrical training and individualized instruction you need to prepare for an in-demand career as an electrician. Enroll in the Coyne College Electrical Construction & Maintenance program, and you’ll learn about residential and industrial wiring systems, troubleshooting, and power systems analysis.

Why Should You Choose Trade School over College?

by
trade-school-over-college

Have you ever thought that you’re not cut out for the college lifestyle? Do you want to pursue a career sooner rather than later? Maybe you don’t want to spend four years of your life partying or sitting in impractical classes you don’t enjoy when you could be training for a career that you love. If so, then trade school might be a great investment for you. Trade school careers are good options for those who want to learn a solid skill – like nursing or working as an electrician or plumber – and, best of all, many of these careers are quite high-paying considering the time you put into the schooling vs. the entry-level salary you receive when you graduate. Why chose trade school over college? Here is an overview of the benefits of attending trade school and what your career options might be depending on the trade you pick.

Trade School vs. College

1. Trade School

Trade school once carried a stigma of a school that is more advanced than high school but still not quite college. If you choose trade school vs college, you’re likely looking at two years of full-time school in a practical, career-oriented line of work like electrical or HVAC technology, medical assisting, construction, or nursing. Degrees conferred at a trade school will likely be certificate programs or Associate of Arts or Associate of Science degrees.

2. College

When most people talk about going to “college”, they mean a four-year public or private institution. Degrees conferred at a four-year institution are usually a Bachelor of Science, Bachelor of Arts, or perhaps a Bachelor of Fine Arts if you study a creative subject like film, studio art, or creative writing and you create a portfolio for your senior project.

Benefits of Choosing Trade School

If you’re a millennial, you’ve probably grown up hearing from your parents that you need to “make good grades and get into college”, not “college or trade school”, but what if you are not academically inclined or you have no patience for literature, foreign language, and theory? Maybe you’ve got a gift for practical thinking, or you might have an intuitive understanding of welding or how electrical wiring works.

  1. Career Path
    Though there is much benefit to a liberal arts education, it’s not always a practical choice to attend a four-year college and major in English or Philosophy. Majors like this, unless you have a solid career plan, might leave you high and dry and scrambling for unrelated work after you graduate. The demand for essential workers such as electricians, nurses, pharmacy technicians, and plumbers are needed to help keep communities running.
  2. Apprenticeships
    If you choose a four-year college, the closest thing you might get to a modern apprenticeship is an internship, during which you might be learning the tricks of a new trade, like working at a news station or creating important spreadsheets, or you might be fetching coffee and taking notes in meetings. At a trade school, you can take advantage of genuine vocational school training. You’re learning a real-world skill, after all, and there’s no room for a nurse who doesn’t know his or her vital signs or an electrician who doesn’t understand the basics of household wiring.
  3. Lower Tuition
    Many trade schools boast affordable tuition rates. For example, in 2019-2020, the average college tuition paid was $41,426 at private college, and on the lower end, $11,260 for in-state residents at state schools. In comparison, two-year colleges and trade schools might cost you about $7,345. Combining this lower overall cost with in demand careers makes trade school a great bet – especially in these uncertain, post-COVID times.

Medical Assistant or Pharmacy Technician

These two trade school jobs are likely to provide great entry-level pay, exciting career options, and a lot of flexibility. Do you see yourself working in a pediatrician’s office? How about filling prescriptions and communicating with patients about their medication regimens at a local, family-owned pharmacy?

There are numerous options for medical assistants, who can work in the front of the office or in the back, where they might process patient histories or even take patient vitals, like heart rate and blood pressure.

Pharmacy techs have the responsibility of communicating with both pharmacists and patients to make sure their medications are correctly filled, and they can get patients’ help from a licensed pharmacist if needed.

Everything You Wanted to Know About HVAC Installation

by
hvac-installation-guide-coynecollege

An air conditioner operates by taking in warm air and pulling it over a coolant system. In an HVAC system, there is also a heating component that can be adjusted depending on whether you want your home to be cooler or warmer.

HVAC Installation Guide

The air conditioning unit is a key component of your HVAC system, especially during the summer months when the temperatures start to soar. It is important to maintain the air quality to ensure your comfort and maintain your home’s energy efficiency. If planning to update or install a new system, then this HVAC installation guide can help you select a properly sized unit, connect the air conditioner to your central heating system, determine the cost of installation, and find the best location for your AC unit.

Sizing Up the Air Conditioner

The size of the unit makes a crucial difference in terms of air quality. If the unit is too small, then the air in your home cannot be properly treated. A unit that is too big can risk undermining energy efficiency and may even shut off before the air has fully run through the system. When considering how to install an air conditioning unit, it is best to consult with a technician on everything, including matters of unit size.

The heat gain of your home also factors into the size of the unit. When inspecting your home, the technician will determine how much heat is filtered into the living space. Everything from the placement of doors and windows to the position of your home in relation to the sun affects the heat gain calculation. Knowing how much heat is regularly retained by your home will help the technician select the most energy-efficient unit for your space.

Keeping Your Home Energy Efficient

Energy efficiency is determined through the SEER, or season energy-efficiency rating, which your technician will calculate during the inspection. The rating varies depending on much electricity the air conditioner uses to operate. Higher SEER ratings mean a lower cost for you, and the technician will ensure that your HVAC system continues to maintain your home’s energy efficiency.

The Best Place for the AC Unit and Thermostat

Any AC system is liable to make some noise, so you want to consider keeping the new unit tucked away from you and your family. Try to avoid placing the unit’s outside components near any bedrooms, as this might cause some annoyance in the future. The technician will know the best place to install the unit so that you can maintain the peace and comfort of your home.

You also want to think carefully about where to install the thermostat, which allows you to set the temperature in your home and regulates the entire HVAC system. It is best to keep the thermostat indoors and away from any draftiness that could affect its readings of the overall temperature. The thermostat should also be kept away from ducts, which will direct air toward the device and likely tamper with temperature readings. To improve energy efficiency, you can install a smart thermostat that automatically adjusts the temperature reading to create optimal living conditions.

HVAC Installation Guide for Homes with Central Heating

If you have a central heating unit already in place, a technician only needs to make a few modifications to your system. There should already be a duct system that connects to your furnace or central heating system, and the air conditioner simply needs to be introduced to this ductwork. It is important to have a technician check to make sure that the ducts are properly connected. Otherwise, the system could possibly leak and reduce energy efficiency.

Even with existing ductwork, you might need to make some changes to your system to make sure that the new unit can properly function in relation to the heating system. Possible alterations include having your furnace or heating system altered to accommodate the introduction of the air conditioner and modifying the duct system so that quality air is spread effectively and efficiently through your home.

central-hvac-heating-installation-guide
Installing New Ductwork

No HVAC installation guide would be complete without addressing what do if your house needs an entirely new duct system. Not every home has ductwork built-in, but this is not a problem for a trained technician. If your home needs to be outfitted with new ductwork, then your technician will create a floor plan and determine how to complete the installation in an unobtrusive way as possible. The best places to put ducts are spaces that are hidden from view such as closets or if you have multiple floors, attic ceilings. The technician will make sure that every aspect of your HVAC system is installed without making major renovations to your home.

The Cost of Energy Efficiency

With any new installation come cost considerations. There is not a set price for this type of renovation, and the cost of installing a new unit varies and depends on multiple factors:

  • Size of your home
  • Quality of insulation and electrical system
  • Number of doors and windows
  • Condition of ductwork

A technician will inspect your home prior to completing the air conditioning installation and can provide a cost estimate. The technician will check every element of your existing heating and cooling system to determine what is best for your home.

Warning Signs of Faulty Electrical Wiring

by
faulty-electrical-wiring-signs-coyne-college

Faulty wiring can be very dangerous. In the United States, wiring problems are responsible for tens of thousands of house fires every year. Fortunately, the majority of wiring-related accidents could be prevented by inspecting for faulty wiring and fixing it before a major issue emerges. The following faulty electrical wiring signs will help you find and address problems.

1) Visibly Damaged Wiring

It may seem obvious that any visible wire damage is a problem. However, many people overlook seemingly minor damage thinking that it won’t cause an issue. Even if the wire is mostly in good shape, it is better to fix it promptly than risk the potentially serious consequences.

Some issues to look out for include frayed wire ends. Another common problem is bite marks on the wiring. Bitten wires often look fine other than some cosmetic damage. However, sharp teeth can often sink a lot deeper than you may expect. If you find a home pest problem, consider checking the nearby wiring carefully for any damage.

2) Scorching or Discoloration

Look at outlet points around the property. Any strange colors, scorching or other evidence of burning indicate that there are some electrical problems.

Typically, this means that the wiring connected to the outlet is getting overly hot. You may also notice distortion of the faceplate of the outlet. Similarly, if you can feel heat coming from the outlet, that is a clear indication that it is heating up.

It probably comes as no surprise that hot electrical wiring is a bad thing. While it is normal for wiring to get slightly warm when used consistently, it should not be so hot that it is uncomfortable or that it causes any damage to the outlet plate. Stop using the outlet immediately and try to find the problem.

3) Frequent Blown Fuses/Breaker

If the fuse keeps blowing or the breaker keeps tripping on a circuit, that is a sign that something isn’t right. It could simply be an indication that you are overloading the circuit. However, good wiring should make this relatively difficult to do under normal operation. So, it could be a sign that there is a wiring problem.

In a well-wired property, using every outlet on a circuit should only be an issue if you are using an appliance or other item that has very high power demands. Typically, appliances such as dryers and HVAC are wired on special circuits to accommodate this demand.

Another reason you may be causing the breaker to trip is that there are too many multi-outlet extension cords on the same circuit. Again, this won’t usually be a problem unless you are egregiously overloading the circuit. If there are no obvious excess demands, there may be an issue with the circuit.

4) Excessively Messy Wiring

Electricians don’t need to make their wiring completely neat when they install it. There are no technical benefits to organized wiring nor drawbacks to messy wires. So, a little disorder isn’t necessarily anything to worry about.

However, the organization of the wires speaks somewhat to the quality of the work. Someone who is meticulous about keeping things orderly is more likely to be careful with the wiring. Conversely, an excessive mess may indicate a slapdash job. This is not a hard and fast rule, but it can be an indicator.

5) Unusual Sounds

Another one of the most important faulty electrical wiring signs is sound. In particular, buzzing is an indication that something is amiss. Normally, an electrical current should produce no noise that is audible to the human ear. However, when a wire is damaged, a prong is loose or some other issue exists, the current may jump and creating a buzzing noise.

You may also be able to hear your lights flickering even if you can’t see the problem. This indicates that the current isn’t quite flowing smoothly. Even minor issues can cause undue stress on the system and may result in a bigger problem down the road.

6) Burning or Other Unusual Odors

Similarly, strange smells are an indication that you may have electrical problems. The most common odor that you can expect is a burning smell. It is probably not a surprise that this should be investigated and resolved quickly. After all, the most common danger of wiring problems is electrical fires.

Any source of burning smell or smoke should be fixed quickly. However, if the problem is significant enough that there is clear burning on the sheathing, you should disconnect everything from the circuit and manually trip the breaker. The problem is severe enough that it could cause imminent danger.

Other odd smells should also be investigated. They could be the result of burning producing an unfamiliar smell. They could also have other causes. Regardless, it is best not to ignore anything that seems out of the ordinary.

7) Flickering or Dimming Lights

Light fixtures should only require a relatively small amount of power to run at full brightness. Therefore, if your lights are flickering or dim, it could be a sign that there is some faulty wiring.
The problem could also be that the lights are sharing an outlet with a major power consumer. Appliances that have heating or cooling elements tend to be the most electricity-hungry. Consider unplugging any appliances on the same circuit to see if that resolves the problem.

You could look into moving the lights to another circuit. Additionally, if removing the appliance from the light circuit does not fix the problem, try changing the bulbs and/or plugging in a different light fixture. If none of these changes resolve the issue, you may have a deeper problem.

Take the First Step Toward a Career as an Electrician

The above faulty electrical wiring signs will help you identify a problem with the wiring in your home or business. If you want to learn how to fix these problems yourself, consider getting an education to become an electrician. This could be your first step towards a reliable and rewarding career.

A Brief History of HVAC

by
history-of-air-conditioning

Air conditioning is something we take for granted, but when it’s on the fritz we certainly take notice. Have you ever thought about the history of air conditioning? Who was the inventor of air conditioning?

AC history (the beginnings)

In the 1840s, long before electricity was invented, John Gorrie, a Florida doctor and inventor thought cooling might be the remedy for fighting disease and keeping people comfortable. He came up a system of interior cooling that involved transporting huge blocks of ice from frozen lakes and streams in the north to cool hospital rooms. The logistics were unreasonable, so he experimented with refrigeration and devised a machine that made ice using horsepower, wind-powered sails or steam. He was granted a patent for his ice-making machine in 1851 but never saw it come to the marketplace, as his chief financial backer died. However, his work laid the foundation for modern-day air conditioning.

When was air conditioning invented?​

Willis Carrier, who worked as an engineer at the Buffalo (NY) Forge Company, was given the task of solving a big humidity problem in a Brooklyn publishing company that made magazine pages wrinkle. He designed and patented his “Apparatus for Treating Air” that used cooling coils to either humidify the air by heating water or dehumidify by cooling water. He ran tests to perfect his technology and then built and patented an automatic control system that regulated the humidity and air temperature in textile mills. With the success of his apparatus, he realized that other kinds of businesses could benefit from temperature and humidity regulation, so he left Buffalo Forge and formed his own company—Carrier Engineering Corporation—with six other engineers. The AC invention date—1902—is credited to Carrier.

Willis-Carrier-Ac-inventor

When was the term “air conditioning first used” and how big was the first AC unit?

In 1906, Stuart Cramer, who was a textile mill engineer, was the first person to coin the term “air conditioning.” The first residential unit was installed in 1914 and needed a room of its own: it was seven feet high, six feet wide and 20 feet long. One of these early units carried a price tag of $10,000 to $50,000, which translates to $120,000 to $600,000 at today’s rate of exchange.

What other major achievements in heating/cooling history followed?

Just two years later, in 1904, organizers of the St. Louis World’s Fair used mechanical refrigeration to cool parts of the Missouri State Building that housed fair events. It was able to circulate 35,000 cubic feet of air per minute and gave the public its first glimpse of cooling used for comfort. That same year, theaters began using a modified heating/cooling system that utilized refrigeration equipment to force cool air through floor vents. The problem was that lower areas were too cold and upper areas were too hot and muggy.

When was the first furnace invented?

We’ve talked about cooling, but heating is equally important. Benjamin Franklin invented the cast iron Franklin stove in 1742, which was a predecessor of the furnace. Until 1885, most homes were heated by wood-burning fireplaces, but a riveted-steel coal furnace transported heat by natural convection via ducts from the basement furnace to upper rooms. Cast iron radiators were invented around the same time and enabled homeowners to heat their homes with a coal-fired boiler that could deliver hot water or steam heat to radiators in every room. In 1935, the first forced-air furnace was introduced and used an electric fan to distribute coal-heated air through the home’s ducts; gas- and oil-fired versions followed.

How else did Carrier influence HVAC history?

Carrier’s company installed the first well-designed cooling system for theaters in Los Angeles in 1922. Air was pumped through higher vents, which resulted in more equally distributed cooling. On Memorial Day in 1925, Carrier introduced a centrifugal chilling system at New York’s Rivoli Theater: a breakthrough in HVAC inventions. Although it was more reliable and less costly than previous systems, it was still too big and expensive to use wide scale.

Was Carrier the only name associated with air conditioning?

Frigidaire and General Electric both appeared on the HVAC (heating, ventilation and air conditioning) scene within a decade of Carrier’s big achievement. In 1929, Frigidaire debuted a split-system room cooler that was shaped like a radio cabinet. Although it was small enough for homes, it was but too heavy required its own condenser. A year later, General Electric patented 32 prototypes for improved self-contained room coolers. In 1931, H.H. Schultz and J.Q. Sherman invented the first room air conditioner; it sat on a window ledge, similar to portable units today. Around the same time, General Motors synthesized CFC (chlorofluorocarbon) coolants, the world’s first non-flammable refrigerants. Although they helped with cooling, CFC coolants were later linked to ozone depletion and phased out in the 1990s.

What’s the story of the modern air conditioners we’re familiar with?

Since 1947, AC units became more compact and cheaper. In that year, 43,000 systems were in use. By the 1960s, most new homes in the United States were built with central air conditioning. By then, electric air conditioner window units were affordable and had come down in price from the early days; a 1938 Chrysler unit cost $416. By 2009, the Energy Information Administration reported that 87 percent of all American households—about 100 million homes—used AC units.
