Pursuing an HVAC Career? 5 Causes of a Leaking Air Conditioner

May 18, 2021

As summer approaches, an air conditioner becomes one of the most essential home appliances. In order to keep cool in hot temperatures, people rely on their AC unit to deliver cold air right into their homes. But what happens when this appliance starts to leak? It’s not uncommon for an air conditioner to develop such a problem over time–especially if it hasn’t been properly maintained or is being used constantly. Air conditioner leakage can occur for a variety of reasons, but the good news is that a leak can almost always be fixed. 

If you’re considering a career as an HVAC technician, knowing the most common culprits behind a leak can help you to quickly identify the source of a client’s problem: quickly restoring the flow of cool air within their homes! 

Read on to discover six common causes of air conditioner leakage. 

1. During Your HVAC Career, Be Aware That a Broken Pump May Cause a Leak

Within an air conditioner unit, the condensation pump is a device that serves to drain water in order to prevent a leak. However, this pump can actually cause a leak if it isn’t working properly. Most pumps are equipped with a float switch, which will turn on when the water gets to a certain level. If this switch has become stuck due to a buildup of debris or scum, it might not work. This lack of functioning can in turn result in dripping water from the unit. If you come across such a situation in your HVAC career, you can try cleaning the switch with bleach. If it still doesn’t turn on, chances are the pump needs replacing. 

If you’re pursuing an HVAC career, check the pump to determine whether it’s causing a leak

2. Drain Pan Issues Can Cause Leakage

Located beneath the indoor air handler, the drain pan functions as a trap for condensation created by the air conditioner. It connects to a drain pipe, which transfers the condensate outside to prevent moisture buildup around the unit. If the drain pan is rusting, cracked, or overflowing, this is likely to lead to a leak problem. Check the drain pan for leaks by turning off the AC unit and inspecting the pan for signs of rust, cracks, or debris buildup. If the drain pan is the culprit, this component of the air conditioner can easily be replaced.

3. If the Evaporator Coils Are Frozen, Leaking Will Follow

Evaporator coils can be found inside the door of the air conditioner unit. Refrigerant flows through these coils to deliver cool air through the vents. But if the evaporator coils freeze, ice will form and create a leak. These coils may freeze due to restricted air flow, a buildup of dirt or debris, blocked vents, or a lack of refrigerant. When you become an HVAC technician, you can identify frozen evaporator coils by checking whether there is ice or frost within the unit. From there, you can determine the source of the problem by checking the refrigerant levels, filter, vents, and other components to ensure that air is moving properly through the coils.

Frozen evaporator coils can lead to leakage from the AC unit

4. An Air Leak is One of the Most Common Problems

When an air leak occurs, air escapes around the vents of the air conditioner rather than through the designated path. This air flow can cause condensation to appear where it shouldn’t, leading to dripping from the AC unit. Air leaks can happen over time if a unit isn’t properly maintained. The good news is they can typically be fixed, simply with caulk, by sealing up the sides of the vent where air is escaping.

5. Look Out for a Blocked Condensation Drain Line

The condensation drain line attaches to the drain pan to transfer condensation outside–preventing leakage from occurring indoors. Over time, the drain line can accumulate debris or be exposed to algae or fungi growth. If the drip pan is overflowing but intact, it’s likely that the source of the leak is a clogged condensation drain line. Luckily, a blockage can typically be fixed by clearing the drain line using vinegar or another solution. 

These are just some of the sources of leakage in a home’s AC unit. During your HVAC career, you can refer to these common underlying issues as possible causes when it comes to developing a solution for a client’s leaking air conditioner.

3 Tips for Maintaining Propane Heating Systems After HVAC School

April 14, 2021

While propane isn’t the most commonly used source of energy for a home, its use has been growing in popularity in recent years. Propane is used to fuel both home-heating furnaces and water heaters. It is also beneficial due to the lower amount of greenhouse gas emissions it produces, as well as its potential as a less costly source of energy. In a propane heating system, propane is stored in a designated tank. This is fitted to a home’s gas line and then transferred to the furnace, which delivers heat to the rest of the home. 

Propane is a convenient source of heat for a home, but it’s important to know how to maintain a propane heating system once it’s installed to ensure that it remains safe and effective. If you’re interested in a career as an HVAC technician, read on to discover three tips for maintaining a propane heating system. 

When properly maintained, propane can be a great source of energy for a home’s heating

1. HVAC College Graduates Should Pay Attention to a Propane Heating System’s Pilot Light

Most propane heating systems operate through the use of a pilot light, which is a small flame that burns continuously. After HVAC school, it’s important to be familiar with how a propane heating system’s pilot light works in order to properly maintain these systems. In a propane heating system, the pilot light is located at the burner of the heating appliance that the propane fuel is being used for. The pilot light is also responsible for igniting the propane fuel to provide heat. 

When maintaining a propane system, check the colour of the pilot light. A pilot light’s flame should be blue in colour. But if it appears to be orange or yellow, the pilot tube may need to be cleaned. Additionally, if the pilot light frequently extinguishes, this could signal a larger problem with the propane heating system. In this case, all connections and tubes should be examined to ensure that there isn’t a leak.

2. A Propane Heating System Needs Regular Service

One of the most important things to know about propane heating systems is that they may require more regular maintenance than other heating systems. A propane tank can be regularly serviced by checking the tank’s fuel gauge. When this gauge indicates that there’s less than 20% of fuel remaining, it’s time for a refill. Additionally, it’s important to examine the tank itself regularly by checking the tightness of the connecting pipes and ensuring that there are sufficient levels of pressure. Make sure that the area around the tank is clear of any forms of clutter. If there are flammable materials in close proximity of the tank, remove them in order to reduce the risk of fire.

HVAC technicians can help to ensure that a propane tank is adequately serviced

3. Take Measures to Prevent Leakage

While a propane leak is uncommon, graduates of HVAC technician courses should be proactive in preventing leakage. A propane leak can be extremely dangerous, as propane is flammable and can increase the risk of fire within a home. The chances of a leak in a propane system can be reduced by tightening and protecting the propane tank’s fittings. Where the gas line connects to the propane tank, ensure that the connection is properly sealed by using a wrench to tighten the connection. If a leak is suspected, the main gas valve should be turned off immediately in order to safely address the problem.

When properly maintained, propane systems can be an efficient source of heat for a client’s home. During your HVAC technician career, take the above steps to ensure that your client’s propane heating system is working safely and effectively.

HVAC & The Environment: What You Should Know If You’re Pursuing an HVAC Career

March 10, 2021

Heating, ventilation and air conditioning (HVAC) systems have an essential function. They keep our homes cool in the summer and warm in the winter, in addition to regulating the quality and movement of the air that we’re breathing indoors. While HVAC systems aren’t the home appliances with the most severe environmental impact, there are still a few ways that HVAC systems can contribute negatively to the environment. HVAC systems may use refrigerants that can damage the ozone layer, and they also use electricity, the consumption of which burns fossil fuels and contributes to ozone depletion. 

While HVAC systems can cause environmental harm, there are many solutions offered today which have the potential to reduce the impact HVAC systems can have on the environment. Some of these solutions can be implemented by HVAC technicians themselves. If you’re interested in becoming an HVAC technician, here’s what you need to know about the environmental impact of these systems and the solutions available today. 

Those in an HVAC Career Should Know That HVAC Systems Can Emit Harmful Refrigerants

Air conditioning systems rely on cooling agents, or refrigerants, to drive cold air into homes, but these cooling agents have a known negative environmental impact. Hydro-chlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs) and chlorofluorocarbons (CFCs) are all refrigerants that have been reported to contribute to ozone depletion and global warming, as these compounds are greenhouse gases. In Canada, Federal Halocarbon Regulations, 2003, bans the release of halocarbons from air conditioning systems in quantities over 0.1 kg of halocarbon per 01. kg of air, but these refrigerants are still being released into the atmosphere in lower quantities. Freon (R-22), a commonly used HCFC, has been banned in Canada for use in newly manufactured HVAC systems, and Puron (R-410A), a less-harmful HFC, is now more commonly used. However, this refrigerant still contributes to direct and indirect greenhouse gas emissions.

HVAC systems emit refrigerants which contribute to ozone depletion

While it is difficult to control the emission of refrigerants into the atmosphere due to the range of HVAC systems in use today, advancements in technology have the potential to reduce their environmental impact. If you want to become a HVAC technician, you’ll probably become familiar with R-32 as a possible solution. R-32, or difluoromethane, is an HFC refrigerant known to have a lower impact on greenhouse gas emission than R-410A, and is being explored by HVAC engineers as an option to reduce the environmental impact of HVAC systems. It has been found that R-32 can even be used to make these systems more energy efficient, as it has better thermodynamic properties. In the future, developments in the use of alternative refrigerants such as R-32 have the potential to reduce the amount of greenhouse gases in the atmosphere as a result of HVAC systems.

HVAC Systems Use Energy

It’s important to be aware that HVAC systems consume high amounts of energy. Depending on the type of system and the season, an air conditioning system can consume around 3000 to 5000 watts of electricity every hour. Electricity consumption results in the burning of fossil fuels and the release of carbon dioxide into the atmosphere, a major cause of ozone layer depletion. One way to determine how much energy an air conditioning system is using is by checking its SEER rating. Older air conditioners have lower SEER ratings and tend to consume more energy.

As a way to reduce the amount of fossil fuels released, HVAC products that harness renewable energy sources are also becoming a more popular option. Renewable energy sources such as solar and geothermal energy can reduce the environmental impact of HVAC systems by using sources of power that don’t burn fossil fuels. Solar energy harnesses energy from sunlight rather than from fossil fuels to power HVAC systems, while geothermal heat pumps convert natural energy stored underground for use. 

Regular maintenance can reduce the environmental impact of HVAC systems

Small-Scale Solutions to Reduce the Environmental Impact of HVAC Systems 

The environmental impact of HVAC systems can be reduced on a small scale, and as a professional in an HVAC career, this is an area where your services are especially useful to clients looking to reduce their own personal energy consumption and greenhouse gas emissions. The efficiency of an HVAC system depends on the equipment being used. If a system’s equipment is outdated, chances are it’s using more energy or emitting a greater quantity of harmful refrigerants. Advising environmentally-conscious clients to replace old HVAC systems with an updated, energy efficient system can reduce the negative impact of older units. 

Additionally, HVAC systems should be regularly maintained in order to prevent excess emissions. Air filters should be replaced regularly, ducts and pipes should be inspected for leaks, and valves and steam traps should be examined for efficiency. 

If you want to be equipped with the ability to make HVAC systems less harmful for the environment, a program at the North American Trade Schools (NATS) could be right for you. Jason, a graduate of the North American Trade Schools HVAC technician program, says he chose NATS because of its reputation as a “hands-on school.” He notes, “They teach you what you need to know and then you apply your knowledge.” Practical, experiential training enables HVAC technicians to apply their newly learned skills in the field in innovative ways. That includes approaches that may help to reduce the environmental impact of HVAC systems.

Taking Your HVAC Diploma? Here’s What to Expect on an HVAC Unit Replacement

February 09, 2021

When you replace an old HVAC unit with a new one, there are certain things worth keeping in mind. For example, many people tend to only replace their HVAC unit on rare occasions. However, having those units replaced in regular intervals can ensure that their HVAC unit is keeping them safe, healthy, and sufficiently heated and cooled. Some homeowners may also want a new unit to help them save on energy. With the right tools and knowledge, you can complete an HVAC replacement job that accomplishes each of these things.

Although replacing an HVAC unit involves a number of steps to complete before, during, and after the installation, these are some of the more important phases to remember during this process. Read on to find out what you can expect with regards to replacing HVAC units.

Preliminary Measures for HVAC Technician Training Students to Remember

Before the replacement process can begin, there are certain tasks to take care of. For one, you’ll need to assess both the home and the old HVAC system, and complete the necessary calculations and measurements. Once this has finished, you can determine how big the new HVAC system needs to be. Measure the square footage of the home to better understand how big the new unit will need to be, and how many tons of heat it can remove. You and the client will also need to determine how they will pay for the installation. Depending on the payment plan, they may put a down payment on the replacement prior to the installation. 

Complete the necessary measurements before installing a new HVAC unit

Upon completing your cost estimate, replacing the HVAC unit can go ahead. Complete a ductwork inspection, if necessary, and disconnect the unit being replaced after powering it off. If any parts of the interior, such as furniture, are impeding your ability to get the job done, move them away from your working area. Since HVAC technician training students will learn about installing many different types of systems during their studies, it’s equally important that they learn what’s necessary for the pre-installation phase.

The Installation Process: Out With the Old, In With the New

Once these tasks have been completed, the installation of the HVAC unit replacement can begin. When installing, remember to use dust covers and wear protective gear to prevent any direct contact with debris. Even if only one component of the HVAC unit needs to be replaced, you should still replace the entire unit so that its capacity for efficiency is optimal. Be sure to also cut off power from the old HVAC unit, flush any remaining coolant, take apart the old equipment, and then remove those parts to make room for new ones. The HVAC unit replacement can often be done within the day of installation, but can sometimes go beyond that if complications arise.

If only one part needs to be replaced, it’s still worth replacing the entire system

Students in HVAC college should also familiarize themselves with the parts that will be involved in the replacement. These parts include the outside compressor, thermostats, evaporators, air handlers, condensate pumps, and/or supply lines for coolant. Once the installation process is done, remember to put the new unit through a series of tests to make sure it works correctly and can sufficiently cool the home. Inspect the system to catch any possible issues, then add a new coolant and keep testing the unit until all systems look good. Lastly, remember to discard and/or recycle any old HVAC equipment being replaced. Explain to clients how the new system works, and recommend a timeline for their next replacement.

What Those with HVAC Technician Training Should Know About the Benefits of Preventative Maintenance

September 15, 2020

hvac technician trainingThere’s nothing worse than the AC breaking down on a blazing hot day—apart from maybe the heating system fizzling out when it’s a frigid -30 degrees! HVAC technicians become very popular individuals at the height of summer and winter, serving to rescue home and business owners from uncomfortable temperatures by performing emergency repairs as they come up.

Keeping HVAC units in good working order through routine checkups is another important role of the technician. Here’s why routine maintenance practices are important for keeping these systems in their best shape all year round!

Routine Maintenance Helps Owners Breathe Easier

Respiratory problems like asthma and bronchitis can often be traced back to the living conditions of the home, with the dirty HVAC unit a prime culprit in many cases. The problem comes from condensation forming in the coils and ducts of the AC unit, which can lead to all kinds of harmful mold and bacteria growth.

Customers who keep to a routine maintenance schedule for their HVAC units are ensuring that all of the harmful contaminants that may have built up inside the system are eliminated. A service technician is responsible for cleaning filters, coils, and other components of the unit on a routine visit, which leads to a cleaner unit, thereby improving air quality.

A Well-Maintained System Can Save the Owner Money

What would a home or business owner care more about than breathing clean air? How about more money in the old pocketbook! If you’re interested in HVAC technician training, you should know that keeping an HVAC system in good working order can help the owner save money by optimizing efficiency to keep energy costs down. A well-maintained HVAC system uses a lot less energy and puts less wear and tear on the machinery of the HVAC unit, running a good 20% more efficiently than a neglected unit. 

hvac school
A well-maintained HVAC unit is much more effective at heating and cooling the home!

Regular checkups in the fall and spring can keep efficiency strong, and help an owner get a good ten years out of their HVAC investment. Routine checkups also allow the service tech to catch a small problem needing a quick, inexpensive fix before it turns into a much more complicated problem requiring lots of work—and lots of coin to repair. 

Fewer Emergency Breakdowns and More Warranty Opportunities

People run their HVAC systems pretty hard in the summer and winter months, which can lead to breakdowns. These machines are designed to handle the energy levels the owner demands, but only if the unit is being looked after properly. If you’re seeking your HVAC diploma, you should know that breakdown prevention during the hottest and coldest times of the year is reliant on keeping routine maintenance and inspection checks. 

By keeping up regular twice-a-year visits, the owner may even be lucky enough to discover that a part that needs work or full replacement is still under warranty. Longer waiting times between visits reduce the opportunity to spot a problem before a warranty period has reached its expiration date. 

What Are Some Maintenance Tasks Those Attending HVAC School Should Know About?

There are a few things to watch out for during routine maintenance checks. On heating systems, the tech will need to check: fuel lines and power sources, inspect combustion chambers, inspect the heat exchanger for cracks or other evidence of damage, as well as check for carbon monoxide leaks.

hvac diploma
A service tech will check for signs of damage or wear and tear during routine visits

On cooling systems, the tech needs to take a look at the fans and blowers, thermostat, system controls, ductwork systems, evaporator and condenser coils, and condensate drains to ensure everything is clean, undamaged, and functioning properly. Additionally, fans and motors must be lubricated, and refrigerant levels must be filled.

All of these tasks need to be performed at regular intervals to ensure that systems keep running properly.

HVAC Installation Mistakes to Avoid After HVAC Training

August 03, 2020

It’s not just the quality of an HVAC unit that counts, but how it’s installed. As an HVAC technician, your responsibility is to install these systems and detect any issues that can arise within their many different components and figure out how to correct them. However, there are several mistakes you can find yourself making if you aren’t careful with the installation process.

Since learning how to maintain and install HVAC systems are a significant component of your job, it’s just as important to know what not to do as it is to learn best installation practices. Here are some of the more common mistakes you may find yourself making after your HVAC training.

Ductwork is One of the Most Important Factors to Watch After HVAC School

It’s important to be sure you choose the correctly-sized duct for the HVAC unit you’re installing, and use high-quality materials in the process (e.g. using a heavy-duty sealant instead of tape, and adding R-6 insulation wrap).

If you don’t, it can create issues with both air flow and leaking, and potentially result in gaps, dust, loud noises, or an overheating furnace. As a result, the unit itself won’t function properly, and those living in the home will likely see their energy bills rise. Not only that, but up to 30% of the HVAC unit’s overall output can be compromised when not properly insulated.

Make sure ductwork is the correct size and not made with cheap materials

When it Comes to the Furnace, Size is Everything

By “size is also everything”, we don’t mean they need to be as big as you can possibly get them. Rather, the important thing to consider after finishing your HVAC training is to find a furnace that is sized proportionately to the one previously in place, and is also a newer model.

This not only helps with the flow of air in the home, but with the system’s efficiency as a whole. Should you not pick a correctly sized furnace, problems could occur. This includes the unit overworking itself to provide better cooling or heat if too small, or uneven temperatures if too big. However, be sure to double-check that the size calculations are correct, even if it’s technically the same size as the previous furnace.

The furnace must not be either too small or too big

Make Sure Air is Properly Distributed at All Times

This is one of the most crucial parts of a successful HVAC installation, as it can otherwise lead to uneven cooling or heating. HVAC school students should be aware that proper air distribution design is a must, and that the ductwork is symmetrical in size to the unit’s output capacity.

To achieve this, apply new ductwork rather than the preexisting one, and be sure it’s distributing air evenly. Another of the more important aspects to keep in mind is proper ventilation. You’ll need to ensure the HVAC unit you’ve installed has a strong balance of both hot and cold air, and that the air is balanced and flows cleanly throughout the home.

Tips and Tricks for a Warm Winter Home that You Can Use After HVAC College

March 31, 2020

There is no better feeling than returning to a warm and cozy house after a day outside in the snow. But how exactly do you keep a house the perfect temperature all year round?

Heating, ventilation, and air conditioning (HVAC) technicians specialize in keeping houses and the people that live in them warm in the winter and cool in the summer. Read these tips and tricks to make your customer’s home a firelit haven, sheltered from the icy elements outdoors.

Seal Any Gaps When You Become an HVAC Technician

One of the main causes of a cold house is gaps around the doors and windows that let hot air out and cool air in. When you become an HVAC technician, the first thing you should do when you get a new client is examine their home for any unsealed gaps.

They can use an acrylic-latex caulk to seal any gaps around the window frames or a spray foam that will expand into any unfilled crevices. This will also help clients to save on their energy bills, as they will need less energy to heat their homes.

If the house has a fireplace, the chimney pipe could be letting cold air in,too. When the fire is not lit,advise clients that they should close the damper. However, make sure they know to check that all embers have fully burnt out – otherwise, smoke could fill their home.

Reverse Any Fans

You might assume that fans are only useful in the hot, summer months when you need to cool down. However, fans can also keep a house warm. If you reverse the direction of the fan so it’s spinning clockwise, it will stop the hot air from rising, and push it back down to warm the room. This can be a very useful tip for many clients.

Look After The Furnace and Outdoor Unit

The majority of HVAC systems have an outdoor unit attached to the outside of the house. Even though this is built to withstand cold temperatures and heavy snow, it is still a good idea to shelter it in someway. You could build a small, temporary shelter out of wood, or use a plastic cover. This will protect the fan from freezing so that your house stays warm all winter.

At HVAC college, you may also learn the importance of checking the furnace filter. This can become dirty over time and needs to be regularly cleaned and replaced. A dirty furnace filter will not be as effective, and will mean that the house needs to use more power to generate heat.

Thermostat or Portable Heater? It Depends

Both thermostats and portable heaters have an important role to play during winter. To save energy, it’s recommended that clients program the thermostat so that it automatically turns down when they are asleep or at work. The recommended temperatures are 20 degrees Celsius in the mornings, evenings, and weekends when at home, and 10 degrees Celsius when at work, asleep, or out of the house.

If a client needs to heat up their house fast,you should advise them that turning the thermostat to max is not the answer. This will drain energy and could damage the thermostat. It also won’t be effective, because the thermostat is designed to maintain a constant temperature.

In these situations, it’s better to use a portable heater. These can generate a lot of heat from electricity in a short amount of time. However, clients need to be sure to switch them off when they are not in the room, so as not to create a health and safety risk.
