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.

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.

The Importance of Customer Service Skills in Your HVAC Career

November 19, 2019

hvac diploma

HVAC technicians are required to have a complex skill set to address different tasks. Every day might provide different challenges, from identifying maintenance risks to diagnosing electrical and mechanical faults to cleaning a system or doing warranty service. Whether you work in a commercial or residential setting, customer service skills also play a big role in your success.

Skilled trades people trained in HVAC are in demand and many employers stress the importance of customer service skills. While it helps if you already have some experience with customers, these so-called soft skills can be learned. With practice and guidance, you will quickly see the variety of reasons these skills are important. Here are a few ideas to get you started.

Short Term Comfort Guarantees Long Term Comfort

If you work in a residential setting you know, of course, that you’re working in someone’s house. Ultimately, you are contributing to their overall comfort of their home. Installing or maintaining an air-conditioner when it’s hot or making sure a furnace runs all winter is the main job in making people feel comfortable. However, the customer’s comfort while you’re actually in their home is just as important.

When a customer is comfortable, your work will be easier

An experienced technician who has already had a long HVAC career will say that being friendly and communicative means that they get called back. A customer that feels at ease while you work is also more likely to recommend you to others, which will only help you in the long run.

Customer Trust Adds Value to HVAC Training

There are a number of ways in which you can build trust with a customer after your HVAC training. For example, it can be helpful to explain the work you are doing, give updates, and leave room for customers to ask questions. These types of exchanges add value to your work because a customer will have a better understanding of your job and see that you know what you’re talking about.

When you break down what you do in everyday language and recommend preventative maintenance it also demonstrates to a customer that your goal is to have a system that will not need extra, costly repairs. Of course, if their system does need more attention in the future, they will have confidence that your return will be worth it.

Sensitivity Gives Everyone Options

While there is a lot of joy involved in installing, repairing and maintaining the systems that people rely on every day, you sometimes have to deliver bad news. When you go out on a call because a furnace doesn’t seem to be working or the AC has stopped, your job may be to tell people they must do an expensive repair or replacement. The way a technician delivers this news must be sensitive to the situation and show understanding.

When you explain options clearly your customers are more likely to trust your recommendations

Again, communication skills come into play. Whatever the situation might be, it is important that you be able to explain a customer’s options clearly. Sensitivity to different levels of technical understanding as well as sensitivity to financial impact will keep you and your HVAC business as an option for more customers in the future.

Why Time Management is Important in an HVAC Career

October 22, 2019

hvac college

In HVAC training you will learn about fasteners, tools, codes and regulations as well as other knowledge and skills that are required for the job. However, one skill that you should not overlook is time management. If you’re looking to break into the HVAC industry, managing your time effectively can help you succeed.

Time management skills allow you to stay on track and are the best way to prepare for unexpected circumstances. Managing your time effectively also keeps you calm and reduces your stress, so that you are able to work in a focused, effective manner. Read on for more about why time management will matter in your career in the HVAC industry!

Your HVAC Career Will Be Full of Surprises

A major benefit of managing time effectively is that it helps you account for unexpected emergencies, calls and problems. In a job where you are servicing equipment and appliances, you may be called in for an issue and arrive only to discover that the problem is larger than you originally assumed it would be. This adds time to your task and delays the rest of your schedule.

If you’ve organized your day to allow for last-minute changes or service calls that run longer than expected, you’ve given yourself plenty of extra time so that you can still complete your day’s schedule. That way, if you find yourself in a situation where you need to pick up a part or change your strategy, you’ll have enough wiggle room to do so.

You never know what surprises might pop up to make a job stretch longer than usual

Time Management Helps You Save on Travel

When you are working in an HVAC career, throughout your day you may be required to travel to multiple locations that are quite dispersed. The more time you spend on the road, the less you can get done. This may cause your schedule to run behind or may not be an economical use of resources such as fuel. If you’re working with a team, failing to coordinate locations can cause unnecessary travel amongst employees.

Learning how to plan days in a way that makes sense for travel helps you manage your schedule. Establishing the most direct routes between locations is also helpful to save on time and costs, while ensuring that all of your goals for the day are accomplished.

Time Management Keeps Your Stress Levels Down After HVAC College

When tasks go unfinished or jobs are rushed, the quality of your work isn’t something you are likely to be proud of. This can cause your stress levels to rise and reduce your job satisfaction. After you have your HVAC diploma, you will want to show your skills and knowledge and perform to the best of your abilities. Making sure you have enough time and planning to finish what you’ve started helps you stay focused and healthy for a long and rewarding career. This also keeps you from constantly feeling time pressure or fearing that you won’t finish your work, which is another major stressor.

Keeping your stress levels down allows you to remain focused and effective in your career

Scheduling extra blocks in your schedule allows you to thoroughly inspect situations and consider solutions, rather than applying quick fixes that won’t last as long. Not only will this help you stay focused and calm, it will make you a more successful professional because your work will be top-notch.
