To any Canadian, one of the most important appliances that one can ever have at home is the air conditioner. Whether you’ve been living in Canada for a few years or your entire life, you’re most likely familiar with how the weather involves taking an extraordinary amount of care at home. Although the Great White North indeed has some of the lowest temperatures in the world during the winter season, it can also make for some fairly blazing months that require an AC unit to help make up for the slack.

If you’ve depended on your air conditioner to get you through the hot days, it’s best to stay on top of whatever you need to do so that it stays in great shape. However, the problem is that this can be a task that’s easier said than done because of the various bits and pieces that comprise the average unit, especially when you consider the vulnerability of its evaporator coil to go bad. 

What is an evaporator coil (and what does it do)? 

Often regarded as one of the most vital components of the cooling process, this specific component upholds an important process that air conditioners rely on to perform as expected. 

Your air conditioner’s evaporator coil is primarily concerned with aiding in the heat transfer process. Unlike many of the other parts of an AC unit’s system, this component is housed indoors near the unit’s air handler because it carries cold, liquid refrigerant that converts to a low-pressure gas within! 

How does it work?

From a technical perspective, the coil’s primary function is straightforward: it helps regulate a unit’s functioning and provides comfortable indoor temperatures when the weather is warm. Whenever your home’s air passes over, your air conditioner’s evaporator coil extracts heat from the air to lower air temperature. 

Through this process, moisture condenses so that it can dehumidify the home’s indoor air supply. Then, the moisture eventually travels from the evaporator coil to the outdoor unit, where cooled air is blown back into the home through its duct system. 

What are the signs to watch out for when it starts to go wrong?

Generally, preventing the untimely demise of your air conditioner’s evaporator coil boils down to watching out for certain signs and acting on them once they come up. If you’re not entirely sure of what to watch out for since you haven’t dealt with a broken coil before, here are some of the most common key indicators that you shouldn’t overlook:

1. You’re beginning to get warm air out of your AC unit’s vents

If you think that feeling hot air come out of your air conditioner’s vents is a bad sign, then you’re definitely correct because it means that something’s going on internally.

One of the most prominent signs that an evaporator coil is about to fail is when it starts to put out warm air from its vents which feel more like a toasty summer atmosphere. Warm air ends up steaming when the coil puts out an uncontrolled amount of hot (or evaporated) air and doesn’t condense it enough or at all—resulting in warm air instead of a cool breeze!

2. You’ve got a stubborn unit that won’t turn on

Speaking of signs, another indicator that your air conditioner’s evaporator coil is about to fail is when it doesn’t want to turn on.

Typically, your evaporator coil starts to show that it’s about to meet the end of its operational life when it starts to become resistant towards turning on (or simply doesn’t come on). If your unit doesn’t put out air at all—even if you see your lights come on and your socket’s plugged—then your AC unit’s onboard chip might be detecting a fault in your coil!
