Heil At a Glance
Heil has been keeping Canadian homes comfortable for a century, and today they are known for manufacturing reliable and affordable air conditioners that are built to last. They also have high-efficiency units that can save you money on your monthly energy bills, but no matter what type of Heil air conditioner you have, it’s important to care for it properly.
Doing things like changing the filter regularly, understanding common problems, knowing when you need repairs, and knowing who to call for maintenance are all important. Today we’ll tell you about all of these things and more with this Heil air conditioner repair and troubleshooting guide.
How to Replace Your Heil Air Filter
Air conditioner filters keep the air quality in your home high so that a dirty filter can lead to more dust, allergens, and pollutants in the air you breathe. Beyond that, a dirty filter will also make your cooling system less efficient, and this will cost you more money in the long run.
Finally, a dirty filter can also lead to the need for more expensive maintenance and repairs, so it’s best to change the filter every one to three months to avoid any problems. Here’s a guide to help you through the process:
- Turn off power to the unit
- Locate the filter in the return air duct or on the indoor unit
- Remove the grille from the return duct or the access panel from the unit
- Slide out the old filter
- Install a new filter using the arrows as a guide
- Replace the grille or access panel
- Turn the unit back on
What’s Wrong With Your Heil Air Conditioner?
One of the most common questions air conditioner owners ask has to do with diagnosing problems and figuring out why their cooling systems aren’t working optimally. Air conditioners have lots of components, such as fans, coils, motors, compressors, and more, and all of these can fail or get damaged, leading to problems with the system.
To help you understand and troubleshoot the most common problems, below is a description of what they are, how to recognize them, and potential solutions for some. Remember to turn your A/C completely off before opening it up to look around or attempt any fix.
Not enough airflow?
If you find your Heil air conditioner just isn’t blowing enough cool air but seems to be operating otherwise, then it could be that the filter is dirty. If the filter is dirty, you may also notice bad smells such as cooking odours or smoke that are being absorbed by the filter and recirculated through the house. To fix the problem, clean or change the filter.
Refrigerant leaks?
Refrigerant can leak from several areas, and signs of this include the unit blowing hot air, ice on the refrigerant line, temperature fluctuations, and hissing or bubbling noises coming from the unit.
Compressor or fan malfunction?
There are lots of possible causes for these problems, including worn or defective capacitors and contactors, voltage problems, wiring issues, and more. If the Heil compressor fails, it could also be that it seized because of low refrigerant.
Unit can’t keep your home cool?
This could be as simple as an incorrect thermostat setting, so first check to make sure the system is set to the right temperature. Other potential causes for this include that the unit isn’t large enough for the space you’re cooling, refrigerant levels, poor airflow, and even moisture in the system.
Leaks?
Air conditioner leaks will often occur when there’s a clog in the drain line, which causes the drain pan to fill up, overflow, and leak. The drain line will need to be unclogged because the leak can cause further damage to other system components.
System won’t run?
This will require a professional diagnosis because there are many possible causes. These include wiring problems, voltage issues, high and low-pressure controls, blown fuses, control board defects, and other defective components.
