75% of U.S. households have some form of air conditioning. Not only will they keep you cool during the warmer months, but they’ll also improve the air quality in your home.

We’ll be going over some of the most common AC issues and how to fix them below. Keep reading to learn more!
- Your AC Unit Is Loud
It’s normal for air conditioners to produce a low hum. If the sound is louder than usual, however, there may be a problem.
For example, there may be an issue with the compressor. A malfunctioning fan motor in the outdoor condenser unit can also lead to a loud screeching noise.
The same goes for the contractor relay switch; it can cause an electrical buzzing noise if it’s not working properly. When in doubt, hire an HVAC technician—they’ll be able to identify and fix the issue.
- Your AC Is Blowing Warm Air
Refrigerant leaks can cause your AC to blow warm air. If that’s the case, you’ll want to use a sealant; it’ll react with the air and moisture to create a permanent seal.
It can also happen if you have a dirty filter. That’ll prevent the air from moving properly through the system and over time, that can cause the AC unit to overheat.
That’s why it’s so important to clean the filters on a regular basis, ideally once every 1-3 months. Just make sure that the filter is completely dry before putting it back into the unit.
- Your AC Won’t Turn On
There are several reasons why an air conditioner might not turn on. For example, there might be an issue with the thermostat. If it’s not working properly, your AC won’t know that it should be switched on.
It can also be caused by a tripped circuit breaker. Fortunately, you can fix that problem easily—just restart the breaker.
If that doesn’t work, it may be due to a capacitor issue. Depending on how old your HVAC system is, you may need to replace it altogether.
And here’s a tip for those who are planning on buying a new unit—be sure to compare quotes before making a decision. For example, you can use a site like furnaceprices.ca.
