Doing Your Part to Keep Your HVAC System Running

A few months ago, my air conditioner completely died. I woke up in the middle of the night covered in sweat, and I didn't know what to do. The next day, I called an HVAC expert, and they came out to inspect my system. It turned out that it had failed because of filthy filters and a clogged return duct, which made me sick to my stomach. I had caused the problem, and I needed to learn how to fix things. My HVAC professional taught me a few easy maintenance techniques that I didn't know before, so that I could maintain my new system.

Reasons Your Air Conditioner Isn't Chilling You Down And What An AC Service Might Need To Do


When your air conditioner isn't keeping your home cool enough, check the filter to make sure it isn't clogged. A dirty filter causes all kinds of problems with an air conditioner, and changing it could save you a repair bill.

If the filter doesn't need to be cleaned, it's time to do some detective work to see if you can pinpoint the problem. Of course, you can always call an AC service if you'd rather just get repairs done fast so you can cool down. Here are two main causes of your AC not cooling your home.

There's Not Enough Cool Air Coming Out

Check your air conditioner registers to see if the amount of air blowing out of the vents feels as strong as it usually does. The airflow should be strong. If it's weak, that gives you a clue about the problem.

A few things can decrease airflow, including a damaged air duct that lets air escape or a malfunction with the blower fan. An AC service will probably need to fix these problems, but if there is air leaking out of a duct, you might be able to do something about that if you want to try putting duct tape over the leak.

The Airflow Is Strong But Not Cool

The other main cause of an AC not keeping your home cool is that the air isn't as cold as it's supposed to be. The air blowing out of the ducts may be strong, but if it isn't cold enough your home won't cool down.

This can happen when the refrigerant gets low, there's a thermostat issue, the condenser fan is bad, the refrigerant coils are dirty or covered in ice, and airflow around the condenser and fins is blocked.

These are also issues for the AC service to repair. Refrigerant can only be handled by a licensed HVAC technician, so bringing in an AC service is necessary. The technician has to determine what's keeping the AC from making cold air so they can make the right repairs. This requires an inspection and testing of various parts.

The Repairs That Might Be Needed

In order to make more airflow, the AC technician might need to clean the blower fan, replace a bad capacitor or burned-out fan motor, or seal a leak in your ducts.

Repairs that might be needed to make cooler air include cleaning the evaporator or condenser coil, thawing ice off a coil and then cleaning it, repairing a bad condenser fan motor, repairing or replacing the thermostat, cleaning debris out of the condenser and fins, and filling leaky refrigerant after the leak hole is plugged.

To have your AC unit repaired, contact an AC service in your area.
