Beat The Heat: How To Troubleshoot Common Air Conditioning Issues

Summer is here, and nothing beats the cool relief of cranking up your air conditioner. But if it fails, it can turn your home into a living hell. To avoid sweating it out, learn how to troubleshoot common AC issues. This article describes common problems and solutions to beat the heat and restore your comfort.

Poor Airflow

If you feel that the air is not moving properly, the problem may be a clogged filter. Air filters trap dust, dirt and other particles, and they need to be cleaned or replaced regularly. To fix this problem, shut off the AC unit, locate the filter and clean or replace it if needed. You can also check if the registers or vents are dirty or obstructed and clean them as well.

Refrigerant Leaks

Refrigerant is the liquid that cools the air inside your AC unit. When the refrigerant level is low, your AC won't function correctly, and you may notice that it is blowing warm air instead of cold air. If you suspect that you have a refrigerant leak, it's best to call a professional. They'll locate the leak, repair it and recharge your AC system with refrigerant.

Electrical Issues

AC units rely on a complex electrical system to work properly. If there is a problem with the wiring or connections, your AC may fail or malfunction. If you notice a tripped breaker or a blown fuse, it could indicate an electrical issue. However, you should never try to fix electrical problems on your own, as it can be dangerous. Call a professional to diagnose and fix the issue.

Frozen Evaporator Coils

When the evaporator coils get too cold, they can freeze over, which can block airflow and reduce your AC's cooling capacity. The cause of frozen coils can vary but may include dirty air filters, low refrigerant levels or poor airflow. To fix this problem, turn off your system, let the ice melt and replace the filter if it's dirty.

Odd Noises

If your AC produces unusual noises, it's often a sign of some mechanical issue. Squealing, grinding or rattling sounds may signal a loose belt, motor bearing issues or damaged fan blades. If your AC is making loud noises, the best course of action is to turn it off and call a professional to diagnose and fix the problem.
