AC Maintenance in Raceland, LA

Dealing with an air conditioner that suddenly stops cooling can be quite frustrating. This problem can occur for a variety of different reasons, many of which will need to be fixed by an HVAC technician. Nonetheless, the problem may also be something you can fix fairly easily. Here are the things you’ll want to check whenever your AC isn’t cooling.

Replace the Air Filter

Your AC air filter should always be replaced regularly to prevent it from getting dirty and clogging. If the air filter is clogged, it will limit airflow. That means the AC is limited in how much air it can cool. For this reason, the very first thing we would recommend doing if your AC isn’t cooling is to replace the air filter.

Wait for Evaporator Coil to Thaw

Sometimes your AC may not be cooling due to a frozen evaporator coil. This is often caused by a clogged air filter. If the evaporator coil is frozen, the warm air won’t be able to come into direct contact with the coil.

If you suspect the coil is frozen, you should immediately switch the thermostat off. Continuing to run the AC with a frozen evaporator coil can damage the unit. Evaporator coils can take up to 24 hours to thaw. If the coil quickly freezes up again, you will need to have a technician inspect the system. The same is true if the coil isn’t frozen, and replacing the air filter didn’t fix the problem.
