You rely on your home cooling system to stay comfortable in your space, especially during the warmest times of the year. When your AC cooler starts to give you trouble, you should know how to identify the problem and troubleshoot it. Here are a handful of common AC issues and what they mean.

4 Common Home Cooling Problems

1. Odd Noises

Squealing and screeching often indicate a faulty belt or blower motor bearing. To correct this issue, fill the oil port with lubricant. Clanging, rattling, and banging may point to a problem with the blower assembly or motor, which will require professional assistance.

2. Condensation

home coolingWhen condensation drips from your home cooling system, refrigerant leaks may have caused the coils to freeze, resulting in the dripping of water as they thaw. Evaporator coils may also freeze and produce excess condensation when dirt and debris oversaturate the filters, so clean or replace them monthly.

3. Lukewarm Air

In some cases, lukewarm airflow is the result of a thermostat that either needs to be replaced or recalibrated. Another reason why you may notice a lack of cool airflow is when refrigerant levels are low. Refill your unit with coolant, and check for leaks in the reservoir.

4. Breakdowns

In the event that the home cooling unit fails to run, replace the batteries in the thermostat. If that doesn’t work, reset the breakers for the AC system. It may be time to look into professional repairs or a replacement system if all else fails.
