As the weather warms up, it won’t be long before you’re blasting your AC. With the unit running constantly, there is a higher chance that a problem will pop up. However, if you know what to expect, you can quickly diagnose the problem and get HVAC system repairs. The guide below explains some common AC malfunctions.

What Issues Do AC Units Experience the Most?

1. Cycling On & Off

If your AC system runs all the time, it may be struggling to cool your home adequately. This problem may be caused by faulty wiring or a malfunctioning thermostat.

It may also be the result of inadequate maintenance due to dirty condenser coils or a clogged air filter. This problem can cause your HVAC system to wear out faster and waste energy.

2. Blowing Warm Air

If the air coming from your vents feels warm, the HVAC system may need a refrigerant recharge or it may have a refrigerant leak.

It may also be caused by an outdoor condenser unit that’s clogged or crowded by vegetation, limiting ventilation and heat exchange. If you’ve cleaned the condenser and the problem hasn’t resolved itself, call an HVAC system expert.

3. Unusual Noises

Your HVAC system may make some noises during operation, but if you hear hissing sounds, the unit may have a refrigerant leak. Loud thumping or rattling noises often indicate an issue with the blower motor. Screeching or squeaking may be caused by a faulty fan motor or a fraying belt.

4. Clogged Drain Line

As your AC operates, it generates some condensation that needs to be carried away from the unit by a drainage line. If you notice water pooling near the unit, the drainage line may be clogged. This problem can lend itself to mold and mildew growth, so it should be resolved as soon as you notice it.
