Guide To Common Home & Residential Ac System Repairs

Are you seeing issues with your home AC system? Are you wondering what issues you can take care of yourself?

Air conditioner systems are dangerous to work on if you’re not a trained professional. Here’s a guide to the most common home AC system problems and what to do about them.

Refrigerant Leaks

There should be no reason why your AC system is low on refrigerant. If it is, check for leaks.

If you find a leak, you’ll notice refrigerant pooling or dripping in the unit. Get a contractor to fix this.

Filter Problems

If you’re noticing reduced performance, and can’t remember the last time you replaced the filter, check and replace or clean your filter.

Some filters can be cleaned, others must be replaced. Check which filter you have and see the manufacturer’s instructions.

A filter can be cleaned or replaced by yourself. Follow the instructions in the manufacturer’s manual for your unit.


Drainage problems can cause high humidity levels in the home.

Check the condensate drain to make sure it’s continuing to drain. Also check for clogs in the drain line. You will want to get a contractor to do this.

Thermostat Issues

Thermostats come in many different forms. If you notice that your thermostat isn’t functioning, first try to troubleshoot the thermostat unit before inspecting the rest of the HVAC system.

Call the manufacturer of the thermostat to help troubleshoot issues with it.

Compressor Fan

A broken compressor fan will prevent your air conditioner from working properly. What’s worse is that it could cause the compressor to overheat.

Depending on the compressor, it could turn on the safety controls which ends up shutting off the AC unit. Or, it could cause overheating damage to the unit itself.

Contact a home AC repair contractor to check this particular issue. It could require that the compressor fan be replaced.

Frozen Condenser Coils

Frozen condenser coils are pretty common if there is poor airflow through the cooling system. This is usually caused by a buildup of dust and debris.

A contractor should take a look at your AC unit and see if this is the problem. They will be able to remove any obstruction and thaw out the condenser coils, and this should return the unit to full working capacity.
