Cooling System Troubleshooting: How to Diagnose Common Problems


It’s no secret that this summer has been a hot one. The summer heat has been strong no matter where you are across the United States. And, as we head into August and September, that heat won’t cease.

Hot weather in itself is frustrating. But, if you don’t have air conditioning or your air conditioning stopped working, that opens up a whole new level of pain and frustration for homeowners. Just when you needed it most, it failed you.

Air conditioning repair can be pretty pricey depending on the company you choose or what needs to be repaired. However, many air conditioning problems can be fixed by a handy homeowner!

There are many different types of heating and cooling systems that are used in homes and offices in the United States. If you are suffering from a malfunctioning heating or cooling system this summer, then read on to find out how you can fix it. It is not always necessary to call a professional maintenance specialist to fix a heating or cooling system.


Is it turned off or obstructed?

If your cooling system is not working at all, then you should first check to make sure that it is turned on. For example, sometimes people forget to turn on their cooling system before they go to bed, and the unit does not work in the morning because the thermostat is turned off. You should also check to make sure that the unit is not blocked by furniture or other objects which could be obstructing airflow.

Is it not cooling the room?

If the cooling system is on but not cooling the room, the problem may be caused by a dirty air filter, a blocked unit, or a malfunctioning thermostat. You can try to clean the air filter yourself, but typically, the problem lies deeper than the surface. You may have to call an air conditioning cleaning expert to give your unit a nice, deep clean. If the thermostat is not working, you will need to replace it.

Is it not blowing cold air?

If the cooling system is on but not blowing cold air, the problem may be caused by a dirty evaporator coil, a low refrigerant level, or a clogged compressor. You can try to clean the evaporator coil or check the refrigerant level. If the compressor is plugged, then you will need to replace it.


Is the room not staying cool?

If the cooling system is cooling the room but not keeping the room at the desired temperature, the problem may be caused by a malfunctioning thermostat or a refrigerant leak. You can try to adjust the thermostat, or you may need to call in a professional to fix the refrigerant leak.

Is it making strange noises?

If the cooling system is on but making strange noises, the problem may be caused by a dirty or clogged compressor. You can try to clean the compressor, or you may need to replace it. If the cooling system is not on, then the problem may be caused by a tripped breaker or a blown fuse. You can try to reset the breaker or replace the fuse, but if the problem persists, you may need to call a professional.

Sometimes, these problems can be fixed ourselves. But, if you aren’t handy or don’t have the time to solve the issues at hand, you can call an air conditioning repair company trusted by your community.
