3 Common Preventable Causes of AC Failure

Hand Holding Remote For Air Conditioning SystemYour air conditioning system could be failing because of simple things you left unattended for weeks, like a loose wire. It's easy to mend these small problems without having to spend too much. All you need is to know what to do and who to call.

Refrigerant running low

The refrigerant is the fluid in the air conditioning system that removes heat from the air. When your system starts developing cracks and the refrigerant leaks, the AC will stop working correctly. The refrigerant will leak through the cracks and the system will end up with less than enough refrigerant. You cannot fix this problem by adding more refrigerant since it will continue leaking. You need to call a technician to fix the holes and the cracks.

The evaporator coils are frozen

The evaporator coils are filled with refrigerant. They work by absorbing heat from the air around them like a sponge. For them to work effectively and efficiently, there needs to be warm air around it so they can absorb the heat from the air. If the air is not circulating, the evaporator coil will get cold and a layer of cold ice will build up over it. 

Problems with the thermostat

During the AC installation for your St. Louis home, you need to know which kind of a system is being fixed in place. The older systems have a dial type kind of thermostat that's sometimes calibrated incorrectly. This means that the control system is not receiving the instructions. This is a small problem you can fix. You can either choose to replace the thermostat with a programmable one or you can recalibrate the thermostat.

You can learn more about your system by asking questions to the experts. By understanding your system, you can easily troubleshoot problems that might arise so that in the summer you don’t have a problem.
