How a Faulty Thermostat Can Damage Your AC

The thermostat is one of the most vital parts of an air conditioning system, one that people interact with on an almost daily basis, and one of the few parts of an AC that sits in plain sight—yet few homeowners ever give it much thought. If the thermostat malfunctions, your home’s cooling and the system that takes care of it could be in for trouble.

When a malfunctioning thermostat causes problems, you need to call for expert air conditioning repair in Tampa Bay, FL from a company with NATE-certified technicians and the training to handle any necessary work. You need to call Ierna’s Heating & Cooling. We have same day emergency service, so don’t hesitate to call when you need that air conditioner repair done now.

Some AC problems due to a malfunctioning thermostat

When a thermostat develops repair problems, it will often lose its connection to the air conditioner. In such cases, although you will need repair technicians to fix the thermostat, you shouldn’t have damage to the AC itself that will need work.

However, there are ways that a thermostat can go wrong that will cause serious problems for the air conditioner. One of them is when a miscalibration in the thermostat leads to a short-cycling AC. “Short-cycling” is when an air conditioner’s cooling cycle turns off before it can finish: the compressor begins its work, and then abruptly shuts off because the thermostat has incorrectly determined that it has reached its target temperature. But soon after the compressor turns off, it will turn back on again, starting the process anew.

The reason this will turn into a significant AC repair problem is because it places severe stress on the compressor, the most valuable part of an air conditioner and the most expensive component to replace should it fail. The start-stop action of short-cycling is one of the worst things that a compressor can undergo. The stress isn’t limited to the compressor either: it will also affect the motors and cause them to burn out.

The wires in the thermostat that connect to the AC can fail in a way that will cause the air conditioner’s fan to run without stop, and this is also potentially very damaging for the AC as it places heavy strain on the fan motor.

Issues with the thermostat often initially appear as problems in other parts of the AC (for example, short cycling can occur because of a loss of refrigerant), so you may not know that the thermostat is the cause at the beginning. However, your repair technician can track the source of the malfunction, so whenever you detect anything amiss with your cooling system, get on the phone and call a reputable repair contractor.

You can also call us for upgrades to your current thermostat to a more efficient model.
