Air Conditioning Repairs For An AC That Isn't Cooling Consistently

If your air conditioner doesn't keep a consistent temperature, it may short-cycle or be erratic. Your house might get too hot or too cold, and your power bill could go up. You should call an air conditioning repair service to find out what's going on and fix the problem. Here are some possible causes of your AC not cooling your home consistently.

The Thermostat Wire To The Condenser Could Be Bad

The thermostat signals the AC to turn on, but if the wire that goes to the condenser is bad, the signal is lost. The outdoor thermostat wiring could be bad if your dog or a rat decided to chew on it. Like any other bad thermostat wiring, the repair technician can replace it if needed.

Wiring also goes from the thermostat to the control board. Since this wire is behind the wall, it can be damaged by rodents too. If the thermostat is erratic, checking that the wires and connections are good can help narrow down the source of the problem.

The Thermistor Could Be Faulty

The thermistor is a part that's often near the evaporator coil that monitors the temperature in your home. It then signals your AC when to turn on and off. It's meant to be more efficient than relying on a thermostat alone, but if the part is faulty or bad, it needs to be replaced with a new one. The air conditioning repair technician can test the thermistor with a multimeter to tell if it needs to be replaced.

The Thermostat Is Old Or Damaged

If your thermostat is fairly new, it might be worth trying to repair if possible. If the thermostat is old, you might prefer to get a new one instead. A new one might even be necessary if the thermostat was damaged in some way.

Your air conditioning repair technician may provide a new thermostat, or they may help you choose a new one and install the thermostat of your choice. You might want to upgrade to a smart thermostat if you have a smart system installed in your home.

The AC Is Short-Cycling

Short-cycling is a condition where your air conditioner turns on and then turns off too soon. The AC can't run long enough to get your home cool. That leads to it turning back on sooner and shutting off quickly again. This puts wear and tear on the parts, and it can drive up your power bill. Even worse, your home may get too hot if the AC can't cool you down.

Several things cause short-cycling, from a clogged filter to ice on the evaporator coils. The air conditioning repair technician has to test parts to discover the cause and make repairs so the temperature in your home is consistent.
