What To Do About Common Thermostat Problems

Your air conditioner is one of those things that you hope you can just set and forget, but it doesn't always turn out that way. Problems with your thermostat can both ruin your comfort and run up your energy bills. If you suspect there's something wrong with your thermostat, here's what you can do about it.

The Temperature Just Doesn't Feel Right

Let's say you have your thermostat set to 76 degrees and your air conditioner always turns on when it gets up to 77 degrees and turns off when it gets back down to 75 degrees. Your home also feels evenly cool in every room. If this is the case, the problem may be your perception instead of your thermostat. Indoor and outdoor temperatures feel different due to sunlight, wind, humidity, and other factors. Different homes or other buildings can feel different at the same temperature. 

However, if you still don't believe your thermostat, place a thermometer on top of it and check it. If it turns out your thermostat isn't calibrated properly, your AC repair technician can replace it.

Your AC Won't Turn on at the Set Temperature

If your AC won't turn on when it rises above your set temperature, first check the basics. Double-check that your thermostat is on, set to AC mode, and at the temperature you think it's at. Then make sure you haven't tripped your circuit breaker or accidentally flipped off a power switch that controls your AC.

If everything is set properly on your end, it's usually a sign that one of the thermostat wires has corroded or lost its connection to your AC. That requires a professional repair.

Your AC Won't Turn Off at the Set Temperature

You may also have an AC that won't turn off when it reaches your set temperature. First, feel if the air coming out is still chilled. If it's coming out at room temperature, you may have turned on the fan setting, causing the system to run continuously in the "on" position instead of the "auto" position.

If that's not it, an AC that won't turn off is usually a sign of a wiring problem. Your wires have become loose or corroded so that the connection is lost when your thermostat tries to tell your AC to turn off after hitting the right temperature. This is also something that requires a professional fix.
