Signs You Need To Replace Your Air Conditioning Thermostat


Your air conditioner's thermostat is an extremely important part of your HVAC system, as it allows you to control and change the temperature levels within your home. An improperly functioning thermostat can reduce your overall comfort levels and increase your energy bills. Thankfully, there are a couple of early warning signs that you can look out for to help determine when it's time to replace your air conditioner's thermostat.

Temperature Changes

One of the clearest signs that you need to have an HVAC professional come in to take a look at your thermostat is if there are frequent and severe temperature changes within your home. It doesn't matter if it suddenly gets hot or cold, just the fact that it is changing. This usually points to the inability of the thermostat to control your central air conditioning unit adequately, causing it to turn on or off when it shouldn't.

Incorrect Readings

Another fairly common sign of a failing air conditioning thermostat is if the reading on the thermostat is wrong. You won't be able to tell this simply by sight unless the reading is off by several degrees, so it's a good idea to get a thermometer to check the ambient temperature around the thermostat every once in a while to ensure that it is an accurate reading. If it isn't, you should begin to look into replacing the thermostat.

Inability to Change Temperature

In a similar vein to the above point, if your air conditioning unit works normally, but only seems to run on a single setting and can only change the temperature to a single value, your thermostat is most likely to blame. You should contact an HVAC professional as soon as possible to have the thermostat replaced, as the inability to change the temperature of your home beyond a single value can greatly reduce your overall comfort levels.

Air Conditioner Won't Turn On or Off

If your air conditioner won't turn on or off at all, no matter what setting you set your thermostat to, the thermostat may need to be replaced. This is usually because of a damaged wire that prevents the thermostat from communicating with the air conditioning unit. However, it's a good idea to get in touch with a contractor to take a look at your air conditioning unit, as a non-functioning or constantly functioning unit can be caused by internal damage within the central unit itself.
