Air Conditioning FAQ: Problems That Can Be Caused by Your Thermostat

We are in the hot days of summer here, so you need to make sure that your air conditioning system is up to the task of keeping you cool for the rest of this summer and beyond. This is the worst time to encounter serious problems with your AC. With professional installation and routine maintenance, you can eliminate many of the repair needs you would otherwise encounter from year to year, but no system is perfect. There are numerous components and mechanisms that make up your air conditioner, but in today’s post, we’ll focus on the thermostat, particularly problems that it can cause when it’s not working well. Call AAction Air today for comprehensive Savannah, GA air conditioning services.

  • AC won’t turn on: Before you call us, check that your thermostat is calling for cooling, and that the fan is turned on. Also, make sure that the AC hasn’t blown a fuse or tripped the circuit breaker. If it’s still not working, your thermostat may be broken. It could be a problem with the temperature sensor, so that it doesn’t communicate the correct temperature to the controls on the AC unit.
  • AC won’t turn off: You may not want your AC to turn off, considering the heat and humidity, but a properly sized and professionally installed air conditioner should not run continuously. Its operation should be divided into cycles; when it reaches your desired temperature, it should shut off. Continuous operation can lead to increased wear and tear on system components as well as energy inefficiency. This could be a symptom of a problem with the thermostat.
  • Not enough cool air: While there are numerous reasons for not having enough cool air in the home—from airflow blockages to low refrigerant—it may also come down to a problem with the thermostat. When you create a desired setpoint, your air handler should react accordingly, but if your AC is unresponsive, then it may not be getting the right information.
