One of the most vital components of your air conditioning system’s functionality is its thermostat. While you may not immediately trace your AC malfunctions back to a thermostat issue, the device plays an important role in keeping your unit running. In truth, even a minor thermostat failure can lead to several serious AC problems. Here is a list of five AC issues that are caused by a malfunctioning thermostat.

1. Frequent Cycles

A frequent cycle is what results from the compressor shutting off before finishing its cooling cycle. It will then turn on again and repeat the same short cycle. This may stem from a malfunctioning thermostat sensor. The failing sensor will lead your compressor to complete its cooling cycle prematurely. These false readings will cause your AC unit to be stuck in a loop where it cycles on and off repeatedly. You will begin to notice that your utility bills are shooting through the roof. Repairing or replacing the sensor should improve the situation.

2. Non-Stop Running

If you notice that your blower fan operates non-stop, there may be an issue with the wiring that connects the thermostat to your AC system. Our technicians are qualified to detect any shorted circuits in your system. Another problem could be that you’re simply using the wrong thermostat fan setting. If your thermostat is set to “ON,” it will cause the fan to constantly blow even when your system isn’t cooling your environment. This is likely to cause a few issues including:

  • High humidity
  • More repairs
  • High energy bills
  • Air duct leaks

3. Not Cooling Enough

You may also find that your AC system does not cool your room despite it running for a long period. If this sounds familiar, it is vital to check the calibration of your thermostat. An incorrectly calibrated thermostat means that your AC unit won’t get the right instructions from the control system. This will result in your cooling system not regulating the temperature in your household to the desired levels. Let our skilled technicians recalibrate your device. If you set the thermostat to its coldest setting with no improvement, it may be time to consider an upgrade. Our technicians will replace your aging thermostat to resolve the issue.

4. Cooling Too Much

In certain scenarios, your air conditioner may get too cold for comfort. You may notice that the indoor temperatures feel much colder than the setting that your thermostat indicates. Our technicians will make sure that your device does not give false readings. Other than incorrect calibrations, this issue could be caused by a heat source being placed too close to the thermostat. The thermostat’s functioning is then affected because it reads the room’s temperature to be warmer than it actually is. As a result, the unit will work extra hard to reach cooler than desirable levels. Our team will make sure that your thermostat is placed away from direct sunlight, light bulbs, and any other objects that may interfere with its operation.

5. Not Working Completely

If your AC unit is not working at all, it is important to inspect the thermostat. Specifically, there may be an issue with the thermostat’s batteries. This is more prevalent with the additions of smart thermostats that are touch screen as every interaction will use up some of the batteries. If the batteries are dead, there is no mechanism for the AC unit to know when to start cooling. At this point, your AC will permanently stall in an inactive state. In other cases, you may find that your batteries are in good working condition but your AC system still doesn’t run. When this happens, our technicians will make sure that your thermostat is in its “cooling” mode. Moreover, our team will ascertain that your device has the correct temperature settings. If none of these options resolve your AC issue, it may be useful to replace the thermostat altogether.
