When you have AC problems, you may not even consider that it is actually your thermostat that is the cause of these problems. However, thermostat problems are very common. Before you give us a call for AC repair in Louisville, consider that you may need to troubleshoot issues with your thermostat, first.

Keep reading to learn more about how to know when your thermostat is the problem with your air conditioner not working correctly. Then give us a call if you need help with either of these systems and we can come up with a solution. 

AC Problems Caused By Your Thermostat

Common air conditioner problems that can stem from thermostat problems include: 

  • Short cycling – Your air conditioner is turning on and off frequently instead of completing cooling cycles. If the thermostat cannot accurately read the temperature in your home, it may signal for the AC to turn off early during a cycle. 
  • Hot spots – If You have rooms in your house that are not getting as cool as the other rooms, you may be able to blame your thermostat. If cooling cycles are not lasting long enough, the air is not distributed throughout your entire home. 
  • No cool air – If you can hear a fan running, but no cool air is coming out of the vents, your thermostat may have lost its connection completely to your air conditioner’s compressor. When this happens, it cannot turn the compressor on to begin the cooling process and blow conditioned air into your home. 

How to Troubleshoot Your Thermostat

The first step in troubleshooting your thermostat is to make sure that the settings are correct. It may seem silly, but there’s always a chance someone bumped your thermostat and set it to heating instead of cooling.

It’s also possible that you don’t have the temperature set correctly, so your thermostat is not signaling your air conditioner to turn on and cool your home. If you check both of these things, and your air conditioner is still not working, there are a few things that could be wrong. 

If the thermostat is miscalibrated, it cannot communicate with your AC correctly. Miscalibration can also mean that your thermostat reads the temperature incorrectly so that it is signaling for your air conditioner to turn on and off at incorrect times. Our team can come out and recalibrate your thermostat to communicate with your air conditioner and read the indoor air temperature accurately. 

There is also a chance that the inside of your thermostat is simply dirty and needs to be cleaned out. Dust and dirt particles can get into your thermostat and collect over time. Keep in mind that your thermostat is a very intricate system and trying to clean it yourself could do more damage than good. Instead, give our team a call so that we can help you clean your thermostat without the risk of damage.

Another common problem we see is that your thermostat batteries need to be replaced. As the batteries are dying, or if they stop working completely, your AC’s functionality could be negatively impacted. It’s possible that you will notice malfunctions before your thermostat stops communicating with your air conditioner completely.
