5 Air Conditioner Troubleshooting Tips

Posted On: May 31, 2020

Air conditioning systems are essential to staying cool (and sane) during the Richmond summer months! While Short Pump Heating & Air is always available and equipped to handle any HVAC problem, we want to provide some basic troubleshooting tips if your air conditioner stops working.

  1. Make sure your thermostat is set properly – Sometimes fixing your air conditioner is as simple as properly programming the thermostat. If set incorrectly, your AC may not work the way it is supposed to, or the way you want it to perform. Double check this first before assuming it’s broken or a bigger problem than it is.
  2. Replace the air filters – When your HVAC filters get too dirty, air cannot flow through properly and efficiently. When this happens, your AC will not work as well or might even go out completely. If you notice your air conditioner struggling or it cuts off unexpectedly, and it’s been a while since you changed your filters, check and replace the filters with new ones to see if that does the trick. Another sign of a clogged filter is the development of ice around parts of the system. Ice can also be a sign of a more serious air conditioning issue.
  3. Change the thermostat batteries – If it has been a while since you checked the batteries in your thermostat, it might be time to change them. Without fully functioning batteries, the thermostat cannot communicate properly with the air conditioning unit, and it might be the reason for your issue. Many thermostats are wired in to provide power, but many rely on battery power.
  4. Check your circuit breaker – If your circuit breaker is connected to the air conditioning system and has been tripped, you may just need to simply reset it to get your system back up and running. With that said, most of the time a tripped breaker is a sign of a more complicated HVAC system issue. You may get lucky though, and everything works fine after resetting the breaker.
  5. Check for water in your drain pan – A clogged condensate drain can cause the system to stop cooling. When the air handler or coil is in the attic, it should be equipped with at least one condensate safety switch. This stops the system from cooling and producing water so that if you have a clog, it does not back up onto your ceiling. It may be a simple fix, but you may need to call an air conditioning professional to take care of the problem.

How do you know if it is time to call Short Pump Heating & Air to fix your issue?
