Try Changing the Thermostat Batteries

The first step in HVAC troubleshooting is to try changing the thermostat batteries. This is the most simple, fastest fix. In general, a thermostat should get new batteries every eight to twelve months

Fresh batteries allow your thermostat and air conditioning unit to communicate like they were designed to do. 

Save energy in your home and your wallet by turning your thermostat seven to ten degrees for eight hours a day from the standard-setting. This method saves you as much as 10 percent on your cooling and hitting bill every year.

Consider Replacing the Air Filter

One of the first things an HVAC technician may deduce is the need to replace the air filter on your HVAC unit. An unchanged air filter accumulates debris, such as:

  • Dirt
  • Pebbles
  • Dust
  • Air pollutants

When blocked with excessive debris, your HVAC unit cannot work properly. As a general rule, if you can’t remember the last time you changed your air conditioning filter, it’s time to change it. 

Check on Your Air Vents

Another common culprit of HVAC system issues is the air vents. Be sure to check on your air vents and ducts and make sure they’re clear of any dust and dirt.

If you neglect your air ducts and vents for long periods of time, they can become infested with things like vermin and mold, which is a much bigger problem. Be on the lookout for strange noises coming from your HVAC unit.

If you have issues with your outdoor air conditioner or believe you have an improperly installed air conditioner, be sure to contact a professional for HVAC service immediately. 

Give Your Circuit Breaker Attention

One of the pro tips for HVAC troubleshooting is to giving your circuit breaker attention. Your circuit breaker works hard to stop the flow of an electric current in an electric circuit. It is an essential safety feature!
