Troubleshooting Your AC Unit Before Replacement

If you have a broken AC unit over 10 years old, there’s a good chance it’s due for an AC replacement.

There are, however, some quick and easy solutions you can try on your own. Below is a list of common issues, causes and remedies for HVAC systems.

Potential cause

  • You may have a tripped circuit breaker in your home
  • Your thermostat may be off or set incorrectly
  • Your indoor unit is running, but the outdoor unit is not

First course of action

  • Check your home circuit breaker box
  • Check to make sure your thermostat is on and set to cool
  • Air coming through your vent will be warm. Check temperature setting

Suggested solution

  • Reset circuit breaker
  • Reset thermostat to your desired temperature
  • Contact Smith and Willis. In the meantime, try turning off your thermostat for 1–3 hours to see if it will reset
