Condenser Not Kicking On But Air Handler Is? Troubleshoot Here!

Is your air conditioning (AC) system failing to cool your home effectively? One common culprit could be your condenser not turning on. Understanding the reasons behind this issue can help you troubleshoot and explain the problem better when seeking professional help.

Initial Troubleshooting Steps

Before calling a professional, try these preliminary checks if your AC condenser isn't activating:

• Check the Circuit Breaker: Look at the breaker panel for any tripped breakers and reset them if required.
