Yes, that's a classic sign of a failed AC capacitor, which is a common issue in our area, especially during peak summer heat. The capacitor helps start your outdoor unit's compressor and fan motor. When it fails, the system can't cool properly. Our technicians carry common capacitors on our trucks and can often diagnose and replace it in a single visit to get your cool air flowing again quickly.

This is often caused by a problem with the reversing valve, a key component that switches your heat pump between heating and cooling cycles. Debris, electrical issues, or mechanical failure can cause it to stick. As local experts familiar with this issue, we can test the valve's operation, check related controls, and perform the necessary repair or replacement to restore your system's proper function for our Missouri seasons.

First, check your home's circuit breaker panel to see if a breaker for the HVAC system has tripped—this can happen during capacitor or compressor issues. If resetting it doesn't work, or if the problem recurs, it's time to call us. Sudden failures often point to electrical components like capacitors or contactors. We offer emergency service to diagnose the root cause and provide a safe, lasting repair to prevent further interruptions to your comfort.
