Grissom Heating and Cooling | HVAC Services in Denver, NC 28037

Yes, a faulty reversing valve is a common cause for this problem in Denver, especially as seasons change. This crucial component directs refrigerant flow to provide either heating or cooling. Symptoms include the system blowing cool air when set to heat, or vice versa. Our technicians can diagnose valve issues—whether it's electrical failure, mechanical sticking, or refrigerant pressure problems—and perform the precise repair to restore proper function.

This is a classic sign of a failed AC capacitor, a very common repair we handle for Denver homeowners. The capacitor provides the necessary jolt of electricity to start the compressor and fan motors. When it fails, the system can't overcome inertia to begin cooling. We carry a wide range of capacitors on our service vehicles and can typically replace yours quickly, getting your cool air flowing again to beat the North Carolina heat.

First, check your home's circuit breaker panel to ensure the HVAC breaker hasn't tripped. If resetting it doesn't work, give us a call. For sudden failures—like no cooling on a hot day or no heat during a cold snap—it's often a component like a capacitor, contactor, or a safety switch. We prioritize these emergency calls for our Denver neighbors. Our technician will diagnose the root cause, explain your options, and get your system running reliably again.
