Flatt Plumbing & Heating: Best HVAC Services Serving Knoxville 37921

Yes, absolutely. A comprehensive plumbing inspection includes checking the condensate drain line from your air handler. If this line clogs, it can cause water to back up and damage the air handler's fan motor or controls. Our inspection ensures this critical drainage system is clear, helping to prevent a common cause of air handler failure in Knoxville homes.

Knoxville's humidity and temperature swings can stress thermostat wiring and components over time. During a service call, our experts diagnose whether the issue is with the thermostat itself, its wiring, or a signal problem from your HVAC system. We provide clear explanations and reliable repair or replacement options to restore accurate temperature control.

First, check your home's circuit breaker to ensure power is reaching the unit. Next, verify the thermostat is set to 'Cool' or 'Heat' and the fan setting is on 'Auto' or 'On'. If these simple steps don't resolve it, the issue could be a faulty capacitor, motor, or control board—common failures we see locally. It's best to call us for a safe, professional diagnosis to prevent further damage.
