Jim Underwood Appliance Services - Gainesville's Top-Rated HVAC Services

Yes, that's a common issue in our area. The reversing valve is crucial for changing the refrigerant flow for heating or cooling. When it fails, your system gets stuck in one mode. Our technicians can diagnose valve issues, often caused by wear or electrical problems, and perform the precise repair to restore your comfort year-round.

Absolutely. While we repair the HVAC unit itself, mold in the ducts is a separate concern that affects your whole home's air. We recommend and can coordinate a professional duct cleaning service to remove mold and debris. We also check and repair issues like excess moisture from faulty AC drain pans, which is a common source of the problem.

Watch for insufficient heating/cooling, strange noises (like hissing from the valve), or the system being stuck in one mode. Also, a sudden spike in your energy bill can indicate inefficiency. Addressing these signs quickly with our local team can prevent further damage, especially during our variable Georgia seasons, and save you money on energy costs.
