HVAC Services Greeneville TN | Call Parton's Electric-Heating & Air Conditioning

This is often due to a failing reversing valve, a common issue in our area as systems age and cycle frequently. The valve can become stuck or leak refrigerant, preventing the proper mode change. Parton's technicians are experts in diagnosing and repairing or replacing these valves to restore your heat pump's full functionality for year-round comfort.

High humidity is a persistent challenge here. If your AC is running but not dehumidifying properly, it could be short-cycling, have a dirty evaporator coil, or be incorrectly sized. Our team performs detailed evaluations to ensure your system is not only cooling but also effectively removing excess moisture for true comfort.

Given our high humidity and temperature swings, biannual maintenance is key. In spring, we focus on cooling system checks, ensuring proper refrigerant levels and clean coils for efficient dehumidification. In fall, we service heat pumps, specifically testing the reversing valve and defrost cycle to prevent winter failures. This proactive care from Parton's helps prevent the most common local breakdowns.
