Heat Pump Services in Suwanee, GA

A heat pump earns its keep twice a year. Through the long, humid summer it cools like any air conditioner. When the weather turns, a reversing valve flips the flow of refrigerant and the same outdoor unit pulls heat from outside air and moves it indoors. That is why so many Suwanee homes rely on one, and why a weak heat pump shows up as discomfort in both seasons. Some behaviors are normal and worth knowing. In cold, damp weather the outdoor coil collects frost, and every so often the unit melts it off: the outside fan pauses, a hiss or whoosh is common, vapor may drift up, and then heating picks back up. During a hard freeze, auxiliary heat, often electric strips in the air handler, supplements the heat pump. In a dual-fuel system a gas furnace takes that role. Other behaviors call for a technician: frost that turns into solid ice, a unit stuck in heating or cooling, auxiliary heat running constantly, or rooms that never reach the setpoint. Our checks cover the reversing valve, the defrost board and its sensors, capacitors, the fan motor, the refrigerant charge and the backup heat. When replacement is the better path, the new heat pump is sized to the house and its ductwork.
