Heat Pump Repair and Replacement in Stone Mountain

Heat pumps relocate warmth instead of generating it. In cooling mode it works like any central air conditioner, and in heating mode a valve flips the refrigerant's direction so the outdoor coil gathers heat from the air and brings it inside. Since it runs through summer and winter, a heat pump logs far more running time than a summer-only AC, and that mileage shows up in capacitors, contactors, fan motors, reversing valves, defrost controls and sensors. It also does things that alarm new owners. On a cold, wet morning the outdoor fan may stop and the unit may hiss and send up a plume of steam for a few minutes. That is defrost, and it is normal. During a hard freeze the system may lean on electric backup strips, or in a dual-fuel setup let a gas furnace take over, and that is by design too. Signs of a real problem include a coil that stays packed with ice, backup heat running all the time, cool air in heating mode, a unit stuck in one mode or a loud reversing valve. We test the system in heating and in cooling, find the failed part and price the repair before starting. When an older heat pump is worn through, we size and install a replacement with the same care.
