Heat Pump Services in Lilburn

Heat pumps make a lot of sense in Lilburn. Summers are long and humid, winters are mostly gentle and one outdoor unit can handle both by reversing the flow of refrigerant. But a heat pump is even pickier about sizing than a plain air conditioner. Size it for cooling alone and it may lean hard on its electric backup heat every cold night. Size it too big and it short cycles all summer and leaves the house damp. So every heat pump we install starts with a load calculation for both seasons and a look at the ducts. Some homes do best with a heat pump alone; others do better teamed with a gas furnace, letting the burners handle the bitter nights. We also repair and maintain existing heat pumps, and we will tell you which odd behaviors are normal. Steam rising off the outdoor unit on a frosty morning? That is the defrost cycle. An aux heat light during a hard freeze? Expected. A coil that stays iced, long stretches of cool air in heating mode, backup heat running constantly or a unit stuck in one mode are not normal, and usually point to defrost controls, a reversing valve, refrigerant charge or a fan.
