Heat Pump Services in Johns Creek

Stand next to a heat pump and it looks just like a regular condenser. In summer it acts like one too. Come winter it flips direction, scavenging warmth from the outdoor air and moving it indoors. That trick suits north Georgia well, with long, muggy summers and winters that are mostly mild. It also means the machine never gets an off-season, so small faults snowball faster. A few things that alarm homeowners are perfectly fine. On a raw, damp morning the fan may stop, the unit hisses and a puff of steam rolls off: that is defrost melting frost from the coil. During a deep freeze electric heat strips may switch on as a helper, and the thermostat may show an aux light. What is not fine: a coil caked in ice that never clears, cool air for long stretches in heat mode, backup heat running nonstop or a unit stuck in one mode. Those usually trace to a bad defrost board or sensor, a sticky reversing valve, a low charge or a fan problem. We test until we know which. Certain houses run a heat pump alongside a gas furnace so the furnace can handle the bitter nights. We look after those dual-fuel setups as well.
