A heat pump that stops working in Fayette County is almost always failing for reasons that were building long before any storm arrived. 71 severe weather events were recorded in Fayette County, Tennessee between 2015 and 2024. At that rate, severe weather is an occasional event for a system here, not a steady grind on its components. A contractor repairing a heat pump in this area looks first at refrigerant charge, compressor wear, and how consistently the equipment has been serviced, because those are what actually account for what they find inside.
Ductwork in a house carries what it carried from the day it was installed, and houses built before the current generation of heat pump technology was standard often have supply and return configurations that have simply been worked around, not redesigned. Half the homes in Fayette County, Tennessee were built in 1999 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock like this finds wear patterns that reflect that history: refrigerant lines routed through tight original chases, components that have run harder than they should because airflow was never quite right. The parts question is real too. Repair turns on whether what the opened system needs is still manufactured, and on whether what surrounds that system will let a repair hold.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor, which is the part a contractor heads to first when a heat pump stops doing its job. A failed compressor, a refrigerant leak, or a worn contactor all show up here. The coil wrapped around the inside of that cabinet is another early stop, since a bent or dirty coil changes how the whole system behaves.
Inside the house, the air handler holds the indoor coil and the blower motor that moves conditioned air through the home. A refrigerant line set connects the two units, and a reversing valve inside the system is what lets a heat pump heat and cool. When that valve sticks, the system often runs but delivers the wrong temperature.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what work is needed in your specific home.
