A contractor called out to repair a heat pump in Macon County has to settle one question before anything else: what actually caused this. 59 severe weather events were recorded in Macon County, Tennessee between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, and a failed compressor or refrigerant problem is far more likely to trace back to the age of the unit or how well it was installed than to accumulated storm stress. A contractor will check refrigerant levels, electrical connections, and the condition of worn components, and the repair scope follows what they find there.
Older housing stock shapes what a heat pump repair actually costs and how long it takes to complete. Half the homes in Macon County, Tennessee were built in 1991 or earlier (2020-2024 ACS 5-year). Equipment installed in houses built that long ago has often been replaced or retrofitted once already, which means the unit a contractor opens may be a different generation than the house around it. When parts are needed, the relevant question is whether those parts are still being manufactured. A contractor working a repair here checks current parts availability before quoting, because a fix that exists on paper can stall if the component has been discontinued.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where a contractor looks when the system runs but moves no heat, and the coil is the first stop when the unit ices over or the airflow feels weak at the registers.
Inside, the air handler holds the evaporator coil and the blower fan, usually in a closet, basement, or attic. The reversing valve, which sits inside the outdoor unit, tells the system which direction to move heat, and a failed valve is often what sends a heat pump blowing the wrong temperature for the season. The expansion valve and the refrigerant lines connecting both units are also part of what a contractor traces when the diagnosis points away from the coils and the compressor.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply to the specific system in your house.
