A heat pump failing in Sequatchie County is almost never a weather story. 56 severe weather events were recorded in Sequatchie County, Tennessee between 2015 and 2024. At that rate, severe weather is an occasional event in a system's life, not a steady load that grinds components down. What contractors find when they open a unit here points to refrigerant leaks from aging coils, worn contactors, or compressors that ran for years on an undersized install. The weather record does not excuse those failures, and chasing it as an explanation delays the repair that actually fixes the problem.
Much of Sequatchie County's housing was already standing before the heat pump generations now running in it were manufactured. Half the homes in Sequatchie County, Tennessee were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in a house built around that period is not looking at a recent system, and the refrigerant lines, electrical connections, and internal components reflect years of seasonal load. What matters on that service call is whether the failed part still ships. Some components in systems of this age are sourced through specialty channels, which changes how long a repair takes and what it costs.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit sits on a pad beside the house and holds the compressor and the condenser coil. The compressor is usually where a contractor looks first, since a failed compressor explains most cases of a heat pump that runs but moves no heat. The condenser coil and the fan motor that pulls air across it are checked next.
Inside the house, the air handler holds the evaporator coil and the blower motor, which push conditioned air into the living space. The reversing valve, which sits in the refrigerant line and tells the system which direction to run, is a common repair target. The expansion device and the refrigerant lines connecting both units round out what a contractor examines.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to the specific setup in your house.
