Age, installation quality, and how well the system has been maintained are what a contractor works through first when diagnosing a heat pump repair here. 33 severe weather events were recorded in Pickett County, Tennessee between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, and a refrigerant leak or a failing capacitor is far more likely to trace back to years of wear than to storm exposure. A contractor will check the compressor, the electrical components, and the refrigerant charge before weather enters the conversation at all.
Ductwork in a house this old was installed for a system that ran long before the current one was put in, which means what a contractor finds inside the heat pump matters more than what is behind the walls. Half the homes in Pickett County, Tennessee were built in 1993 or earlier (2020-2024 ACS 5-year). A unit that has been carrying the load through that many seasons shows it in the refrigerant circuit, the electrical connections, and the contactor. Those are the components a contractor opens and checks first, because in stock like this, that is where the failure lives.
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 most likely to be behind a heating or cooling failure, along with the condenser coil and an expansion valve that meters refrigerant flow. The air handler lives inside, usually in a closet, attic, or basement, and pushes conditioned air through the home. Both units carry components a contractor will test before anything else.
A reversing valve inside the outdoor unit is what lets the system heat in winter and cool in summer, and a fault there often looks like the system is stuck in one mode. The refrigerant lines connecting the two units, and the capacitors and contactors that start and run the motors, round out what a contractor works through during a repair call.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what condition they are in for your specific home.

Severe Weather Events in Pickett County
Weather puts hours on heating and cooling equipment. A heat pump that runs hard through temperature swings and storm cycles accumulates wear that shows up as repair calls, and knowing the local pattern helps a contractor read the equipment honestly.
