A heat pump repair in Shelby County starts with a question a contractor has to settle before pricing anything: how much of the wear in front of them came from the load this climate puts on equipment, and how much came from something the weather had nothing to do with. 269 severe weather events were recorded in Shelby County, Tennessee between 2015 and 2024. At that rate, severe weather is part of the normal operating life of every system here, not an occasional exception. A compressor that is running hard through repeated stress events accumulates wear in its valves and refrigerant circuit differently than one that rarely faces that load, and a contractor looks at those components first. The repair scope follows from what they find.

Ductwork in a house of this age has seen multiple systems come and go, which means the heat pump sitting in it now is rarely the original equipment and often not even the second. Half the homes in Shelby County, Tennessee were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor who opens a failing heat pump here has to establish what generation of components is inside it and whether those parts are still in production. Refrigerant fittings, reversing valves, and control boards each have their own supply situation, and a unit that looked repairable on the outside can stall a job when the part it needs stopped shipping years ago. That is the variable that sets the scope and the price, and it only shows up once the unit is open.
The Parts of a Heat Pump a Contractor Checks During Repair

The outdoor unit sits beside the house and holds the compressor and condenser coil. The compressor is usually the first thing a contractor tests when a heat pump stops moving heat properly, because a fault there affects the whole system. The condenser coil and the fan motor that draws air across it are examined alongside it.
Inside the house, the air handler contains the blower motor and the evaporator coil, which are both common sources of airflow and performance problems. The reversing valve, which sits in the refrigerant line and tells the system which direction to run, is another part a contractor looks at early when the heat pump runs but heats or cools poorly. The refrigerant lines connecting the two units and the expansion valve that meters refrigerant flow are also checked.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what condition each one is in.
