A contractor quoting a heat pump repair in Chatham County has to establish what the system has already been through before settling on a cause. 343 severe weather events were recorded in Chatham County, Georgia between 2015 and 2024. At that rate, severe weather is a standing condition for equipment here, not an occasional disruption, and components like the compressor and capacitor have been carrying that load across every cooling and heating season. That history shifts where a good diagnosis starts: weather-related wear gets ruled in or out first, and the bill follows from what the contractor actually finds inside the unit.

Heat pump repair in housing stock like this turns on what the opened equipment actually shows, not what the permit or the age of the house would predict. Half the homes in Chatham County, Georgia were built in 1986 or earlier (2020-2024 ACS 5-year). That history matters for repair work because a system installed into an existing house carries the load of whatever decisions were made when it was fitted: refrigerant charge set by eye, connections made to whatever was already there, previous fixes that held until now. A contractor pulling a unit apart here finds the repair scope shaped as much by that accumulated context as by the component that failed.
The Parts of a Heat Pump a Contractor Checks During Repair

The outdoor unit is usually what a contractor reaches first. It houses the compressor, which drives the whole system, and the outdoor coil, which absorbs or releases heat depending on the season. A fault in either one shows up quickly: the compressor may run loud, short-cycle, or not start at all, while a damaged coil often shows as ice or poor output.
Inside the house, the air handler holds the indoor coil and the blower fan, which pulls air across the coil and pushes it through the home. The reversing valve, usually inside the outdoor cabinet, is what lets a heat pump both heat and cool. The expansion valve and refrigerant lines tie the two units together, and a refrigerant leak or a stuck expansion valve will affect both sides of the system.
The drawing shows a typical heat pump layout, and a licensed contractor determines which parts apply to the specific system and conditions in your home.

Weather places real demands on heat pump systems, and those demands vary by location. How hard the equipment works, and how often it is pushed to its limits, is shaped by what the local climate actually does.
