A heat pump in Polk County that needs repair is statistically unlikely to be wearing out from weather stress. 73 severe weather events were recorded in Polk County, Georgia between 2015 and 2024. At that rate, severe weather is an occasional event in this area, not a standing condition equipment has to outlast. A contractor quoting a repair here will find that the refrigerant lines, compressor wear, and electrical contacts tell a story driven by age and service history, not by storm cycles. Skipping to weather as an explanation wastes the diagnostic.

A heat pump sitting in a house built well before that equipment existed was almost certainly swapped in to replace something older, and the internals reflect that history. Half the homes in Polk County, Georgia were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor who opens a failed unit here has to determine whether the parts that system takes are still in production, because a generation of equipment changeover separates the house from whatever is running in it now. Sourcing a replacement component for a system installed into older stock is a different job than ordering off a current parts list.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits outside the house and holds the compressor and the outdoor coil. These are the parts a contractor reaches first when something goes wrong, because the compressor drives the whole system and the coil is where heat actually transfers. A fault in either one shows up fast.
Inside, the air handler holds the indoor coil and the blower fan, usually in a closet, attic, or utility room. The expansion valve sits between the two coils and controls refrigerant flow. The refrigerant lines connect the indoor and outdoor sides, and a refrigerant leak or a failing valve can produce symptoms that look like a compressor problem until a contractor traces the source.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific setup.

Storm activity puts real strain on heat pump systems, which run harder to hold a set temperature when outdoor conditions swing hard. Repair demand in Polk County tracks the local weather, and the chart below shows the recorded event history that shapes that load.
