A heat pump repair in DeKalb County asks a contractor to figure out what actually wore the component down. 251 severe weather events were recorded in DeKalb County, Alabama between 2015 and 2024. At that rate, severe weather is a routine part of how every system here has been running, not an occasional variable, and a contractor checking a failed compressor or a struggling reversing valve has to weigh accumulated load against age and original installation quality. Both can produce the same symptom. Getting the cause wrong means replacing a part that will fail again for the same reason.
Ductwork and wiring in houses this old were put in for whatever ran first, and the heat pump that followed came later. Half the homes in DeKalb County, Alabama were built in 1984 or earlier (2020-2024 ACS 5-year). A repair that gets into the system tends to find components that have been cycling through that history for a long time, and the question a contractor faces is whether a manufacturer still makes what the opened unit needs. If the part is current, the repair proceeds. If it has been discontinued, the scope of the job changes before a quote can be written.
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 does the heaviest work in the system, and the outdoor coil, which transfers heat between the refrigerant and the outside air. When either of those fails, the whole system stops doing its job.
Inside the house, the air handler holds the indoor coil and the blower fan that moves conditioned air through the home. The refrigerant lines running between the two units and the reversing valve, which lets the system shift between heating and cooling, are also points a contractor examines when tracking down a fault.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific house and equipment.

Severe Weather Events in DeKalb County
Weather patterns in DeKalb County put real stress on heat pump systems, which run harder and cycle more often when outdoor conditions swing wide. Repair needs here are shaped by local conditions, and that makes the weather record a practical reference for understanding the load this equipment carries.
