A heat pump in Lauderdale County has been running against conditions that most equipment elsewhere never sees at anything close to this rate. 700 severe weather events were recorded in Lauderdale County, Alabama between 2015 and 2024. At that frequency, stress accumulates in the components that work hardest under load: capacitors, compressor windings, contactors. A contractor quoting a repair here checks those parts first, because the county's weather history makes stress-related failure the more likely cause, and working backward from that saves time on the diagnosis.

Ductwork in a house this old has absorbed a long working life of repairs, retrofits, and seasonal stress, and a refrigerant leak or a failed reversing valve is only the first thing a contractor opens. Half the homes in Lauderdale County, Alabama were built in 1980 or earlier (2020-2024 ACS 5-year). That history means a heat pump running in stock like this may be drawing on parts that manufacturers have phased out or are running thin, and what the opened system contains decides whether a repair is a parts swap or a search. Availability, not labor, is where the job stalls.
The Parts of a Heat Pump a Contractor Checks During Repair

The outdoor unit is usually where a contractor starts. It houses the compressor, which drives the whole system, and the outdoor coil, which either pulls heat from the air or releases it depending on the season. A failed compressor or a damaged coil will stop the system from conditioning the air at all.
Inside the house, the air handler holds the indoor coil and the blower fan that moves conditioned air through the home. The refrigerant lines connecting the two units run between them, and the reversing valve inside the system is what lets a heat pump shift between heating and cooling. Any of these can be the source of a problem.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your particular house and situation.
