A heat pump that stops heating or cooling reliably in Butler County has almost certainly worn out from age or uneven maintenance, not from weather load. 57 severe weather events were recorded in Butler County, Alabama between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition, and a contractor arriving at a repair call knows the outdoor unit and refrigerant circuit have not been pushed especially hard by the climate. What they look for instead is compressor wear, refrigerant loss from fittings that were never quite right, or a reversing valve that has simply cycled past its service life.
Heat pumps running in houses this old have typically outlasted the original equipment that replaced the original equipment. Half the homes in Butler County, Alabama were built in 1979 or earlier (2020-2024 ACS 5-year). That layering matters when a contractor opens a unit: what they find may be a refrigerant line set or a coil from a different generation than the air handler beside it, and the parts a mixed system takes are not always in active supply. A contractor pricing a repair here has to confirm what is actually inside before a parts search makes any sense.
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 moves refrigerant through the system, and the condenser coil, which releases or absorbs heat depending on the season. When either one fails, the whole system stops doing its job. The refrigerant lines running between the outdoor and indoor units are checked alongside them, since a leak there affects everything else.
Inside the house, the air handler holds the evaporator coil and the blower fan. The coil transfers heat to or from the air passing over it, and the fan pushes that air through the home. The reversing valve, which sits in the outdoor unit, is the part that lets a heat pump switch between heating and cooling. A contractor checks it when the system runs but delivers the wrong kind of air.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts apply and what needs attention in your specific home.
