A contractor called out to repair a heat pump here starts with the machine's service history, not the weather outside. 77 severe weather events were recorded in Lawrence County, Kentucky between 2015 and 2024. At that rate, severe weather is an occasional event in this county, and a failed compressor or a refrigerant problem is far more likely to trace back to years of deferred maintenance or an aging component than to storm load. A contractor will check wear on the reversing valve, the condition of the coil, and how long the system has been running without service.
Ductwork laid down for a different era of heating runs through a house long before any heat pump arrived in it. Half the homes in Lawrence County, Kentucky were built in 1989 or earlier (2020-2024 ACS 5-year). A contractor pulling a heat pump apart in Lawrence County is working on equipment that was retrofitted into an existing shell, and the refrigerant valves, reversing valves, and electrical connections that fail first in stock like this are often the ones that were stressed from the start by that mismatch. Replacement parts for a system of this vintage can be scarce, and that scarcity is what turns a straightforward repair into a longer conversation about what the opened unit actually requires.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a concrete pad beside the house and holds the compressor, which is the part contractors go to first when a heat pump stops moving heat the way it should. The coil wrapped around the inside of that cabinet and the fan that pulls air through it are checked alongside it, since a fault in any one of them shows up as the same symptom.
Inside the house, the air handler hangs in a utility closet, attic, or basement and holds a second coil along with the blower that pushes conditioned air into the home. The reversing valve, which sits inside the outdoor unit, tells the system which direction to run, and a failed valve is a common reason a heat pump heats in summer or cools in winter. The refrigerant lines that run between the two units and the capacitors that start each motor are also on a contractor's checklist.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and situation.
