A contractor called out to repair a heat pump here has to settle one question before anything else: whether a worn component gave out under accumulated weather stress or simply reached the end of its service life. 188 severe weather events were recorded in Summit County, Ohio between 2015 and 2024. At that rate, severe weather is a standing condition in this county, not an occasional event, and that shapes what a contractor checks first. Capacitors, contactors, and refrigerant connections all carry the load when the system is pushed hard by outside conditions, and a failed part in each of those categories tells a different repair story depending on what drove the failure.
Compressor contacts corrode in ways that reflect what the system has been asked to do across its service life, and refrigerant circuits develop faults that are specific to how and when a particular unit was installed. Half the homes in Summit County, Ohio were built in 1966 or earlier (2020-2024 ACS 5-year). That depth of housing history means the heat pumps running in these homes have been swapped out and adapted over the decades, and each generation of replacement leaves its own failure modes behind. When a contractor opens a unit here, the repair scope comes down to what the internals actually show and whether the parts that system takes are still in production.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil, which together do most of the system's heavy lifting. When a heat pump stops heating or cooling, the compressor is one of the first things a contractor looks at, along with the condenser coil and the fan motor that pulls air across it.
Inside the house, the air handler contains the blower motor and the evaporator coil, which conditions the air before it moves into the living space. The refrigerant lines connecting both units, the expansion valve that regulates refrigerant flow, and the reversing valve that switches the system between heating and cooling are all points a contractor will examine when the system is not performing right.
The drawing shows the general layout of a heat pump system, and a licensed contractor will determine which components are relevant to your specific home and situation.
