A contractor called out to repair a heat pump in Ohio County has to establish what actually drove the failure before they can price the job or recommend a fix. 87 severe weather events were recorded in Ohio County, Kentucky between 2015 and 2024. That record means the equipment here has seen real weather load over the years, enough that a contractor checks weather-exposed components carefully. But it also means age and maintenance gaps are just as likely to explain a failed reversing valve or a compressor that has quit, and a competent diagnosis treats those as equal candidates rather than reaching for the weather first.
Refrigerant lines corrode, electrical connections loosen, and capacitors degrade on a schedule set by how long a system has been running in a house that has asked a lot of it. Half the homes in Ohio County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). That means a contractor opening a heat pump here is likely to find wear inside the unit that is not random failure but the product of sustained use in housing whose mechanical systems are carrying their age. A part that still functions at inspection may be close enough to failure that replacing it mid-job, not in a separate visit, is the call a contractor has to make on the spot.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize, a metal cabinet that sits on a pad beside the house and holds the compressor and the outdoor coil. The compressor is the part contractors reach for first when a heat pump stops moving heat altogether, and the coil is what they examine when the system runs but struggles. Inside, the air handler holds the indoor coil and the blower fan, and faults there tend to show up as poor airflow or temperature swings at the vents.
The reversing valve is the piece that makes a heat pump different from a straight air conditioner, and a failed valve is often why a system heats in summer or cools in winter when it should be doing the opposite. The expansion valve sits inside the refrigerant circuit and controls pressure between the two coils. A contractor also checks the refrigerant lines that connect the outdoor and indoor units, looking for damage, ice buildup, or signs of a leak.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what service each one needs in your specific home.
