Step 1 of 3: Equipment

A contractor diagnosing a heat pump repair in Holmes County has to establish what the system has actually been running against before settling on a cause. 64 severe weather events were recorded in Holmes County, Ohio between 2015 and 2024. At that rate, severe weather is a periodic presence here, not a relentless one. A compressor that failed in this county likely did so because of age or deferred maintenance rather than cumulative storm load, and a good contractor checks refrigerant levels, electrical connections, and wear on moving parts before attributing anything to the weather.

A heat pump running in a house this old has probably been through at least one refrigerant transition, and the components inside it reflect that history. Half the homes in Holmes County, Ohio were built in 1986 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, the question that shapes the repair is whether the parts it needs are still in production. If they are not, the scope of the job changes before any labor is priced. Ductwork and wiring are separate questions; what drives the outcome in stock of this vintage is supply availability for the specific system already installed.

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 are the two pieces that do the heaviest work. When a heat pump stops heating or cooling, a contractor starts here. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in this cabinet are among the first things they rule in or out.

Inside the house, the air handler contains the indoor coil and the blower fan that moves conditioned air through the home. The reversing valve, which switches the system between heating and cooling, sits in the outdoor unit and is a common point of failure when a heat pump runs in only one mode. The expansion valve and refrigerant lines that connect both units are also on a contractor's checklist.

The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components and conditions apply to your specific house.
