A heat pump failing in Union County has probably not been pushed hard by the weather. 68 severe weather events were recorded in Union County, Ohio between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a steady grind on components. A contractor quoting a repair should look first at refrigerant condition, contactor wear, and coil cleanliness, because those degrade on their own schedule regardless of what the sky does. The weather record in this county is real but light enough that blaming it for a failed compressor or a seized fan motor would skip past the likelier answers.
Heat pump systems in houses of this vintage are old enough that parts availability shapes the repair more than the labor does. Half the homes in Union County, Ohio were built in 1996 or earlier (2020-2024 ACS 5-year). A contractor who opens a unit and identifies the failed component still has to confirm that component ships. If it does not, the repair scope changes on the spot, and what looked like a straightforward fix becomes a conversation about what is actually serviceable. That is the variable that decides how a repair job in this county goes.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and the outdoor coil. These two components are where most failures show up. A bad compressor means the system moves no heat at all; a damaged or fouled coil means it moves heat poorly, and a contractor will put eyes on both early.
Inside, the air handler or indoor coil sits in a mechanical closet, attic, or basement and is where the conditioned air actually enters the home. The reversing valve, which tells the system whether to heat or cool, and the expansion valve, which controls refrigerant flow, are also common trouble spots a contractor will test.
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.
