A contractor quoting heat pump repair in Morrow County is working out why this particular system failed, and the area's weather history tells only part of that story. 43 severe weather events were recorded in Morrow County, Ohio between 2015 and 2024. At that rate, severe weather is a periodic event here, not the kind of relentless seasonal load that grinds down compressors and reversing valves on its own. A system showing refrigerant loss, a seized compressor, or a failed capacitor is far more likely carrying the weight of its age and how well it was installed than of weather accumulation. That is where a contractor looks first.
A heat pump sitting in a house built for something else entirely has usually been serviced more than once, and what the opened system contains reflects that layered history. Half the homes in Morrow County, Ohio were built in 1980 or earlier (2020-2024 ACS 5-year). By the time a contractor pulls a faulty reversing valve or a failed defrost board on a unit in stock like this, the question is whether the manufacturer or an aftermarket supplier still makes that part at all, and in what condition the system was kept between services. An older house that has cycled through more than one heating technology can produce a repair where the labor is straightforward and the parts sourcing is not.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house on a pad or bracket and holds the compressor and the outdoor coil. The compressor is where most repair calls start. When it labors, rattles, or stops running, the whole system loses its ability to move heat in either direction. The outdoor coil wraps around it and is the next place a contractor looks when output drops.
Inside the house, the air handler contains the indoor coil and the blower fan, which pulls air across the coil and pushes it through the home. The reversing valve, housed in the outdoor unit, is what lets the system heat in winter and cool in summer. A failed reversing valve is a common reason a heat pump blows only lukewarm air in one season.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what work they require.
