A heat pump failing in Harrison County is rarely a weather story. 69 severe weather events were recorded in Harrison County, Ohio between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, and a contractor diagnosing a refrigerant leak or a compressor that won't start is looking past the weather calendar almost immediately. What they are checking is the age of the unit, how well it was installed, and whether the coils and filters have been serviced. Those three factors explain the overwhelming majority of what breaks in this county, and a repair quote that blames storm exposure is almost certainly pointing at the wrong cause.
Half the homes in Harrison County, Ohio were built in 1964 or earlier (2020-2024 ACS 5-year). A house built that long ago has almost certainly seen more than one heating and cooling system come and go inside it. What that means for repair work is specific: when a contractor opens a heat pump in a house from this part of the stock, the components inside reflect years of incremental replacement, and some of what they find will take parts that are no longer stocked locally. A repair that quotes quickly at the door can stall once the unit is open and the actual part numbers are known.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit holds the compressor and the condenser coil, and it sits on a pad outside the house. The compressor is the part contractors go to first: when it labors or fails, the system loses its ability to move heat in either direction. The condenser coil surrounds it, and damage or heavy fouling there shows up as reduced output.
Inside the house, the air handler contains the evaporator coil and the blower, and it pushes conditioned air through the home. The reversing valve, which lives in the outdoor unit, is what lets a heat pump heat and cool, so a valve that sticks becomes a straight diagnostic target. The expansion device and the refrigerant lines connect both ends, and a contractor checks them for leaks or restriction when the obvious pieces test clean.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what service is needed in your specific home.
