A contractor called out to repair a heat pump in Lorain County starts with the compressor and reversing valve because those are the components that absorb the most stress when a system has been cycling hard through repeated weather events year after year. 148 severe weather events were recorded in Lorain County, Ohio between 2015 and 2024. At that rate, severe weather is part of normal operating life for equipment in this area, and a compressor that has been pushing through that load regularly will show wear in the windings and valve seats before it shows up anywhere else. Age alone does not account for what a contractor finds here.
A heat pump sitting in a house built for a different era carries a specific kind of wear. Half the homes in Lorain County, Ohio were built in 1973 or earlier (2020-2024 ACS 5-year). That age of housing stock means ductwork has had a long time to develop leaks, lose its seal at joints, and shift in ways that put extra load on the refrigeration system itself. When a contractor opens the unit, what they find, coil condition, refrigerant charge, compressor wear, reflects how hard the equipment has been working to make up for what the house around it was losing. The repair scope follows from that, not from the year on the permit.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits on a pad beside the house and holds the compressor and condenser coil. These are the pieces a contractor reaches first when a heat pump stops heating or cooling properly. A failed compressor, a refrigerant leak at the coil, or a seized contactor in that cabinet are among the most common sources of a breakdown.
Inside the house, the air handler holds the evaporator coil and the blower fan that moves conditioned air through your home. The refrigerant lines run between the two units, and the reversing valve inside the system is what lets a heat pump shift between heating and cooling modes. When the system blows the wrong temperature or runs but does nothing, the reversing valve and the expansion device are where a contractor looks next.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply to your specific house and situation.
