A contractor quoting a heat pump repair in Ottawa County has to decide early what actually wore the system down. 61 severe weather events were recorded in Ottawa County, Michigan between 2015 and 2024. At that rate, severe weather here is an occasional event, and a compressor or reversing valve that has given out is rarely carrying storm damage as its explanation. What a contractor finds when they open the unit tends to point instead toward how old the equipment is, whether refrigerant levels have been kept up, and whether the install was done right to begin with. Those are the variables that drive the repair scope here.
Heat pump repair in housing this old turns quickly on one question: whether the part a system needs is still being made. Half the homes in Ottawa County, Michigan were built in 1988 or earlier (2020-2024 ACS 5-year). Equipment running in stock that age has often been replaced at least once since the house was built, and what is running now is old enough that a contractor opening a failed unit may be looking at components a distributor carries only on backorder, or not at all. That reality shapes the repair scope before labor or diagnosis enters the conversation.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually what a homeowner notices first, sitting on a pad beside the house. It holds the compressor and the outdoor coil, and when either one fails, the system stops moving heat in or out. The compressor is where most repair calls start.
Inside the house, the air handler contains the indoor coil and the blower, which pushes conditioned air through the home. The reversing valve sits within the system and tells it which direction to run. The expansion valve, refrigerant lines, and the thermostat that controls the whole sequence are all points a contractor checks when the outdoor and indoor units appear sound.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific system and what work each one needs.
