A heat pump that is struggling in Crawford County has probably not been worn down by relentless weather. 43 severe weather events were recorded in Crawford County, Michigan between 2015 and 2024. At that rate, severe weather is an event rather than a condition, and it leaves little mark on the diagnostic picture. A contractor here will open the system looking at compressor age, refrigerant condition, and how consistently the equipment has been serviced, because those are what explain most of what goes wrong in an area where the weather seldom pushes systems to their limit.
Housing stock built for one generation of equipment and retrofitted for another tends to carry layered electrical work, and a heat pump sitting inside that history may have been the second or third system in that house. Half the homes in Crawford County, Michigan were built in 1980 or earlier (2020-2024 ACS 5-year). That is the pool a repair call draws from: a unit that may run on wiring touched by different hands over decades, where the connections a contractor finds when the cover comes off are not always what the original install card describes. Whether a part is still made for that unit, and whether the circuit feeding it is sound, are the two questions that determine what the repair actually costs.
The Parts of a Heat Pump a Contractor Checks During Repair
The outdoor unit is usually where a contractor starts. It houses the compressor, which is the component doing the hardest work, and the coil that exchanges heat with the outside air. When either of those fails, the system stops moving heat altogether. The refrigerant lines running between the two units are checked at the same time, since a leak there will starve the whole system.
Inside the house, the air handler holds the indoor coil and the blower fan that pulls air across it. A contractor also checks the reversing valve, which sits in the outdoor unit and tells the system which direction to run. The thermostat and the capacitors that start the motors round out what gets examined, since small electrical components fail before the larger mechanical ones do.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which parts and conditions apply to your specific home.

Severe Weather Events in Crawford County by Year
Extreme weather puts heat pumps under load at the exact moments they are least able to shed wear quietly. How often that happens here shapes how hard the equipment works and how soon repair needs show up.
