A heat pump in Cheboygan County that needs repair has most likely been worn down by time and use, not by what the weather threw at it. 42 severe weather events were recorded in Cheboygan County, Michigan between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition, and it does not explain a failed reversing valve or a refrigerant leak the way accumulated run-hours or a missed service interval does. A contractor quoting a repair in this area will check the age of the compressor and the condition of electrical contacts before pointing at the storm record.
Refrigerant lines, electrical connections, and contactors in a house this old have gone through more heating and cooling seasons than the equipment's design accounts for. Half the homes in Cheboygan County, Michigan were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock like this finds wear that compounds: corroded terminals, weakened capacitors, and refrigerant fittings that have been stressed by years of pressure cycling. Parts availability matters too, because older equipment sometimes takes components that are no longer stocked locally. The repair scope is set by what the opened system actually contains, not by the age on the permit.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house on a pad or brackets and holds the compressor and condenser coil. The compressor is where most repairs begin. When it fails, the system runs but moves no heat. The condenser coil surrounds it, and a bent or dirty coil forces the compressor to work harder than it should.
The air handler lives inside the house, usually in a utility closet, basement, or attic, and it contains the blower motor and the evaporator coil. The expansion valve and the refrigerant lines connect the two units. The reversing valve, which sits inside the outdoor unit, is the part that lets a heat pump both heat and cool, and a stuck reversing valve is a common reason a system works in one mode but not the other.
The drawing shows a typical layout, and a licensed contractor determines which of these parts apply to your specific system and what condition each one is in.

Severe Weather Events in Cheboygan County, Year by Year
Extreme weather puts heat pumps under stress they were not sized to run through continuously, and repeated stress is where repair needs start. How hard the weather pushes on equipment here is a local fact, and it shapes what a contractor in Cheboygan County sees in the field.
