A contractor quoting heat pump repair in Dickinson County starts by working out what the system has already been through. 108 severe weather events were recorded in Dickinson County, Michigan between 2015 and 2024. At that rate, severe weather is a standing part of the operating life of equipment here, not an occasional interruption to it. That matters because refrigerant lines, capacitors, and contactors that have been stressed repeatedly by weather events can look like they failed randomly when they did not. A contractor who skips that history may replace a part and leave the underlying load damage in place.
Ductwork and wiring in a house of this age were installed for whatever system ran before the current one, but that is an installation question. For repair work, what matters is what a contractor finds once the heat pump is open. Half the homes in Dickinson County, Michigan were built in 1970 or earlier (2020-2024 ACS 5-year). That gap between the building and the equipment running in it means the components inside a system here have often been through retrofits, adaptations, or prior repairs that leave the internals looking different from a clean factory configuration. A contractor pulling a failed part has to confirm what is actually in the unit before ordering anything, because the spec on the label and the spec of what was fitted may not match.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is usually what draws attention first, and it is where a contractor starts. That cabinet houses the compressor, which does the heavy lifting of the whole system, along with the condenser coil and a fan that moves air across it. When either of those components fails, the system loses its ability to do its job entirely.
Inside the house, the air handler holds the blower motor and the evaporator coil, and it is responsible for moving conditioned air into the living space. Connecting the two units is the refrigerant line set, and alongside the air handler sits the reversing valve, which is the part that lets the system run in both directions depending on the season. The expansion valve and the refrigerant charge itself are also points a contractor examines when the system is underperforming.
The drawing shows a typical layout, and a licensed contractor determines which components and conditions apply to your specific home.
