A heat pump repair in McHenry County starts with the compressor and the reversing valve, because those are the parts that have been working. Homes in McHenry County, ND run heat about nine months a year, from September through May. Capacity drops as outdoor temperatures fall, which means the compressor cycles harder through the coldest months, not just longer. A contractor pricing a repair here checks the refrigerant circuit and the reversing valve before quoting anything else, because that accumulated load is where failures concentrate. Coil condition follows close behind.
Ductwork and refrigerant lines in stock this old were fitted to whatever ran first, then adapted, then adapted again. Half the homes in McHenry County, North Dakota were built in 1966 or earlier (2020-2024 ACS 5-year). A heat pump that has lived through that chain of changes can present a contractor with components whose replacement parts are no longer manufactured, or are sourced from a shrinking pool of suppliers. That changes what the repair bill looks like and sometimes what the repair is.
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 the outdoor coil. The compressor is where a contractor starts when a heat pump stops moving heat properly, because it does the core mechanical work of the system. The outdoor coil, the fan above it, and the refrigerant lines running into the house are each examined in turn.
Inside the house, the air handler pulls indoor air across an indoor coil and pushes conditioned air into the living space. The reversing valve, which sits inside the refrigerant circuit, is what allows the system to shift between heating and cooling, and it is a common point of failure when a heat pump gets stuck in one mode. The expansion valve and the refrigerant charge are also part of what a contractor reviews.
The drawing shows a typical layout, and a licensed contractor determines which parts apply to the specific system in your house.
