A heat pump running through a cold Kansas winter asks the most of its compressor and reversing valve, and both parts show that history when a contractor opens the system for a repair call. Homes in Rooks County, KS run heat about eight months a year, from October through May. Capacity drops as outdoor temperatures fall, so the compressor is working hardest at exactly the point when the season still has months left to run. By the time a homeowner notices a problem, the reversing valve, the defrost board, and the refrigerant circuit have already carried a full seasonal load. A contractor diagnosing a failure here checks those components first, because they are where the wear lands.

Ductwork laid in for an earlier generation of heating does not reshape itself when the equipment changes. Half the homes in Rooks County, Kansas were built in 1953 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump in stock like this finds refrigerant lines, air handlers, and return paths that were retrofitted into spaces built for something else, and what that retrofit left behind is what decides how the repair goes. A worn contactor or a failed reversing valve is a parts job. Ductwork that was never sized for a heat pump's airflow is a different conversation, and it surfaces the moment a contractor pulls the covers.
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 condenser coil. The compressor is where most faults show up first. When it labors or fails, the system stops moving heat altogether. The condenser coil, which wraps around the inside of that cabinet, is where the outdoor fan pulls air through.
Inside the house, the air handler contains the evaporator coil and the blower fan that pushes conditioned air through the home. The reversing valve, which sits in the refrigerant line and tells the system whether to heat or cool, is a common repair target. The two units are tied together by refrigerant lines that run between them and by a thermostat that sends the signals.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific system and home.

Weather in this part of Kansas puts real demands on heat pump equipment, cycling it hard through whatever conditions arrive. How often those conditions turn severe is a local fact, and it shapes how much repair work the equipment here actually sees.
