Cold outdoor air is where a heat pump earns its failures. Capacity drops as temperatures fall, and the compressor and reversing valve cycle harder during heating than during any cooling demand the summer puts on them. Homes in Pottawatomie County, KS run heat about seven months a year, from October through April. A contractor diagnosing a heat pump here checks those components first, because that is where accumulated wear shows up: sluggish reversing, refrigerant drawn low, a compressor pulling high amperage before it finally quits. Back-up heat strips get examined too, since a heat pump leaning on them to cover its own capacity loss runs up bills before anything looks obviously broken.

Half the homes in Pottawatomie County, Kansas were built in 1987 or earlier (2020-2024 ACS 5-year). A heat pump sitting in a house that old has almost certainly been replaced at least once, but the refrigerant lines, the air handler connections, and the electrical feeds it depends on may not have been. When a contractor opens a failed unit here, the first real question is whether the components it needs are still manufactured and whether the existing infrastructure it is wired into will accept a current replacement part without modification. That is where the repair scope either stays straightforward or grows.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits outside the house and holds the compressor and the condenser coil. The compressor is where most repairs start. When a heat pump stops moving heat in either direction, a contractor will open that cabinet first and test what is happening inside it.
The air handler sits indoors, usually in a utility closet or attic, and contains the blower motor and the evaporator coil. The reversing valve, which lives in the outdoor unit, is what lets the system run in both heating and cooling modes. A failed reversing valve is a common reason a heat pump heats but will not cool, or the other way around. The thermostat and the refrigerant lines that connect both units are also part of what a contractor traces when the symptom does not point to a single piece right away.

Extreme weather puts heat pumps under load they were not sized to handle on a calm day. How hard the equipment works in Pottawatomie County is a local fact, and that makes repair needs here different from those in quieter climates.
