On a heat pump repair call in Cass County, a contractor works backward from what the refrigerant circuit and reversing valve have already been through. Homes in Cass County, NE run heat about eight months a year, from October through May. Heating mode is where a heat pump works hardest: outdoor coil efficiency drops as temperatures fall, and the compressor cycles more frequently to hold indoor setpoints. That repeated stress concentrates wear on the reversing valve, the defrost board, and the low-side refrigerant circuit long before a compressor shows obvious signs. A contractor diagnosing a failed heat pump here checks those components first, because that is where the heating load lands.
Ductwork laid down for a furnace and a central air conditioner was built to move air differently than a heat pump asks it to. When a contractor pulls a heat pump apart for repair, the opened system often points to sealing gaps, undersized runs, or flex connections that were never right for this kind of load. Half the homes in Cass County, Nebraska were built in 1977 or earlier (2020-2024 ACS 5-year). That puts the ductwork, and not just the refrigerant circuit, on the diagnostic list whenever a heat pump here is losing capacity or cycling hard.
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. These are the first places a contractor looks when a heat pump stops heating or cooling properly. A failed compressor, a refrigerant leak at the coil, or a seized fan motor in that cabinet will each kill the system in its own way.
Inside the house, the air handler moves conditioned air through the home and contains the evaporator coil and the blower motor. The reversing valve, which sits in the refrigerant line and tells the system which direction to run, is another part a contractor tests when the unit runs but delivers the wrong temperature.
The drawing shows a typical heat pump layout, and a licensed contractor determines which components apply to the specific system in your home.

Severe Weather Events in Cass County
Heat pumps work hardest when the weather outside pushes hardest against them, and that steady pressure is what shortens the life of components and drives repair calls. Cass County's weather record is part of why heat pump maintenance is a local conversation, not a generic one.
