A heat pump running heat loses capacity as outdoor temperatures fall, and Lander County's winters push that deficit hard. Homes in Lander County, NV run heat about nine months a year, from September through May. The reversing valve cycles every time the system switches modes, and after enough heating seasons in this climate it is one of the first components to develop faults. Refrigerant charge also shifts with sustained cold-weather operation, so a contractor diagnosing a repair here checks the circuit before assuming the compressor itself is the problem.
Ductwork in a house this old was not laid for the equipment now inside it. Whatever runs in the system today was fitted into an infrastructure that predates it, and the seams, joints, and connections in that ductwork have been asked to serve more than one generation of hardware. Half the homes in Lander County, Nevada were built in 1986 or earlier (2020-2024 ACS 5-year). When a refrigerant line shows stress or a compressor opens with wear the homeowner did not expect, the retrofitted path that air and refrigerant have traveled through is part of what a contractor reads to understand why. Parts availability for the current unit is the other variable a contractor settles before committing to a repair scope.
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 one of the coils. The compressor is where most repair calls start. When it labors, shorts, or stops moving refrigerant, the whole system follows. The coil wrapped around it is the next place a contractor looks, since bent fins or frost buildup block the heat exchange the system depends on.
Inside the house, the air handler holds a second coil and the blower that moves conditioned air through the home. A refrigerant line set runs between the two units, and a reversing valve inside the system switches the direction of flow between heating and cooling. The blower motor, the valve, and the line connections are all places a contractor checks when the system runs but does not perform.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house and system.

Severe Weather Events in Lander County
Extreme weather puts real strain on heat pump systems, which have to work harder and cycle more often when conditions turn harsh. How much strain depends on local patterns, and Lander County has its own record.
