A heat pump doing repair work in Eddy County has already been cycling through real winter temperatures, not just light shoulder-season runs. Homes in Eddy County, NM run heat about five months a year, from November through March. The compressor works hardest when outdoor temperatures drop, and the reversing valve switches the refrigerant circuit every time the system changes modes. A contractor diagnosing a fault here starts with those two components because they carry the bulk of the seasonal load. Refrigerant charge and coil condition follow, since low charge cuts heating capacity sharply on cold days.

Ductwork sized and run for older equipment shapes what a contractor finds when they open a heat pump in this county. Half the homes in Eddy County, New Mexico were built in 1980 or earlier (2020-2024 ACS 5-year). That history means the refrigerant circuit, the controls board, and the reversing valve may all belong to a product line that has since been discontinued, and a repair depends on whether the required parts still exist in a supply chain. A contractor who pulls a failed component here does not always find a current replacement waiting.
The Parts of a Heat Pump a Contractor Checks First

The outdoor unit sits on a pad outside the house and holds the compressor and the condenser coil. These are where most faults show up. A failing compressor may not move refrigerant at all, while a damaged coil can cause the system to lose pressure or freeze over.
Inside, the air handler contains the evaporator coil and the blower fan, which push conditioned air into the living space. The reversing valve, also inside the refrigerant loop, is the part that lets the system heat as well as cool. A contractor checks both when the system runs in one mode but not the other.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to the specific equipment and configuration in your house.

Licensing Rules for HVAC Repair in Eddy County, New Mexico
New Mexico’s contractor licence does not reach casual, minor or inconsequential work taken one project at a time and totalling no more than seven thousand two hundred dollars ($7,200) a year — but the exemption has to be declared to the division, it is not automatic.
New Mexico requires a contractor licence classified for the work being done: no person may act as a contractor without one, and mechanical work falls to the division’s mechanical bureau.
Severe Weather Events in Eddy County
Eddy County's climate puts heat pumps under real stress, and stress shortens equipment life and drives repair calls. How hard a system has worked is a local fact, and the weather record is part of that picture.
