Takes about a minute. No obligation.
Homes in Chaves County, NM run heat about seven months a year, from October through April. A heat pump here runs its compressor hard through the cold half of the year, cycling it repeatedly as outdoor temperatures drop and the unit works harder to pull heat from colder air. That sustained load accumulates on the compressor, the reversing valve, and the refrigerant circuit in ways that shorter heating climates do not produce. When a contractor arrives for a repair call, those are the components they open first, because the heating season load gives them the most reason to fail.
Ductwork laid in before today's heat pumps existed was sized and routed for whatever the original system needed, and that original system is gone. Half the homes in Chaves County, New Mexico were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor opening a heat pump here has to look at what the ducts actually carry, where they leak, and whether the return air path delivers enough volume for the equipment in place now. A refrigerant charge or a failed board might look like the whole job until the duct system turns out to be why the repair keeps coming back.
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 the condenser coil. These are the first pieces a contractor looks at, because a failed compressor or a damaged coil will stop the whole system. The air handler lives inside, usually in a closet or utility space, and moves conditioned air through the home.
The reversing valve sits inside the outdoor unit and is what lets a heat pump both heat and cool. The refrigerant lines run between the two units, and the expansion valve controls how refrigerant moves through the coil. A contractor checks the refrigerant charge, the electrical connections at both units, and the thermostat that tells the system what to do.
The drawing shows the general layout of a heat pump system, and a licensed contractor determines which components apply and what work is needed in your specific home.

Licensing and Legal Requirements in Chaves 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 Chaves County
Extreme weather puts heat pumps under load they were not sized to ignore, and repeated stress is what turns a small fault into a failed component. How often that pressure arrives in Chaves County is a local fact, and it shapes what repair work looks like here.
