Homes in Lea County, NM run heat about six months a year, from November through April. The refrigerant circuit works hard across a heating season that long, and the reversing valve, which switches the system between heating and cooling modes, cycles every time the season changes. On a repair call, a contractor checks those components first, because they carry the most accumulated wear. Coil condition and refrigerant charge tell the clearest story about how the system has held up.
Ductwork and wiring put in for one generation of equipment carry the marks of every system that has run through them since. Half the homes in Lea County, New Mexico were built in 1979 or earlier (2020-2024 ACS 5-year). By the time a contractor opens the equipment on a repair call, the question of what parts the system actually takes gets complicated by prior work: spliced wiring, non-original fittings, or components swapped in during a previous repair that do not match the current unit's spec. A quote that looked simple before the panels came off can change once the contractor sees what is actually connected to what.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house and holds the compressor and condenser coil. The compressor is where most repair calls start. When it fails, the system runs but moves no heat. The condenser coil sits around it, and a damaged or dirty coil sends strain back to the compressor.
Inside, the air handler contains the evaporator coil and the blower that moves air across it. The expansion valve sits between the two coils and controls refrigerant flow. A refrigerant line set runs between the outdoor unit and the air handler, and the reversing valve inside the outdoor unit is what lets the system heat instead of cool.
The drawing shows a general layout of these components, and a licensed contractor determines what applies to your specific house and system.

What Lea County, New Mexico Requires for HVAC Repair
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 Lea County
Weather puts direct load on heat pump equipment: temperature swings, humidity shifts, and storm activity all affect how hard a system works and how fast wear accumulates. In Lea County, that workload shapes what repair needs look like and what a local contractor is called out to fix.
