Takes about a minute. No obligation.
A heat pump here carries a real heating load. Homes in Quay County, NM run heat about seven months a year, from October through April. That stretch of sustained cold cycling stresses the reversing valve hard, because the valve switches states every time the system moves between heating and defrost mode, and a long heating season means it switches often. Coil connections and refrigerant lines accumulate wear on the heating side specifically. A contractor diagnosing a repair here checks those components first, before looking at anything tied to summer cooling.
Ductwork in a house this old has been carrying air through connections that were sealed, resealed, and sometimes just left. When a contractor opens a heat pump here, the refrigerant lines, coil condition, and electrical terminations reflect a service history that is usually thinner than the age of the system suggests. Half the homes in Quay County, New Mexico were built in 1966 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and how its mechanical systems have been maintained is what turns a straightforward repair into a longer parts conversation. A component that looks like the problem on arrival is often covering a second one.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit sits outside the house on a concrete pad or wall bracket and holds the compressor and the outdoor coil. These are where most repair calls start. A failing compressor runs loud or not at all; a damaged coil loses the ability to exchange heat with the air around it.
Inside the house, the air handler moves conditioned air through the home and holds the indoor coil and the blower motor. The reversing valve, which sits inside the outdoor unit, is what lets the system heat in winter and cool in summer, and it is a common point of failure when the system blows the wrong temperature.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system and what work each one needs.

Licensing and Legal Requirements in Quay 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 Quay County
Extreme weather puts direct stress on heat pump components, cycling them harder and more often than calm conditions do. How much of that a system has absorbed over the years shapes what a repair technician finds when they open it up.
