Ten months of the year, your system is working
Only two months here ask nothing of your furnace or your air conditioner. Heat runs November through March, when nights average 31°F. Cooling runs May through September, with afternoons averaging 94°F. That is ten months of the year one system or the other is carrying the load, and a system sized wrong for either season will struggle for most of the year, not just a few weeks of it.
More than half of homes here heat with electricity, so a winter storm that knocks out power can knock out heat at the same time. Eddy County has seen 11 winter storms and 222 damaging wind events over the past ten years, and statewide, 13% of households lost power for at least a day in 2024. A new system is worth planning around that, not just around the thermostat setting.

New Mexico requires HVAC contractors to hold a state license.
The Construction Industries Division tests and licenses HVAC contractors across New Mexico, including Eddy County. The license belongs to the contractor, not to any one job, so it tells you this person or company met the state's requirements before they ever set foot in your home, not that this particular installation was checked as it went.
That license covers who is allowed to do the work. What happens on your property still runs through the local building office. In most cities and counties, installing a heating and cooling system needs a permit, with an inspection once the work is done. That inspection is what checks the gas connections, the wiring and the refrigerant lines, separate from whatever the state license already vouched for.

- When should I replace my HVAC system?
- Replace it when repairs stop being worth it, not just when it breaks. An old furnace or air conditioner that needs a repair every year, or that can't heat or cool the house evenly, is telling you something. Here winters average 31°F and summers average 94°F, and the system runs 10 months out of the year between the two seasons, so there isn't much slack time when a weak unit can just coast. If a contractor is telling you the same part keeps failing, that's usually the sign to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to do both together. A furnace and air conditioner installed at the same time were sized and matched to work as a pair, and replacing one now and the other in a few years means mixing an old blower or coil with new equipment that wasn't designed around it. It also means paying for a second installation visit down the road instead of one. A contractor can look at the age and condition of both and tell you whether it's worth waiting on one or doing them together.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, then connects it to the ducts, refrigerant lines, electrical, and venting. They'll check that the ductwork is sized right for the new unit and seal up any connections. In most cities and counties around Carlsbad, this job needs a permit from the local building office, and an inspector checks the work once it's done. New Mexico also requires the contractor doing the work to hold a state HVAC license through the Construction Industries Division.
