Grants asks a furnace to run eight months a year
Homes here need heat from October through May, eight months of the year. Winter nights average 18°F from December through February, so the furnace put in now has to carry the house through a long, cold stretch, not just a few hard weeks.
Any new gas furnace sold today has to reach at least 80 percent AFUE, so most of what burns turns into heat instead of going up the flue. Cibola County has also logged 36 winter storms and 89 damaging wind events over the past ten years, and across New Mexico, 13 percent of households lost power for at least a day in 2024. A furnace that comes back on by itself once the power does matters here.

A high-efficiency gas furnace would save about $70 a year to run in Cibola County compared with a gas furnace.

New Mexico requires HVAC contractors to hold a state license.
The Construction Industries Division licenses the contractor, not the furnace install itself. That means the company doing the work has been tested by the state and is on record there, but the license does not cover what happens on this particular job in your home.
That comes from the local building office instead. Replacing a furnace needs a permit in most cities and counties, and an inspection once the work is done. For a gas furnace, that inspection matters because a bad gas connection is where things go wrong. In Cibola County, 42.2% of homes heat with gas, and the permit and inspection are what check this job, not the license.

- What size furnace does my house need?
- There's no single number that works for every house. A contractor sizes it with a load calculation that looks at your square footage, insulation, window count, and ceiling height, then weighs that against nights that average 18°F here. Guessing high seems safe but it isn't. An oversized furnace cycles on and off fast and never runs long enough to heat evenly, while one sized right will run longer, steadier stretches and last longer doing it.
- How do I know it's time to replace my furnace?
- Age is the first thing to check, along with how often it's calling for repairs. If a repair bill starts approaching what a new furnace would cost, or the same part keeps failing, that's a sign the furnace is done. Watch for rooms that won't hold heat or a burner that cycles more than it used to. With heat needed here from October through May, a furnace that's struggling in the fall is one you don't want to gamble on for the months ahead.
- Is a high-efficiency furnace worth it?
- It depends on how much you're heating and for how long. Homes here need heat eight months a year, so a furnace that turns more of its fuel into heat instead of losing it out the vent is working almost every month it sits in your house. Every non-weatherized gas furnace built since November 2015 has to hit at least 80 percent AFUE, and high-efficiency models go higher than that. A contractor can tell you what fits your house and your gas line, since that's part of the installation, not just the unit itself.
