Eight months of heat in Santa Fe County
From October through May, your furnace is what stands between you and a house at 20°F, the average winter low here. That is eight months of the year it has to work, not just a few cold snaps.
Most homes in Santa Fe County heat with gas, and any new non-weatherized gas furnace has to reach at least 80 percent AFUE by federal rule. Power matters too. Across New Mexico, 13% of households lost power for 24 hours or more in 2024, and the region has logged 134 winter storms and 187 damaging wind events over the past ten years. A new furnace here needs to hold up through a long season and through the outages that can come with it.

New Mexico requires HVAC contractors to hold a state license.
New Mexico licenses HVAC contractors through the Construction Industries Division. That license is issued to the contractor, not to any single job, so it covers this installation the same way it covers every other job that contractor takes on. Getting licensed means the state tested the contractor before letting them work on a system like yours.
For a furnace install, that license is what stands behind the person doing the work. Gas heat is what most homes in Santa Fe County run on, and the gas connection is the part of this job that has to be right. In most cities and counties, an install like this also needs a permit from the local building office, with an inspection once the work is done, which checks the finished job separately from the license behind the contractor.

- What size furnace does my house need?
- The right size depends on your home's square footage, how well it's insulated, your window count, and your ceiling height, not on what furnace is in there now. A furnace that's too big cycles on and off fast and never runs long enough to heat evenly. One that's too small runs constantly and still can't keep up on a 20°F night. A contractor works this out with a load calculation that looks at your actual house, not a guess based on size alone.
- How do I know it's time to replace my furnace?
- Watch for uneven heating between rooms, a furnace that runs longer than it used to, or a rising gas bill with no other explanation. Frequent repairs are another sign, especially if the same part keeps failing. Since homes here need heat from October through May, a furnace that's already struggling in the fall is a bad sign for the months ahead. If a technician has told you the heat exchanger is cracked, that's not a repair, that furnace needs to come out.
- Is a high-efficiency furnace worth it?
- It depends on how much you use your furnace and what you're replacing. With 8 months of heating season here and winter nights averaging 20°F, a furnace in Santa Fe runs a lot more than one in a milder climate, so efficiency gains add up over more hours of operation. Furnaces made since November 2015 have to hit at least 80 percent AFUE, and high-efficiency models go higher than that, meaning less gas burned for the same heat. A contractor can walk through the options for your specific house and tell you what makes sense given your ductwork and venting.
