Eight months of heat puts real wear on your furnace
In San Miguel County you need your furnace from October through May. That is eight months of the year, with winter nights averaging 22°F from December through February. A furnace working that many cold nights cycles on and off over and over, and every start puts wear on the igniter and the parts that get it burning.
This area has also logged 107 winter storms and 222 damaging wind events over the past ten years, and 13% of New Mexico households lost power for at least 24 hours in 2024. A furnace that loses power and does not come back on when it returns is worth checking, especially on a cold night when you need it most.

A new furnace would cut about $60 a year off heating for a typical San Miguel County home.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
New Mexico requires HVAC contractors to hold a state license.
The Construction Industries Division tests contractors before it licenses them and keeps a record of who holds that license. It is issued to the contractor, not to a single job, so the same license covers this repair and any other HVAC work that contractor takes on.
For a furnace repair, that license is what stands behind the person working on your gas connection. A bad connection is the dangerous part of this job, and in New Mexico it is the state license, tied to a contractor who was tested and is on record, that answers for it. About 31.1% of homes in San Miguel County heat with gas, so this is not rare work here.

- Why won't my furnace turn on?
- The most common cause is the thermostat not calling for heat, whether that's dead batteries, a tripped breaker, or a setting that's off. Check the thermostat first, then the breaker box. If both look fine, the igniter or the flame sensor may have failed, and a furnace can't run without either one working.
- Why is my furnace blowing cold air?
- Usually the blower is running before the burners have lit, or the burners haven't lit at all. Give it a few minutes after startup, since some cold air at the beginning is normal. If it keeps blowing cold with no warm-up, the igniter or the gas valve likely isn't doing its job, and with homes here needing heat from October through May, that's worth getting looked at soon.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit almost always points to the thermocouple. That's the small sensor that tells the gas valve the flame is burning, and once it wears out or sits out of position, the valve shuts the gas off as a safety measure. A draft blowing across the pilot can also do it. Either way, this isn't something to keep relighting on your own, since it means the safety system isn't working the way it should.
