Deming winters put six months of work on your furnace
From November through April your furnace is what keeps the house livable. Winter nights average 29°F through December through February, cold enough that the burner is cycling on and off most of the night to hold the temperature. Every one of those cycles asks the igniter to light the burner again, and that part wears with each try, not with the calendar.
Deming has seen six winter storms and 18 damaging wind events over the past ten years. Wind like that finds its way into a vent pipe or strains a power line, and across New Mexico 13% of households lost power for a full day or more in 2024. Most furnaces restart on their own once power returns. If yours does not, that is worth a look before the next cold night.

New Mexico requires HVAC contractors to hold a state license.
That license means New Mexico tested this contractor before letting them work on gas furnaces, and the Construction Industries Division keeps a record of who holds one. It is tied to the contractor, not to the specific job, so the same license that covers a furnace repair in Luna County covers one anywhere else in the state.
For a furnace repair, that license is what stands behind the work. Furnace repair often means checking the gas line and the connections around the burner, since a bad connection there is what makes the job dangerous, and the CID license is the state's way of saying this contractor has been checked against that risk.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat, or a safety switch has shut the furnace down. Check that the thermostat is set to heat and the temperature is above room temperature first. If that's fine, a tripped limit switch, a clogged filter restricting airflow, or a flame sensor that's dirty can all stop the furnace from firing. A furnace that won't start at all also sometimes points to a blown fuse or tripped breaker, worth checking before anything else.
- Why is my furnace blowing cold air?
- The furnace is likely running the blower without a flame lit. This happens when the igniter has failed, the flame sensor is dirty, or gas isn't reaching the burners. It can also happen right when the furnace starts a cycle, since the blower sometimes runs a few seconds before the burners ignite. If cold air keeps blowing the whole cycle, the furnace isn't heating at all and needs a contractor to find out why.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit usually means the thermocouple has worn out and is no longer sensing the flame correctly. A draft in the area around the pilot, or a dirty pilot orifice restricting gas flow, can also blow it out or starve it. Winter nights here average 29°F, so a furnace that keeps losing its pilot won't keep up on the coldest nights. This is a repair for a licensed contractor, since it involves gas components.
