Cortez asks a lot of a furnace, eight months a year
Your furnace works from October through May here, eight months of the year. On winter nights that average 19°F, it runs long hours to keep the house warm, and the burner cycles on and off again and again to hold the temperature. Each cycle puts wear on the igniter and the parts that control the flame.
Montezuma County has seen 115 winter storms and 22 damaging wind events over the past ten years. Wind and heavy snow put stress on the power grid, and across Colorado, 13% of households lost power for at least 24 hours in 2024. A furnace that loses power and does not restart on its own leaves a house going cold on the coldest nights, when it matters most.

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.
- Why won't my furnace turn on?
- The most common reason is the thermostat isn't calling for heat, either from dead batteries or a setting that got bumped. After that, check your breaker panel, since a tripped breaker will shut the whole system down. If power and the thermostat both check out, the furnace itself may have a failed igniter or a safety switch holding it off, and that calls for a contractor to look at it.
- Why is my furnace blowing cold air?
- Most often the blower is running before the burners have caught up, which is normal for the first minute or so after a cycle starts. If cold air keeps coming the whole time it runs, the igniter or the gas valve may not be lighting the burners at all. A dirty filter can also starve the system for airflow and throw off how it heats, so check that first since it's the easiest thing to rule out.
- Why won't my furnace pilot light stay lit?
- This usually means the thermocouple has worn out and can no longer sense that the pilot is burning, so it shuts the gas off as a safety measure. A draft blowing across the pilot or a dirty pilot orifice can cause the same problem. Either way this isn't something to keep relighting on your own since it points to a part that needs replacing.
