Ten months of heat wears a furnace down here
Your furnace runs from September through June in Sweetwater County. That is ten months of the year it has to work. On winter nights that average 11°F, it is not cycling lightly, it is running long and hard to keep the house warm.
That kind of steady demand wears on the igniter and the flame sensor first, since those parts fire every time the burner lights. Most homes here heat with gas, so when a furnace won't light or won't stay lit, that is usually where the problem sits.

A new furnace would cut about $150 a year off heating for a typical Sweetwater County home.
Estimates for a typical Sweetwater County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Wyoming fuel prices and NOAA climate normals. Your home will differ.
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?
- Most often the thermostat isn't calling for heat the way you think it is, or power isn't reaching the furnace. Check that the thermostat is set to heat and the temperature is above room temperature. Check the breaker and the furnace's own power switch, which looks like a light switch near the unit. If those are fine, the igniter or a safety switch inside the furnace may be stopping it from starting, and that needs a contractor to look at.
- Why is my furnace blowing cold air?
- If air is moving but it's not warm, the furnace may be running the blower without the burners lighting. This can happen when the igniter is failing or the flame sensor isn't detecting a flame, so the system shuts the burners off as a safety measure while the fan keeps going. It can also mean the furnace is just starting a cycle, since a furnace pushes some cool air through the ducts before it warms up. If the air stays cold for more than a few minutes, that points to a problem that needs a contractor's diagnosis, especially with nights here averaging 11°F through the winter.
- Why won't my furnace pilot light stay lit?
- A pilot light that won't stay lit is usually a sign the thermocouple isn't sensing the flame correctly, so it shuts the gas off as designed. It can also mean a draft near the pilot, a dirty pilot orifice, or a failing gas valve. Since most homes here heat with gas and rely on this working through 10 months of the year, it's worth having a contractor check the thermocouple and clean the pilot assembly rather than relighting it repeatedly.
