Ten months of heat a year wears a furnace down
Evanston homes need the furnace running from September through June. That is ten months out of the year, with winter nights averaging 10°F from December through February. At that temperature the burner is cycling on and off for hours at a stretch, and every cycle puts a load on the igniter and the flame sensor.
Most furnaces here run on gas, but the blower and control board still need power to start a heat cycle. Uinta County has logged ten winter storms and fifty damaging wind events over the past ten years, and 8% of Wyoming households lost power for at least 24 hours in 2024. When the power drops, the furnace stops calling for heat even with gas still running to it.

A new furnace would cut about $150 a year off heating for a typical Uinta 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.
- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the temperature is above the room temperature, and change the batteries if it uses them. If the thermostat looks right, check your breaker panel, since a tripped breaker will shut the whole system down. Furnaces also have a flame sensor and an igniter that can fail with age, and either one will stop the burners from lighting even though the blower and controls have power. If the furnace still won't start after that, a contractor can test the igniter, the flame sensor and the control board to find which part failed.
- Why is my furnace blowing cold air?
- Most of the time this means the blower is running but the burners haven't lit yet, or they've already shut off. A dirty flame sensor is a common cause, since it can't detect the flame and shuts the gas off as a safety measure even though the fan keeps moving air. A clogged filter can also cause this, because it restricts airflow enough to trip a safety switch that cuts the burners while leaving the fan on. If you've changed the filter recently and it's still blowing cold, a contractor will need to check the flame sensor and the ignition system.
- Why won't my furnace pilot light stay lit?
- This usually points to the thermocouple, the small part that senses the pilot flame and keeps the gas valve open. When it wears out or sits out of position, it reads the flame as out and shuts the gas off, even though the pilot lit fine a moment ago. A draft near the pilot or a dirty pilot orifice can cause the same thing. Since gas is involved, this isn't one to keep relighting on your own. A contractor can test the thermocouple and replace it if that's the cause.
