Your furnace runs every month of the year here

In Cody, there's no season when the furnace gets a rest. Winter nights average 12°F from December through February, cold enough that the burner is cycling on and off most of the night to keep up. Every one of those cycles puts a load on the igniter and the parts that get the burner lit. That's usually where trouble shows up first, as a furnace that won't start or that starts and then shuts back down.

Most homes here heat with gas, and gas furnaces need power to run the blower and controls even though the flame itself doesn't. Park County sees its share of winter storms, and when the power drops mid-cold snap, some furnaces come back on their own and some don't. If yours stays quiet after the lights come back, that's worth a call.

A new furnace would cut about $170 a year off heating for a typical Park County home.

  • A new high-efficiency furnace$680 a year
  • An older furnace$850 a year

Estimates for a typical Park 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?
Start with the thermostat. Check that it's set to heat and the temperature is above room temperature, and check the batteries if it uses them. If the thermostat looks fine, check the breaker for the furnace and the switch that looks like a light switch near the unit, since that shuts the furnace off during service and gets bumped off by accident. Gas furnaces also need the pilot lit or the igniter working, so if you smell gas at all, leave the house and call the gas company before doing anything else. With nights averaging 12°F here in the winter, a furnace that won't start needs a contractor out fast.
Why is my furnace blowing cold air?
Most often the blower is running before the burners have caught up, which is normal for a minute or two after startup. If cold air keeps coming for longer than that, the igniter or flame sensor may be failing, so the burners aren't lighting even though the blower runs. A dirty filter can also make this worse by starving the burners of the airflow they need. Check the filter first, since that's the one thing you can rule out yourself, and if the air stays cold call a contractor before the house loses too much heat.
Why won't my furnace pilot light stay lit?
A pilot that won't stay lit is usually the thermocouple, the small sensor that tells the gas valve the flame is burning. When it wears out or sits slightly out of position, it reads no flame even when there is one, and the valve shuts the gas off. Drafts near the furnace can also blow the pilot out, so check for anything blocking a vent or door nearby. This isn't something to keep relighting on your own since it points to a part that needs replacing, and with homes here needing heat all year a furnace that keeps going out is worth getting looked at soon.
