Eleven months of heat, and nights near 10 degrees

Woodland Park only gets a break from the furnace for about a month. The other eleven, it is running, and on a winter night when the temperature outside sits around 10°F, it runs hard to keep the house warm. That means more cycles, more start-ups, more chances for a worn part to fail right when you need it most.

The igniter takes that wear first. It lights the burner every single cycle, and after enough winters at this cold, it can crack or stop glowing hot enough to catch the gas. When that happens, the furnace tries to start and shuts itself off instead, and the house goes cold on a night that is nowhere near warm enough to wait until morning.

A new furnace would cut about $140 a year off heating for a typical Teller County home.

  • A new high-efficiency furnace$570 a year
  • An older furnace$710 a year

Estimates for a typical Teller County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Colorado 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. Make sure it's set to heat and the temperature is above room temperature, and check that it has power if it runs on batteries. If the thermostat looks fine, check the furnace switch, which looks like a light switch near the unit, and make sure it's on. A tripped breaker or a furnace filter clogged enough to shut off airflow can also keep it from starting. If none of that works, the igniter or the flame sensor may have failed, and that calls for a contractor to check.
Why is my furnace blowing cold air?
Most of the time this means the blower is running but the burners haven't lit. Check your thermostat fan setting. If it's set to "on" instead of "auto", the blower runs constantly and pushes cold air between heating cycles, which feels like the furnace isn't heating at all. If the fan is set to auto and you're still getting cold air, the igniter, flame sensor, or gas supply may be the problem, and a contractor will need to look at it. With winter nights here averaging 10°F, even a short stretch of cold air from the vents is worth checking right away.
Why won't my furnace pilot light stay lit?
This usually points to the thermocouple, a small sensor that shuts off gas flow if it doesn't sense the pilot flame. If it's worn out or positioned wrong, it can cut the gas even when the pilot is burning fine. A draft blowing across the pilot, or a dirty pilot orifice, can also blow it out repeatedly. A thermocouple is a straightforward part for a contractor to replace, but the pilot assembly itself shouldn't be adjusted without knowing gas systems well.
