Step 1 of 3: Equipment

What kind of equipment?*

A furnace here runs about ten months a year, September through June. That's most of the calendar, not just a stretch of cold weeks. Routt County has also seen 202 winter storms between 2015 and 2024, and every one of them means the furnace running longer to keep the house warm. All that runtime wears on the parts that cycle each time it fires, the igniter, the blower motor, the limit switch. A furnace that rarely shuts off for long shows wear sooner than one that only kicks on now and then, and a small issue has less time to stay small before it turns into a breakdown.

Colorado gas cost $10.09 per million Btu in 2024, among the higher rates around.

A furnace running on a bad limit switch or a cracked heat exchanger wastes that gas every time it fires, so the longer the repair waits, the more it costs to ignore.

Winter storms have hit Routt County 202 times between 2015 and 2024, and damaging wind another 47 times. That's a lot of chances for hail or flying debris to hit the outdoor parts of a heating system, even on a furnace that vents through the roof or a wall. A dented vent cap or a flue pipe knocked loose won't always announce itself. The furnace can keep running while it draws air wrong or vents incorrectly. If a storm came through and the furnace has acted up since, or just hasn't been looked at, that's worth a check. Statewide, 13% of Colorado households lost power for a day or more in 2024, and a furnace that depends on electronic ignition won't fire at all until power and the system both come back.

A Furnace That Runs This Much Needs a Real Diagnosis, Not a Guess

A furnace that runs ten months a year doesn't get much rest between cycles, and that's usually where the trouble starts. Have it looked at properly so whatever's worn gets replaced, not just patched.

A Newer Furnace Is Usually Worth Repairing

A furnace installed with a newer house still has years of normal wear ahead of it, not behind it. That matters when a repair call turns into a conversation about replacing the unit instead. A cracked heat exchanger or a failed control board means something different on a furnace a few years old than on one pushing past its working life. Worth asking when the system was actually installed, since the house age only tells part of it. A furnace put in when the house was built, or swapped in more recently, is usually worth the repair.

What a Failing Furnace Sounds and Smells Like

A furnace that's starting to fail usually says so before it quits outright. A burner that won't stay lit, a blower that runs but pushes cool air, short cycling where it fires and shuts off again within a few minutes, these are the furnace telling you something's wrong before it leaves you without heat. A burning smell when it first kicks on each season is normal, dust burning off. A burning smell that lingers, or a smell like rotten eggs, is not. Rattling, banging or a screech from the blower points to a part working loose or a motor bearing going bad.

When to Call and When to Watch It

Some signs mean shut it off and get someone out now. A gas smell that doesn't clear, a yellow or flickering burner flame instead of steady blue, soot around the furnace, or a carbon monoxide alarm going off all mean stop running it and call. Other signs are worth watching but not ignoring: uneven heat room to room, a thermostat that seems to lose the argument with the weather, or a furnace that takes longer than it used to to warm the house. Those point to a part wearing down, not a part already gone, but they get worse on their own timeline, not yours.

A new furnace would cut about $140 a year off heating for a typical Routt 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.

A repair decision really comes down to two things: what broke, and what else is close behind it. A failed igniter or a bad flame sensor is a cheap, quick fix on a furnace of any age, because swapping one part doesn't depend on what the rest of the unit has been through. A cracked heat exchanger is a different question, because that part isn't sold on its own and replacing it often costs close to a new furnace anyway. Between those two extremes, age and condition start to matter. A furnace that's needed a service call every year lately is telling you something a single repair bill won't fix. One that's run trouble-free until now, with one part failing on its own, is usually worth fixing and trusting again.
