Eight months of heat puts a lot of hours on your furnace

Moab needs a working furnace from October through May. On winter nights averaging 20°F, the burner is cycling on and off for hours at a stretch to keep the house warm. Most homes here run on gas, so that means the igniter is firing again and again through the night, and each cycle is a little more wear on it. A furnace that struggled to start last winter is more likely to fail outright this winter.

Grand County has seen 92 winter storms and 55 damaging wind events over the past ten years. Wind and cold snaps put more demand on a furnace right when a power blip can shut it down entirely. Across Utah, 7 percent of households lost power for a full day or more in 2024. If your furnace has a standing pilot, it will stay lit through an outage. If it doesn't, it needs the power to come back before it will run again.

A new furnace would cut about $100 a year off heating for a typical Grand County home.

  • A new high-efficiency furnace$410 a year
  • An older furnace$510 a year

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.

Utah requires HVAC contractors to hold a state license.

The state license is tied to the contractor, not to any single job. The Division of Professional Licensing tests and records who holds it. Utah also sets a line at $7,000. Work under that amount does not require a licensed contractor.

A furnace repair can fall on either side of that line, so whether the license stands behind this job depends on what the work costs. Above $7,000, the license is what backs the repair. Below it, the state does not require one, and nothing at the state level fills that gap. A gas furnace depends on a sound connection, and that is worth getting right no matter which side of the line the job falls on. Most homes in Grand County heat with gas, which is what makes that connection the part to watch.

Why won't my furnace turn on?
Most of the time it's the thermostat, the power supply, or a safety switch stopping it before it starts. Check that the thermostat is set below room temperature and has working batteries first. If it's set right and still nothing happens, the furnace may be tripping a limit switch or not getting power at the panel. A contractor can test each part in order and find where the sequence is breaking down.
Why is my furnace blowing cold air?
The blower is running but the burners aren't lighting, so you're getting air movement without heat. This usually points to the igniter, the flame sensor, or the gas valve not doing its job. It can also mean the filter is clogged enough that the furnace is overheating and shutting the burners off early to protect itself. Either way, the fix is diagnosing which part in that chain is failing, and that needs a contractor with a meter, not a guess.
Why won't my furnace pilot light stay lit?
A pilot that won't stay lit almost always means the thermocouple has worn out and is telling the gas valve to shut off even though the flame is there. It can also mean a draft in the area is blowing the flame out, or the pilot orifice is dirty and the flame is too weak to hold. A standing pilot doesn't use electricity, so this isn't a power problem. A contractor can tell which of these it is by watching the flame and testing the thermocouple directly.
