Overview
What fails on a Utah furnace — and what it costs
Most furnace repair calls in Utah come down to the same half-dozen failures — flame sensor, ignitor, blower motor, pressure switch, gas valve, or control board. Our techs carry all of them on the truck in common sizes, which is why 70%+ of repair calls finish the same visit.
Utah winters punish furnaces differently than the rest of the country. Single-digit nights run compressors and gas burners at max output for weeks. Cold inversion days trap combustion byproducts. Sooty flame sensors, cracked heat exchangers from thermal cycling, and stuck pressure switches are the failures we see most.
The six most common calls
- Flame sensor cleaning or replacement — $145–$245, usually 30 minutes
- Hot surface ignitor replacement — $245–$395
- Pressure switch — $285–$485
- Gas valve — $385–$685
- Blower motor — $485–$925 (ECM pricier than PSC)
- Control board — $385–$825
What Valley does differently
Every truck carries the common repair parts. When we diagnose, we show you the part that failed and explain what it does. If you're hovering near end-of-life (usually 15-20 years on a gas furnace), we'll give you the honest repair-vs-replace math before you sink $800 into a unit with 2 winters left.
Winter emergencies get priority. Below 20°F overnight, a failed furnace means frozen pipes in a few hours, which turns a heating repair into a plumbing catastrophe. Quality Service Club HVAC members skip the regular dispatch queue on hard-freeze nights.

Warning signs
Signs Your Furnace Needs Attention
Most furnace failures announce themselves before the full breakdown. If you're hearing or seeing any of these, get it looked at before it dies in January.
Furnace blows cold air or lukewarm instead of hot
Short cycling — runs 2-5 minutes then shuts off, repeats
Thermostat is calling for heat but furnace isn't responding
Pilot light (older units) keeps going out
Clicking or rumbling from the burner area
Strange smells — electrical burning, gas, or musty
Yellow flame color instead of blue (carbon monoxide risk)
Higher gas bills with no change in thermostat setting
House has uneven heating — some rooms cold, others fine
Below zero
No heat on a 10° Utah night? Don't wait.
Below 20°F overnight, a dead furnace turns into frozen pipes in 4–6 hours. Call right away — 60-90 minute emergency dispatch, 24/7 all winter.

The Process
How a Furnace Repair Call Goes
On the truck
Cable machine, jetter, and pipe camera — every call.
Phone triage
We ask the symptom, model if you have it, age of the unit. Half the time the diagnosis is 80% locked before we dispatch.
Full-system diagnostic
Tech tests ignition sequence, gas pressure, flame rectification, pressure switch, blower amperage, heat exchanger visual, and thermostat call. Walk-through before any quoting.
Honest quote
Flat-rate for the repair, given upfront. If your system is 17 years old and the quote is $900, we'll do the math on replacement before you authorize.
Same-visit fix when possible
Most common parts are on the truck. Control boards for less-common brands occasionally need to be ordered (next day).
Safety check before we leave
CO test at every register, flame color check, combustion analysis on newer units. Not optional — we don't leave with an unsafe unit running.
