No heat in a Utah winter isn't something that waits. From Lehi down to Payson, book a window online and a technician diagnoses the furnace at your home, hands you a written price, and gets your heat back on — usually the same visit.
Utah County gets cold in a hurry. Between November and February, a furnace that quits overnight turns into a genuine problem by morning — and the last thing you want is a contractor who won't tell you what the fix costs until the invoice arrives.
Provo HVAC has been repairing furnaces across Utah County for over fifty years. We've worked on thousands of heating systems in this valley, which means there is very little we haven't already diagnosed and fixed. Our technicians service every make and model, including older units that newer shops would rather replace than repair.
Every repair starts the same way: a free, no-obligation diagnosis at your home, followed by a written price. Nothing gets taken apart and no work begins until you've seen that number and said go.
Six problems we run more than any others in Utah County — and what usually causes each one. None of these need a diagnosis over the phone.
The blower runs but nothing warm comes out. Nine times out of ten the burners are lighting and then cutting out, or they never lit at all.
Usual causes: dirty flame sensor · failed igniter · gas valve · thermostat set to “on” instead of “auto”
No response at all when the thermostat calls for heat. Start with the simple things — we'll check them free before touching anything expensive.
Usual causes: tripped breaker · blown door switch · dead thermostat batteries · failed control board
It fires, runs a few minutes, shuts off, then starts again. Hard on the equipment and expensive on the gas bill — worth fixing quickly.
Usual causes: clogged filter · overheating limit switch · oversized system · blocked flue
Runs fine for a while, then quits and won't restart until it cools. That's usually a safety switch doing exactly what it was designed to do.
Usual causes: high-limit trip · restricted airflow · failing pressure switch · dirty burners
New noises are worth a call. A bang on startup is delayed ignition — that one shouldn't wait, and we'll prioritize it.
Usual causes: delayed ignition · worn blower bearings · loose ductwork · slipping belt
The one failure we won't repair around. A cracked exchanger can put carbon monoxide into the house, and we'll show you exactly what we found.
What happens next: system shut down · CO test · replacement options, no pressure
We'll tell you when a small part buys you five more winters — even when the replacement would be the bigger ticket for us.
Most people call us because the last company handed them a bill they never agreed to. Here is how a job actually runs.
Book online in about a minute, or call and talk to a person. No-heat and no-cooling calls jump the queue.
We diagnose the system at your home and hand you a written price. No obligation, no diagnostic fee, no work until you say go.
We finish the job and clean up after ourselves. If a competitor quoted lower on the same scope, bring it to us.

“I’ve used Provo HVAC twice and both times they’ve been prompt, professional, and honest. They won’t upsell you on things you don’t need.”David R. · Repeat customer
Still curious? Call — we would rather answer it now than have you guess.
It depends entirely on what failed. A dirty flame sensor and a cracked heat exchanger are the same symptom to a homeowner and two very different invoices. That's why we diagnose first and quote in writing before starting — and why the diagnosis is free.
No. The visit and the diagnosis are free, with no obligation to book the repair. You get a written price and you decide from there.
No-heat calls move to the front of the schedule in winter — same day whenever the route allows. Call rather than booking online if you're without heat right now.
A well-maintained gas furnace typically runs 15 to 20 years. Utah's cold winters push systems harder than a mild climate does, so annual maintenance matters more here than the manufacturer's brochure suggests.
Yes — all makes and models, residential and light commercial, including older systems other companies decline. Fifty-plus years in Utah County means we've almost certainly opened up yours before.
