No heat in a Utah winter isn't something that waits. Whether your furnace needs a part, a proper diagnosis, or a well-sized replacement, we hand you a written price at your home before anything gets taken apart — and we tell you plainly when a repair is the smarter buy.
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 thirty 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 visit starts the same way: a free, no-obligation diagnosis at your home, followed by a written price. If the honest answer is that the furnace is done, we size the replacement from a load calculation on your actual house, price two or three real options, and show you the operating-cost difference before you choose. Nothing begins until you've seen the 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.
Twenty years apart, same basementWhen replacement is the right call, everything below is part of the quoted price. No line items appear on installation day that were not on the estimate.
We measure the house rather than matching the old unit. Oversizing is the single most common installation mistake, and it costs you comfort and money for the next twenty years.
Covers: square footage · insulation · window area · duct capacity
Full removal and responsible disposal of the existing furnace, plus any adaptation the new unit needs to fit and vent correctly.
Covers: disconnect · haul-away · plenum and vent adaptation
A new furnace pushing through undersized or leaking ducts will never perform to its rating. We check before we install, and tell you if it needs work.
Covers: static pressure test · leak inspection · return air sizing
Gas line connection, venting to code, condensate handling on high-efficiency units, and thermostat wiring — all permitted and inspected.
Covers: gas · venting · condensate · thermostat
We do not just turn it on and leave. Gas pressure, temperature rise, and airflow all get set to the manufacturer's spec so the unit actually delivers its rated efficiency.
Covers: gas pressure · temp rise · airflow · safety checks
Manufacturer warranties often require registration within a set window. We file it for you, so a claim five years out does not get denied on a technicality.
Covers: registration · paperwork · labor warranty terms
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.
“Bart came out to check our AC as a second opinion after another HVAC company told us we had issues that would cost us several thousand in expensive repairs. He found the real problem and was in and out in a few minutes!”Paris S. · Google review
“Great honest service. Bart helped get our AC running again. 10/10 would recommend!”Tanner R. · Google review
“Good communication, very honest and nice. I trust Provo HVAC!”Heather P. · Google review
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.
Installed cost depends on the size and efficiency of the unit and what your venting and ductwork need. We quote the full installed price in writing after seeing the house — never a phone estimate, because a phone estimate is a guess.
That comes from a load calculation on your specific house, not from the size of your old unit. An oversized furnace short-cycles, wears out faster, and leaves rooms uneven. We size it properly.
Often yes, because our heating season is long. The honest answer depends on your gas usage and how long you plan to stay in the house — we run those numbers with you rather than assuming.
Yes — all makes and models, residential and light commercial, including older systems other companies decline. Thirty years in Utah County means we've almost certainly opened up yours before.
Everything else we do across Utah County.
Free written estimate, no diagnostic fee, and a price we will match or beat.
