No heat, a furnace that lights and quits, a burner locking out on the coldest night of the year. We match Wasatch Front homeowners with a licensed contractor who can diagnose it properly — repair, replacement, or the tune-up that would have caught it back in October.
Not exciting. Just heat, working, when it's fifteen degrees outside and you need it to be.
Five kinds of work that make up most furnace calls — from a dead unit at 6 a.m. to the tune-up that would have caught it in October.
A no-heat call is usually one of a handful of failures — ignition, a safety switch, or airflow — and most of them are diagnosable within minutes of someone standing at the unit. Getting the right contractor out fast matters more here than anywhere else in the trade.

Learn more →A furnace sized off the one that's failing just carries forward whatever sizing mistake was already there. How long a furnace lasts depends on the unit, the installation and how it's used — there's no fixed number to promise, only a range that depends on those things.
Learn more →Fall is when a tune-up actually helps — before the furnace is asked to run hard on the coldest nights of the year. By January, most of what would have been maintenance has already turned into a repair call.
Learn more →A cracked heat exchanger is a combustion-safety issue, not a comfort issue, and it needs a licensed contractor's inspection, not a guess. If you suspect carbon monoxide right now, leave the house and call the gas utility or 911 before you call anyone about a service visit.

No heat, a smell, a sound, an error code, short cycling — tell us what you're seeing, not just that it's broken.
Someone licensed to work gas furnaces, matched to the job — a no-heat call at night gets treated differently than a fall tune-up.
You get told what's actually failing and why, not a part swapped on a guess. Replacement gets discussed honestly when repair no longer makes sense.
A furnace with a marginal flame sensor or a blower losing balance can limp through October, cycling on and off for fifteen minutes an hour with plenty of rest between runs. The same furnace asked to hold a house at 68 degrees when it's nine outside, or to run nearly continuously during a week-long inversion, gets no rest to hide the problem in. That's why the phone rings hardest on the first real cold snap and during the stretches of stagnant winter air that settle over the Wasatch Front — the failure was already there, the weather just exposed it.
This is also why fall is the useful time to have a furnace looked at, and why by January it's mostly triage. A tune-up in October catches the same weak flame sensor or dirty filter that would otherwise fail on the night it matters most. Once the cold has arrived, the honest answer is a repair to get you through, with any maintenance conversation held for a day when it isn't twelve degrees outside.
Furnace 801 is a referral service — we match homeowners with contractors, we do not send our own crew or open a furnace ourselves. Gas appliance work in Utah requires a licensed contractor, and for good reason: a furnace mishandled can mean carbon monoxide reaching the air in your house, not just a repair that didn't take. That is not a line worth cutting to save a phone call.
In practice that means the person who shows up is a licensed contractor equipped to diagnose the actual fault, not a generalist doing their best. And if what you're dealing with sounds less like a cold house and more like a gas or carbon monoxide problem — an alarm sounding, a specific smell, headaches that ease once you're outside — the right move is to leave the house and call the gas utility or 911, not to schedule a visit and wait.
Salt Lake, Utah, Davis and Weber counties.
Leave the house immediately and call the gas utility's emergency line or 911 — do not call us first, and do not go back inside to check anything or turn anything off. This applies whether you smell gas, a CO alarm is sounding, or you notice symptoms like headaches or dizziness that improve once you're outside. Once the situation is confirmed safe, a licensed contractor can inspect the furnace and figure out what happened.
There's no fixed number we'll give you — how long a furnace holds up depends on the specific unit, how it was installed, and how hard it's been run, and any of those can shorten or extend that considerably. The more useful question at the point of a repair is usually cost and pattern: an aging furnace with several unrelated failures in close succession is a different conversation than one with a single, isolated fault. A contractor can walk you through that for your specific unit rather than a generic age cutoff.
Because that's when it's working hardest, not because of bad luck. A furnace with a marginal flame sensor or a blower running out of balance can limp through mild weather on short, easy cycles; asked to run nearly continuously through a cold snap or an inversion, that same weak point finally gives out. The failure was usually building for weeks — the cold weather just found it.
You can, but it's not fixing anything — a lockout is the control board refusing to keep trying after failing to confirm ignition, and resetting it just buys one more attempt at whatever already failed. If it's locking out repeatedly, the underlying fault — often ignition, sensing, or a pressure switch — is still there and worth having diagnosed rather than cycled through again on the coldest night you can least afford it.
No — Furnace 801 is a referral service. We match you with a licensed contractor who does the actual gas appliance work; we don't send our own crew or perform repairs ourselves. Gas furnace work in Utah requires a licensed contractor, and that's who shows up, not a generalist or a handyman.
