Furnace & A/C repair in Millcreek
Furnace or A/C down? We’re available seven days a week to get you back up and running, often the same day.
A town of established homes — and a few quirks
Millcreek only became its own city in 2016, but the neighborhoods go back generations. Below Mount Olympus and along the foothills you’ll find mid-century ramblers and split-levels, many with finished basements, additions, and bonus rooms tacked on over the years. Down toward the valley floor and the new town center, there’s a growing mix of townhomes and updated homes.
What ties it together for us is the equipment: a lot of original-footprint heating and cooling systems quietly working overtime to cover rooms they were never sized for. That’s why the single most common call we get in Millcreek isn’t “no heat” — it’s “why is this room always wrong?” It’s the work we do most often here, and it shows.

Why hire a repair-only HVAC contractor?
Ask yourself who profits if your system is declared dead — at most companies, the diagnoser does. Canyon Comfort doesn’t sell or install equipment at all, so there is no replacement quota behind our advice. When a $220 repair fixes it, that’s the whole answer: you see the actual readings and photos of what we found. And on the day a system truly is finished, we tell you straight and walk you through why a new system is the best choice — and if you’d like, we’ll recommend a trusted local installation company.
What actually makes us different
Four things that protect your comfort and your wallet on every visit.
Foothill ramblers near Mount Olympus, sized right
Finished basements, additions, and bonus rooms tacked onto Millcreek’s mid-century ramblers over the years often outgrew the original ductwork. We size the fix to what your home actually is now — not what it was in 1962.
Every tune-up ends with a System Health Report
You keep the actual readings: static pressure, airflow, temperatures, and electrical on every furnace and A/C tune-up, plus a CO safety test on every furnace. See what’s in it →
Photo proof on every single job
The dirty coil, the cracked heat exchanger, the finished repair — documented before and after. You see the real condition, not just our word. See our real job photos →
Two or three systems? Save on every one
Bigger Millcreek homes often run multiple furnace-and-A/C systems. We service them all in one scheduled visit — $180 for a furnace + A/C pair, $110 for a single system, and just $90 for each additional system after that. Book your tune-ups →

No heat or no cool in Millcreek?
Book online in under a minute, or call or text us directly. We cover Millcreek and the whole Wasatch Front weeknights until 10pm and all weekend, and same-evening help is usually available.
Hot upstairs, cold basement? This is our specialty.
The bonus room over the garage that bakes. The finished basement that stays freezing. The back addition the furnace can’t quite reach. In Millcreek’s split-levels and added-onto ramblers, it’s incredibly common — and it’s almost never a reason to rip out a working system.
Through air balancing, sealing and insulating the ductwork running through your attic, adding returns and airflow to the rooms that need it, and a mini-split where the layout calls for one, we get every level of the house to the same comfortable temperature — and cut the energy you’re wasting in the process. On one Wasatch Front home we measured a vent blowing air 14°F warmer than the A/C coil, just from a single uninsulated attic duct. See how even-temperature work works →

Common Millcreek problems — and when to call
The calls we get most in Millcreek follow the housing: a furnace that short-cycles, blows cold air, or won’t hold heat on a cold foothill night, an ignitor or flame sensor that gives out at the worst possible hour, weak airflow from a dirty blower wheel or clogged indoor coil, an A/C low on refrigerant or down to a failed capacitor, and — more than anything — that one room that’s never the right temperature. We diagnose the actual cause, show it to you with photos, and fix it rather than guessing or throwing parts at it.
Because so many systems here are original to homes built decades ago, “is it worth fixing?” comes up a lot. We’ll give you the math both ways — the cost of the repair versus what a properly sized replacement would actually save — so you can decide with real numbers. Plenty of older Millcreek systems have another good repair left in them, and we’ll tell you when that’s the smart move.
Timing matters too. With the foothills right there, cold arrives early, so a furnace tune-up in early fall catches a weak igniter or a tired part before the first hard freeze finds it. A spring tune-up gets your A/C ahead of the summer heat. The cheapest repair is almost always the one we catch on a maintenance visit — long before it becomes a no-heat call at 10pm in January.

What a “quick fix” really takes
A lot of what looks like a five-minute repair isn’t. Done right, repairing a leak, changing a TXV, or replacing a component means recovering the old refrigerant properly, pulling a deep vacuum to get every trace of moisture out of the system, brazing clean joints, weighing in the exact charge, and testing the result. Skip those steps and the “fix” comes right back, often worse.
That matters even more on Millcreek’s older equipment, where a sloppy repair can finish off a system that had years left in it. We carry the full kit to every job and use it, because doing it correctly the first time is cheaper for you than doing it twice. And because so many systems here are at the “is it even worth fixing?” stage, we’ll always give you the repair-or-replace math.
We treat your Millcreek home like it’s our own
Your home isn’t a job site to us. We lay down drop cloths, set our tools and equipment on protective mats, keep the work area organized, and clean up completely before we leave.
It’s a small thing that says a lot — and in Millcreek’s well-kept, established homes it matters. Customers tell us again and again that we “left no trace” any work was done. You shouldn’t have to clean up after the people you hired, and with us you won’t.

Getting more out of an older Millcreek home
You don’t always need a new system to cut your bills and even out your comfort — and in a mid-century Millcreek home, the cheap wins usually come first. The single most overlooked one is airflow. A clogged filter, a dirty blower wheel, or a grimy indoor coil makes your furnace and A/C work far harder than they should, and most homeowners never see it happen. Keeping a quality, airflow-friendly filter in place (we like a MERV 8, not a high-MERV filter that chokes the system) and having the blower and coil cleaned on a regular tune-up often restores comfort that crept away so slowly nobody noticed it leaving.
The next win is the ductwork. Homes here have been added onto and remodeled for decades, and the ducts that run through unconditioned attics and crawlspaces are frequently leaky and uninsulated — pouring the air you paid to heat and cool into spaces you’ll never live in. Sealing and insulating those runs, balancing the dampers, and adding a return where a room is starved are some of the highest-return improvements we make, and they’re a fraction of the cost of a new system. See how even-temperature work works →
Small habits help too: a smart thermostat that actually follows your schedule, keeping supply registers and the outdoor unit clear, and changing filters on time. And when a system genuinely is near the end — which plenty of original Millcreek equipment is — that’s when a right-sized, high-efficiency replacement starts to pay for itself in lower bills and steadier temperatures. We’ll tell you straight where your home sits on that curve, and which improvements are worth doing now versus later.
Neighborhoods we know well
From the foothill streets up near Mount Olympus and the homes along Millcreek Canyon Road, to the established neighborhoods around Olympus Cove and the busier corridors near 3300 South and Highland Drive, the housing here leans established — lots of 1950s–70s ramblers and split-levels, with newer townhomes filling in around the growing town center. Closer to the canyon, colder nights make dependable heat matter more; everywhere, decades of remodels make even airflow the difference between a comfortable house and a frustrating one.
We’re a quick drive to all of it, and we treat every Millcreek home — the original-owner rambler and the just-renovated bungalow alike — like it’s our own.

Licensed, insured, and 5.0-rated on Google, serving Millcreek days, evenings and weekends. Call or text 801-960-5925.
Do you install or replace air conditioners and furnaces in Millcreek?
No. Canyon Comfort is a repair-only HVAC company, so we repair existing furnaces and air conditioners but do not sell or install new systems. If testing shows that replacement truly is the right choice, we tell you the diagnosis and walk you through why a new system is the best option — and if you’d like, we’ll recommend a trusted local installation company. No replacement sale influences the advice.
My A/C isn’t cooling or it’s blowing warm air — can you fix it in Millcreek?
Yes. Canyon Comfort repairs A/C systems in Millcreek that run without cooling, blow warm air, freeze up, or trip the breaker, often the same day. We diagnose the actual cause — such as low refrigerant, a failed capacitor, a dirty or frozen coil, or compressor trouble. If a repair has to wait, portable A/C rental is available to keep the home comfortable.
My system is blowing out cool air, but my home isn’t cooling. What’s wrong?
First, check whether the outdoor A/C unit is actually running. Sometimes the air coming from the vents is just cooler basement air being circulated, or it feels cool simply because it’s moving — even though the A/C itself isn’t cooling. If the thermostat is calling for cooling but the outdoor unit isn’t running, or the system keeps running without bringing the temperature down, call Canyon Comfort at 801-960-5925 for A/C repair.
Do you offer emergency or after-hours A/C repair in Millcreek?
Yes. Canyon Comfort provides emergency A/C repair in Millcreek during the day, evenings until 10pm, and weekends.

Do you charge extra for a night or weekend visit in Millcreek?
Yes. HVAC diagnostics in Millcreek are $80 weekdays from 7am–6pm and $120 weeknights and weekends, which is the regular $80 diagnostic plus a $40 after-hours charge. If you approve the repair, the $80 diagnostic is credited toward it.
Do you service all A/C, furnace, and heat pump brands in Millcreek?
Yes. Canyon Comfort diagnoses and repairs all major A/C, furnace, and heat pump brands in Millcreek, including Lennox, Goodman, Amana, Carrier, Rheem, and Trane. We work on both older systems and current high-efficiency equipment.
Do you work on older furnaces and A/C systems in Millcreek?
Yes — older furnaces and A/C systems are a specialty. We’re a repair-only HVAC company, so we have no reason to call a system too old: we repair older equipment other companies write off, check parts availability before the visit, and walk you through the same repair-or-replace math either way. Age alone never means replacement.
Will you protect my floors and keep the work area clean?
Yes. We put down protective coverings where needed, keep the work area organized, and clean up completely when the job is finished. Your furnace room or hallway closet gets the same care as the finished areas of your home.
Do you work on larger homes with multiple systems?
Yes. Canyon Comfort services Millcreek homes with two, three, or more furnace and A/C systems in the same visit. For tune-ups, the first system is $110 and each additional system completed during the same visit is $90; a furnace and A/C combination is $180.
What do you actually check in a furnace tune-up?
A Canyon Comfort furnace tune-up measures airflow, static pressure, temperature performance, and electrical operation and includes a carbon monoxide safety test. The readings are documented in a written System Health Report so you know how the system is actually performing. Tune-ups are $110 for the first system, $90 for each additional system in the same visit, or $180 for a furnace and A/C together, and include a one-year diagnostic warranty that waives the diagnostic fee if the tuned system breaks down within a year.
What happens if my furnace or A/C breaks down after a tune-up?
If a system we tuned up breaks down within a year of the visit, the diagnostic fee is waived — that’s our one-year diagnostic warranty, included with every tune-up. We come out, find the problem, and quote the repair up front, with no diagnostic charge standing between you and the answer.
My remodeled Millcreek home is uneven floor to floor — can you figure out why?
Yes. Canyon Comfort diagnoses airflow and comfort problems in remodeled Millcreek homes, where additions and layout changes can leave rooms underserved or ductwork mismatched. We measure airflow and static pressure to identify where the problem is before recommending corrections such as air balancing, duct sealing, return-air improvements, or other airflow changes.
Can you diagnose rooms that are always too hot or too cold in Millcreek?
Yes — uneven rooms are an airflow problem we diagnose with instruments, not guesses. The $80 Airflow Diagnostic measures total airflow and static pressure to find where air is being lost or restricted, and you get a written plan for fixing it — air balancing, duct sealing, added returns, or zoning where the layout calls for it.
Is it worth upgrading to a high-efficiency system?
Sometimes. Whether a high-efficiency system makes sense depends on the home, existing equipment, comfort problems, energy use, and the cost of the upgrade. Canyon Comfort does not sell or install new systems, so we can explain the options without having a replacement system to sell you.
Do you offer after-hours emergency A/C repair in Millcreek?
We do. Canyon Comfort covers Millcreek days, evenings and weekends — Monday–Friday 7am–10pm, Saturday 8am–10pm, and Sunday 8am–9pm. Whether it’s no heat on a cold night or no cooling in a heat wave, we’ll get to you. Call or text 801-960-5925.
Is an evening or Saturday call billed at an after-hours rate in Millcreek?
Yes, a little. A 9pm weeknight or a weekend visit is $120 - the $80 service call plus $40 - and the $80 is credited toward the repair.
Why is one room in my house always hot or cold?
It’s the most common thing we’re called for in Millcreek, and it’s usually airflow and duct losses — not furnace size. Air balancing, sealing and insulating attic ducts, adding returns, and sometimes a mini-split can even out the whole house without replacing your system. More on even-temperature work →
My addition is freezing — do I need a whole new furnace?
Almost never. Additions are often left off the original ductwork or under-served by it. A ductless mini-split or a duct/airflow fix usually solves it for far less than a new system — we’ll tell you straight which makes sense.
How fast can you get to Millcreek?
Most Millcreek calls are handled the same day, in the next evening or weekend window. We run weeknights until 10pm, Saturday 8am to 10pm, and all day Sunday, and Millcreek is a short drive from most of our route. Call or text 801-960-5925 and we’ll book you into the next opening.
My home is older — should I repair or replace the system?
We’ll give you the math both ways — the cost of the repair versus what a right-sized replacement would save. Plenty of older Millcreek systems are worth one more good repair, and we’ll say so when they are. When it’s genuinely replacement time, we diagnose it fully rather than selling you one ourselves.
How often should I have my furnace and A/C serviced?
Once a year each is the sweet spot — the furnace in early fall before the foothill cold arrives, the A/C in spring before summer. Annual maintenance is the cheapest insurance there is: it catches small problems while they’re still small, keeps efficiency up, and adds years to equipment that’s already working hard. If you run more than one system, we’ll service them all in the same visit, discounted after the first.
How much does a furnace tune-up cost in Millcreek?
A furnace or A/C tune-up is $110 per system, a furnace + A/C combo is $180, and each additional system in the same visit is $90. Every tune-up ends with a written System Health Report of actual readings; the tune-up checklist shows exactly what we measure. Book a tune-up and the $80 airflow diagnostic is half price on the same visit.
What size furnace or A/C does my Millcreek home need?
Rarely the biggest one, and rarely whatever happened to be there before. Correct sizing comes from the square footage, windows, insulation and layout of your specific home. We do not sell or install new systems — if you’re shopping for a replacement, send us the quote and we’ll review the sizing online at no cost. Oversized equipment short-cycles, wears out early and leaves rooms uneven; a right-sized system runs longer, quieter cycles that keep the whole house comfortable.
My furnace is blowing cold air — can you fix it tonight?
Yes, no-heat calls are exactly what our evening and weekend windows exist for. A furnace blowing cold air is usually an ignitor, a flame sensor, a pressure switch, a tripped limit or a lockout from short cycling, and most of those we repair on the spot. The visit is $80 weekdays 7am to 6pm (weeknights until 10pm and the whole weekend add $40), and the $80 is credited toward the repair. No repair is too big — bigger jobs get one clear quote, fast scheduling, and the same careful work, finished by us.
How much does a portable A/C rental cost in Millcreek?
A portable A/C rental is $150 for delivery, setup and takedown, plus $20 a day, and $10 a day for a third unit. You get two high-efficiency portable A/C units covering about 900 square feet together, plus a portable swamp cooler. We can usually have them running the same day, which is what keeps a Millcreek house livable while a part is on order.
Do you work on swamp (evaporative) coolers?
Yes — we repair and maintain swamp coolers. We don’t replace or install new ones, and we don’t handle removals or conversions. We also cover furnace, A/C, and heat pump repair.
Can you help lower my energy bills?
Often, yes — and frequently without a new system. Clean airflow, sealed and insulated ducts, the right filter, a smart thermostat, and regular maintenance all add up. We’ll measure what your system is actually doing and point you to the improvements with the best payback for your specific home, whether that’s a $0 habit change or a high-efficiency upgrade.
