Furnace & A/C repair in Cottonwood Heights
Furnace and A/C emergencies, seven days a week — we come out and fix what we can that night.
The canyons are beautiful. They’re also hard on your heating.
Cottonwood Heights sits higher and colder than almost anywhere else in the valley. Pressed up against the mouths of Big and Little Cottonwood Canyons, the bench catches cold air draining off the mountains after dark, picks up snow the valley floor misses, and takes the brunt of the downslope canyon winds that rake Wasatch Boulevard a few times every winter. All of that lands on one piece of equipment most people never think about — until it quits on the coldest night of the year.
We built our service around those conditions. When a system has to run this hard, the difference between a long-lived furnace and a 2am no-heat call usually comes down to whether someone caught the small stuff early: a tired igniter, a hairline crack in a heat exchanger, a furnace that was oversized for the house and short-cycling itself to an early grave. Catching that is exactly what we’re good at.

What canyon living does to your furnace
Three things make a Cottonwood Heights home tougher on a heating system than a place down on the flats:
Cold-air drainage. After sunset, cold air slides down Big and Little Cottonwood and pools on the bench. Your furnace isn’t just fighting the forecast low — it’s fighting the canyon. That means more run hours, more ignition cycles, and parts that wear out sooner than the brochure promised.
Altitude. At roughly 5,000 feet, a furnace actually delivers less heat than its sea-level rating, and combustion has to be set up for thinner air. A system that was never derated or tuned for this elevation runs dirty and works overtime — one of the first things we check.
Wind. The downslope windstorms that hammer the east bench can backdraft a flue and snuff a pilot. We make sure your venting and combustion-air supply can take what the canyon throws at it.
The bench checklist
What we look hard at on a Cottonwood Heights heating system:
- Heat-exchanger cracks
- Carbon-monoxide safety
- Igniter & flame-sensor wear
- Airflow & static pressure measured
- Flue draft & combustion air
- Short-cycling & oversizing
- Filter & blower airflow
- Two-stage / variable upgrades
Hot upstairs, cold basement? Up here, it’s the #1 thing we fix.
So many Cottonwood Heights homes are the split-levels and tri-levels built in the ’70s and ’80s — great houses, with finished basements and additions added on over the decades, and a reputation for rooms that never feel the same. The bonus room over the garage roasts. The walkout basement stays freezing. The upstairs bedrooms are stuffy by morning.
That’s almost never a “buy a bigger furnace” problem. Through air balancing, sealing and insulating the ductwork running through your attic, and adding airflow to the rooms that need it, we get every level of the house to the same comfortable temperature — and trim the energy you’re wasting along the way. On one bench home we measured a vent blowing air 14°F warmer than the A/C coil, just from a single uninsulated duct run in the attic. See how even-temperature work works →

Emergency repair, cooling & air
The owner’s a licensed HVAC tech running Canyon Comfort full time — emergency repairs, temporary cooling, and airflow help across all brands, days, evenings and weekends. When a system truly needs replacing, we tell you straight and walk you through exactly why — and if you’d like, we’ll recommend an HVAC install company we trust.
Furnace & heating repair
Furnace down on a cold canyon night? We diagnose it right and fix it fast — safety-checked and tested before we leave. Days, evenings and weekends, because a cold night doesn’t wait for morning.
Air conditioning repair
Low refrigerant, failed capacitors, frozen or dirty coils, weak airflow on those full-sun west-facing lots — the real cause found and shown to you with photos.
Straight repair-or-replace advice
Bench elevation is hard on undersized or aging equipment. When a system truly needs replacing, you get the diagnosis explained plainly — why a new system is the right call — and, if you want it, a recommendation for an HVAC install company we trust. We do not sell or install new systems.
Heat pumps & dual-fuel
Heat pump or dual-fuel system down on a cold night? We diagnose it and get you warm again — and if it needs a bigger repair, we quote it in advance and finish the job ourselves.
Tune-ups & safety checks
Seasonal maintenance and combustion-safety checks that matter most this close to the canyons — we find the small stuff before a cold night does.
Mini-splits & ductless
Ductless mini-split not heating or cooling the basement, addition, or bonus room like it should? We troubleshoot the unit and its airflow and set it right.
Portable A/C rental in Cottonwood Heights
When the A/C is down or a part will not arrive until tomorrow, we bring two high-efficiency portable A/C units and a portable swamp cooler — roughly 900 square feet of cooling — set them up, and take everything down once the repair is finished. Setup and takedown is $150, plus $20 a day, and $10 a day for a third unit. Portable A/C rental pricing →
Even-temperature & duct work
Air balancing, attic-duct sealing and insulation, and airflow fixes for the split-level and tri-level homes the bench is full of. Learn more →
Indoor air quality
Air scrubbers, media filters, and steam humidifiers for the bench’s dry, dusty mountain air.
Gas lines & ductwork
Gas-leak checks, ductwork repair, and specialty diagnostics.
Why hire a repair-only HVAC contractor?
The economics of most HVAC companies point toward selling you equipment. 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 exactly why a new system is the best choice — and if you’d like, we’ll recommend an HVAC install company we trust.
The full lineup for a bench home
Dry mountain air, winter dust, and long heating seasons are hard on your home — the add-ons that clean and balance the air, matched to your house and elevation.
Smart thermostats
Better scheduling and even-temperature features, set up right for your system.
Whole-home air scrubbers
Knock down dust, dander, and odors throughout the house — a real help in the bench’s dry, dusty air.
5″ media filters
Far more dust caught than a 1″ filter, without choking airflow — changed only every 4–6 months.
Steam humidifiers
Less dry skin, static, and cracked woodwork through a long, dry mountain winter.
HRV fresh-air systems
Fresh air without throwing away your heating or cooling — great for tight, modern bench homes.
Surge protectors
Cheap insurance for the expensive control boards and compressors in a modern system.
Furnace & coil cleaning
We clean the blower and indoor coil — where airflow is actually lost — not just your ducts. Why it matters →
What it costs
Weekdays 7am–6pm, credited toward any repair you approve. Weeknights until 10pm and all weekend add $40. Airflow diagnostic, $80.
$180 for a furnace and A/C together, $90 each additional system in the same visit — with a written System Health Report and a one-year diagnostic warranty on every tune-up.
The $150 covers delivery, setup and pickup. Two portable A/C units and a swamp cooler included; a third unit is $10 a day.
A simple seasonal rhythm keeps you out of trouble
Early fall is the most important time of year up here. Cold arrives on the bench before it reaches the valley floor, so a furnace tune-up in September or October catches a weak igniter, a tired flame sensor, or an early heat-exchanger problem before the first hard freeze turns it into a midnight no-heat call. We clean the burners, check combustion and gas pressures, and make sure your venting can handle the canyon wind.
Spring is for cooling. Many Cottonwood Heights lots face west and take the full afternoon sun, so we get your A/C or heat pump tuned — coil cleaned, refrigerant checked, airflow verified — before the first heat wave, when everyone calls at once.
Any time you notice short-cycling, rising bills, uneven rooms, or anything that smells or sounds off, call early. Small problems are cheap; the breakdown they turn into is not. And because a lot of larger bench homes run two or three separate systems, we’ll service them all in one visit — each one after the first at a discount.
Neighborhoods we know well
From the older streets around Old Mill and Canyon Cove to the homes lining Wasatch Boulevard and the “Top of the World” bench above it, the housing here is mostly established — a lot of it 30 to 50 years old, with the original ductwork and, in plenty of cases, a furnace that’s living on borrowed time. Closer to Fort Union Boulevard and Bengal Boulevard you’ll find newer construction mixed in, and right at the canyon mouths the exposure to wind and cold is at its most extreme.
We work on all of it — the 1970s split-level that needs repair-or-replace advice, the remodeled home that added a wing the furnace can’t keep up with, and the newer high-efficiency build that just needs steady maintenance. Wherever you are in Cottonwood Heights, you’re a quick drive from us, and we leave it cleaner than we found it while we’re in it.

Do you install or replace air conditioners and furnaces in Cottonwood Heights?
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 an HVAC install company we trust. No replacement sale influences the advice.
My A/C isn’t cooling or it’s blowing warm air — can you fix it in Cottonwood Heights?
Yes. Canyon Comfort repairs A/C systems in Cottonwood Heights 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 Cottonwood Heights?
Yes. Canyon Comfort provides emergency A/C repair in Cottonwood Heights during the day, evenings until 10pm, and weekends.

Do you charge extra for a night or weekend visit in Cottonwood Heights?
Yes. HVAC diagnostics in Cottonwood Heights 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 Cottonwood Heights?
Yes. Canyon Comfort diagnoses and repairs all major A/C, furnace, and heat pump brands in Cottonwood Heights, 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 Cottonwood Heights?
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 Cottonwood Heights 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 Cottonwood Heights home is uneven floor to floor — can you figure out why?
Yes. Canyon Comfort diagnoses airflow and comfort problems in remodeled Cottonwood Heights 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 Cottonwood Heights?
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.
How much does it cost to rent a portable A/C in Cottonwood Heights?
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 units that cover roughly 900 square feet together, plus a portable swamp cooler, and we pick everything up once your repair is finished. See temporary cooling →
How fast can you get to Cottonwood Heights?
Usually the same day you call, inside our service windows: weeknights until 10pm, Saturday 8am–10pm, and Sunday 8am–9pm. Cottonwood Heights sits in the middle of our service area, roughly 15 miles south of downtown Salt Lake City. If your heat or your cooling is out, call or text 801-960-5925.
Does my furnace really need to be sized for the altitude?
Yes. At roughly 5,000 feet, a furnace produces noticeably less heat than its sea-level rating, and the burners should be set up for thinner air. A system that was oversized to “make up for it” ends up short-cycling and wearing out early. We tune and service for the home and the elevation — it’s one of the first things we check up here.
Why is my upstairs hot and my basement freezing?
It’s the most common complaint we hear in Cottonwood Heights’ split-level and tri-level homes, and it’s usually about airflow and duct losses — not furnace size. Air balancing, sealing and insulating attic ducts, and adding airflow to the rooms that need it can even out the whole house. More on even-temperature work →
The canyon wind keeps knocking out my furnace — what’s going on?
Strong downslope winds on the east bench can backdraft a flue or disrupt combustion, especially on older or improperly vented systems. We check your venting, draft, and combustion-air supply so a windstorm doesn’t leave you without heat.
How often should I service my furnace and A/C in Cottonwood Heights?
Once a year each is the sweet spot — furnace in the fall, A/C in the spring. Because bench systems run more hours against colder nights and hotter west-facing afternoons, annual maintenance pays for itself in fewer breakdowns, lower bills, and a longer equipment life. If you run more than one system, we’ll service them all in the same visit at a discount.
Can I book my furnace and A/C tune-ups together in Cottonwood Heights?
Yes — a furnace and A/C tuned in the same visit is $180, against $110 for a single system, and each additional system after that is $90. That math helps on the bench, where larger homes often run two or three separate systems. Each one ends with a written System Health Report of actual readings, so you see how every system is actually doing, not just that someone looked at it.
My energy bills are climbing — is my system the problem?
Often, yes. A dirty blower wheel or indoor coil, a refrigerant problem, leaky or uninsulated ducts, or a furnace that short-cycles will all quietly drive your bills up while making the house less comfortable. We’ll measure what’s actually happening and show you the numbers — sometimes it’s a simple cleaning, sometimes it’s worth weighing a high-efficiency upgrade.
Is a heat pump a good choice in Cottonwood Heights?
It can be a great option, especially paired with gas backup for the coldest snaps. Modern cold-climate heat pumps handle our winters well and are very efficient in the shoulder seasons. We repair heat pumps of every brand, and if you’re shopping for one we’ll give any quote you’ve got a free online second opinion.
