Watch: why families plan their replacement now
See my replacement priceDoes any of this sound like your house?
- The furnace is older than your car.Past fifteen years, every winter is a gamble.
- The gas bill climbs every year while the house never feels warmer.Old furnaces burn more to give you less.
- One room is an icebox and another is an oven.Nobody wants the bedroom over the garage.
- You paid for a repair last winter, and the one before that.And you're wondering what breaks next.
- In July the AC runs all afternoon and upstairs still sits at 80.Utah summers keep getting hotter.
- It's making sounds it never used to make.Banging, rattling, a hum that wasn't there last year.
- Dry air, dust on everything, and somebody's always sick.Your system moves every breath in the house.
- You lie awake wondering if that old furnace is safe.A cracked heat exchanger can leak carbon monoxide.
If you nodded at two or more, it's worth a free look. Steve will tell you straight whether to fix it or replace it. See your price

“How nice it is to have a great person like you to help our family with all of our repairs. The men you have working for you are the best!”

Why Cozi Air? Because you don't have to choose.
When you replace a furnace or AC, almost every option out there asks you to give something up to get something else. Cozi Air is the one choice where you get all of it at once.
The usual trade-offs
A big company
A big operation and a big ad budget. But you usually never meet the owner, and the person who sells you the system may not be the one who puts it in.
A one-truck guy
You get the owner, and that's worth a lot. Then check the license, the insurance, and what happens when the new system doesn't fit the old ductwork.
The lowest bid
It looks best on day one. Ask what got left out to get there, because you'll live with that system for fifteen or twenty winters.

When one choice gives you the owner, the backing and eighty-plus years of the same family name, the comparing gets easy.
Still comparing? Ask every company these seven questions.
- Who answers when I call?
- A real person at a family shop in Spanish Fork. You get Madison or Steve himself, never a call center.
- Who will actually be in my house?
- Steve and his own crew. Steve looks at your home before you ever get a price, and he stands behind every install with his family name.
- Are you licensed and insured, and can I check?
- Yes. Utah contractor license 10391378-5501 (HVAC, H100). $1 million general liability per claim, a $1 million umbrella and workers' comp for every person on the job. Look us up on the state's license search.
- Will you push one brand on me?
- We're a Bryant and Carrier dealer and we can get any major brand, so the system we recommend is the one that fits your house and your budget.
- What if the new system doesn't line up with my old ductwork?
- We build the fitting in our own sheet metal shop, the one the family opened in 1938, so a tight closet or an odd plenum is no problem.
- What happens if something's wrong after the install?
- We come back and make it right. Every job is guaranteed for a full year, on top of every manufacturer warranty.
- Will you still be around in ten years?
- Same family, same building, since 1938. Five generations of Smiths have answered for their work from that shop, and Steve answers for yours.

Good questions.
How do I know it's time to replace instead of repair?
Age, repair history and how much it costs you to run. If your furnace is past fifteen years and the repair is a big one, replacing usually makes more sense. If a repair is the smarter move, Steve will tell you that too.
Will you try to sell me something I don't need?
No. You'll see good, better and best side by side with real prices, and you pick. Plenty of homes are happy with the good option.
Do you offer financing?
Yes. Low monthly payments are available on new systems. Ask when you book and Steve will walk you through it.
Should I replace the furnace and AC together?
Often it's worth it, because they're built to work as a matched pair and you only pay for one install. If one of them still has years left, we'll tell you.
Where do you work?
All of Utah County from our shop in Spanish Fork, plus south Salt Lake County and down to Nephi.
