Farmington is the Davis County seat, and it has been since 1852, which makes it one of the oldest established towns between Salt Lake City and Ogden. That history shows up in the houses. The Main Street historic district holds homes that are well over a century old, many of them on the National Register, sitting under mature trees on the narrow valley floor against the foot of the Wasatch. A few miles away, on the benchside slopes and out toward the west by the FrontRunner station, are subdivisions built after 2000 with larger floor plans and modern layouts. Those are two very different heating and cooling situations in one small city, and a contractor who treats them the same way gets one of them wrong.

Why Farmington Homeowners Call Us

We answer at any hour, and we do not charge more for it. A furnace that quits on a cold Farmington night gets the same flat written quote at 2 AM in January as it would on a weekday afternoon. No after hours premium.

We size equipment to the actual house

old or new. A century old home near Main Street with original construction and an added on floor plan does not have the same load as a 2010s house on the bench. We measure the home in front of us instead of guessing from square footage.

We work on all major brands

including Carrier, Trane, Rheem, and Daikin. Whatever is already in your home, we can service it or replace it.

Straight repair or replace answers.

On an older system we tell you whether a repair buys you real years or just postpones a replacement you already need. You decide with full information.

Licensed and certified.

Utah HVAC license 14184707-5501 (S350) and EPA 102123778. You are not gambling on who shows up.

We respect you, we respect your time. If we're late to a confirmed appointment, you don't pay.

Top HVAC Services We Provide in Farmington

Pricing & Offers

All of our repair and installation quotes are flat rate, written, and approved before any work starts. There is no after hours premium; the overnight rate equals the daytime rate. Financing is available on system replacements.

Service	Price	Notes
AC Repair	$228 – $3,000+	Where you fall in that range depends on the part. A capacitor swap sits near the low end; a compressor or evaporator coil refrigerant leak repair runs into the middle and upper range.
Furnace Repair	$361 – $2,575	A thermocouple or igniter replacement comes in at the low end. Heat exchanger work and blower motor assembly replacement push toward the high end.
AC Replacement	$2,500 – $8,000+	The price depends on the tonnage, SEER2 rating, brand, and whether the existing ductwork and refrigerant lines can be reused or need to be replaced. Financing is available as low as $109/month for a full system.
Furnace Replacement	$2,500 – $8,000+	The price depends on efficiency rating (80% AFUE vs 96%+ condensing), input BTU, and whether venting can be reused. The same financing applies.
Complete HVAC System	$7,000 – $25,000+	$7,000 to $25,000+. This is the range for a coordinated replacement of both pieces. For a 1995 Crooked Creek build where both the AC and furnace are original equipment, the top of this range buys variable speed, two stage, or full heat pump conversion with new line sets.
Comfort Club Plan	$177 / year	$177/year. Includes one AC tune up, one furnace tune up, priority scheduling, and 15% off all repairs. For homes with 15+ year old equipment, the two tune ups frequently catch degraded capacitors, weak contactors, and dirty coils before they turn into emergency calls in July.

FAQs About HVAC in Farmington

My house is over a hundred years old. Can you even work on the heating system?

Yes. Older Farmington homes are some of the most common calls we get, and the age is not a problem, it is information. The thing we watch for is a modern furnace bolted onto old ductwork or a home that was added onto without the system being resized. We assess the whole setup and tell you straight what it needs.

I have a newer home on the bench. Why would I need service already?

A lot of the post 2000 homes on the benchside and west side were built with builder grade equipment chosen to hit a construction price. Those units commonly start needing real repairs around ten to fifteen years in. If your home is in that range and you have not had the system looked at, a maintenance visit now is cheaper than an emergency one in January.

Is the federal heat pump tax credit still available in 2026?

No. The federal Section 25C credit for air source heat pumps expired December 31, 2025. Geothermal systems still qualify for the 30% Section 25D credit through 2032. For most Ogden homeowners the savings now come from Rocky Mountain Power Wattsmart and Dominion Energy (Enbridge Gas) ThermWise rebates rather than a federal credit.

Do you charge extra for nights or weekends?

No. We answer 24 hours a day and the quote is the same flat written number whether you call at noon on Tuesday or midnight on a holiday. Financing is available on system replacements.
