Top 7 HVAC companies in Utah, Utah

Utah County spans roughly 636,235 residents across varied elevations. Winter design temperature sits at 10 °F while summer peaks reach 96 °F. The market shows a heating-dominant load profile with 5,000 heating degree days against 1,200 cooling degree days. Public listings supply the only data used here.

Cost data for Utah County installations

Installed costs draw from two sources. The typical full-system price is listed at $9,550, bounded by $8,600 and $10,500. A separate 2025 invoiced average reached $18,497 with the upper quartile at $27,600. Labor is stated at $110 per hour. Permit fees range from $100 to $350. The two cost sources diverge sharply, and both figures are retained because the spread itself is the usable information. Altitude derating and local code add-ons explain part of the difference between published typicals and actual invoices.

The shortlist

Companies are ranked by a Bayesian-adjusted rating: a company's star rating is pulled toward the national mean until it has enough reviews to stand on its own, so a 5.0 from four customers does not outrank a 4.9 from two hundred. Small tie-breakers apply for a public website, for being listed as an HVAC specialist rather than a general contractor, and for published 24/7 availability. This is a shortlist built from public listing data, not a review of work performed.

A-1 Heating & Cooling

A-1 Heating & Cooling operates from 6157 Spanish Oak Way, Murray, UT 84123 and lists the phone (801) 210-1018. Its 102 reviews produced a raw rating of 5.0 that adjusted to 4.986, 0.222 above the national mean of 4.764 because the large review count limited movement. The firm appears as a general contractor without 24/7 listing. These numbers say nothing about actual job quality or how the company handles change orders once work begins.

Utah's Best Home Pros

Utah's Best Home Pros at 3333 S 900 E #240, Millcreek, UT 84106 can be reached at (385) 324-1211. Forty-seven reviews at a raw 5.0 adjusted to 4.968, pulled 0.204 above the mean by moderate volume plus the 24/7 availability signal. The listing shows a general contractor category. Review count remains low enough that one or two negative entries could shift the adjusted score noticeably.

Utah's Best Home Pros

The West Valley City location of Utah's Best Home Pros sits at 2854 W 4700 S Ste C3, West Valley City, UT 84119 with the same phone (385) 324-1211. Seventy-seven reviews produced a raw 4.9 that adjusted upward to 4.922, closing 0.158 of the gap to the mean. Published 24/7 availability and a website appear in the record. The numbers give no information on how the firm performs on complex multi-zone retrofits.

HB HVAC Services Utah

HB HVAC Services Utah lists 2476 S 1300 E, Salt Lake City, UT 84106 and the phone (801) 810-7201. Its 18 reviews at a raw 5.0 adjusted to 4.893, still 0.129 above the mean because the smaller sample allowed more pull. The firm shows as a general contractor without 24/7 status. Low review depth leaves open the possibility that scores reflect a narrow customer segment.

Mountain Home Services

Mountain Home Services at 8720 Monroe St, Sandy, UT 84070 lists the phone (385) 240-3418. Seventy-four reviews at a raw 4.8 adjusted to 4.830, lifted 0.066 above the mean by volume and website presence. It appears as a general contractor. The data cannot reveal whether the firm maintains adequate parts inventory during peak winter demand.

Utah Heating and Cooling service

Utah Heating and Cooling service operates from 9198 S 300 W, Sandy, UT 84070 and lists the phone (615) 701-8152. Two reviews at a raw 5.0 adjusted to 4.799, moved 0.035 above the mean despite minimal data; 24/7 availability supplied the remaining tie-breaker. No website is shown. With only two reviews the adjusted score remains highly sensitive to any future rating change.

Harris-Dudley Co. | Radiant Heating & Snow Melt Systems Salt Lake City UT

Harris-Dudley Co. | Radiant Heating & Snow Melt Systems Salt Lake City UT is located at 3039 Specialty Cir, South Salt Lake, UT 84115 and lists the phone (801) 363-3883. Seventy-two reviews produced a raw 4.6 that adjusted upward to 4.688, closing 0.076 of the gap to the mean through volume and website presence. It appears as a general contractor without 24/7 status. The numbers supply no detail on radiant-system expertise versus standard forced-air work.

Licensing and permits

Utah issues HVAC contractor licenses at the state level through the Department of Commerce — Division of Occupational and Professional Licensing. The current classification is S350 for HVAC contractors; a B100 general building contractor may also perform HVAC work on single-family or small multi-family projects. A new H100 classification is scheduled to phase in beginning April 20, 2026, with a grandfather window ending November 30, 2027. DOPL requires general liability insurance, though current published limits remain listed as unknown. Permits for furnace or AC changeouts are issued locally by city or county building departments. Some cities, including Salt Lake City, further require a municipal business license for mechanical contractors. Homeowners must verify both the DOPL license and any local business-license requirement before signing a contract.

Climate considerations

Salt Lake City design conditions are 10 °F winter and 96 °F summer. The county falls primarily in IECC zone 5B with a dry moisture regime. Heating degree days total 5,000 against 1,200 cooling degree days, producing a heating-leaning mixed load. Natural gas remains the dominant heating fuel. Very low humidity keeps latent loads small, so evaporative cooling remains viable in many installations. Altitude derating must be applied to both combustion equipment and heat-pump capacity. Winter inversions increase the importance of proper ventilation and filtration. Equipment sizing therefore requires explicit accounting for elevation and for the limited shoulder seasons typical of the Wasatch Front.

Incentives and rebates

Utah Home Energy Rebates remain conditionally approved with launch delayed; a planned $8,000 heat-pump rebate is the largest state offering. No state tax credit exists. Utility programs through Rocky Mountain Power wattsmart and Dominion Energy Utah ThermWise currently offer $200 to $1,500. Participation in a utility contractor network is required to access those rebates. Federal 25C and 25D credits expired at the end of 2025, leaving no residential HVAC tax credit for 2026. Only the commercial 48E ITC survives under narrow conditions. Homeowners therefore need to confirm contractor network status before any heat-pump discussion proceeds.

How to choose

Verify the DOPL S350 license and any required city business license. Confirm the contractor participates in current utility rebate programs. Request explicit altitude-derating calculations for the site elevation. Ask how fresh-air intake will be handled under inversion conditions. Compare the two published cost sources against the written scope before signing.
