Top 7 HVAC companies in Davis, Utah

Local Climate and Equipment Demands

Davis County sits in IECC zone 5B with a dry moisture regime. Heating degree days reach 5000 while cooling degree days total only 1200, creating a heating-leaning mixed load profile. Salt Lake City winter design temperature is 10 degrees and summer design reaches 96 degrees with very low humidity. Natural gas remains the primary heating fuel. Heat pumps are suitable with backup. Central air conditioning saturation is already high. Peak service occurs in winter. Altitude derating and fresh-air intake during inversions shape proper sizing and ventilation choices.

The shortlist

This shortlist is built from public listing data, not a review of work performed. Companies are ranked by a Bayesian-adjusted rating that pulls each star rating toward the national mean of 4.764 until the firm has enough reviews to stand on its own. Small tie-breakers favor a public website, HVAC-specialist listing, and published 24/7 availability.

Davis Air Tec

Davis Air Tec operates from 627 S 600 W, Hurricane, UT 84737. Its phone number is (435) 635-4451. The firm is listed as a general contractor without 24/7 availability. Its raw rating of 5.0 from 127 reviews receives a modest downward Bayesian adjustment to 4.995 because the national mean sits at 4.764; the review count is large enough to keep the drop under 0.01. These figures cannot reveal how the company manages winter ventilation requirements unique to the Wasatch Front.

Alta Air

Alta Air is located at 1230 W 2600 S, Woods Cross, UT 84087. Its phone number is (385) 376-3403. The general-contractor listing includes published 24/7 availability. Its raw rating of 4.9 from 279 reviews is pulled down 0.047 points by the Bayesian adjustment to 4.947; the larger review volume limits movement toward the 4.764 national mean. The numbers supply no information on how the firm handles altitude derating for equipment in this market.

Utah's Best Home Pros

Utah's Best Home Pros is based at 5464 S 1900 W Ste 6, Roy, UT 84067. Its phone number is (385) 324-1211. The general-contractor entry lists 24/7 availability. A raw rating of 4.9 from 181 reviews moves downward 0.041 points under Bayesian adjustment to reach 4.941. The review depth keeps the score close to the raw value. These statistics do not indicate experience with local inversion-driven filtration needs.

High Country HVAC, Inc.

High Country HVAC, Inc. works from 705 N 1000 W Ste 9, Centerville, UT 84014. Its phone number is (801) 797-0064. The listing shows a general contractor without 24/7 hours. Its raw rating of 4.9 from 433 reviews receives a Bayesian adjustment of 0.031 points downward to 4.931; the highest review count among the seven firms produces the smallest shift toward 4.764. The data set cannot show how the company sizes systems for the 5000 heating degree days.

Craig's Services

Craig's Services is located at 315 N 200 W, Bountiful, UT 84010. Its phone number is (385) 446-2031. The general-contractor category does not list 24/7 availability. A raw rating of 4.8 from 405 reviews is adjusted downward 0.062 points to 4.838. The substantial review volume limits the pull toward the national mean. These numbers offer no insight into the contractor's approach to evaporative cooling options in dry summers.

Mountain Home Services

Mountain Home Services operates from 8720 Monroe St, Sandy, UT 84070. Its phone number is (385) 240-3418. The general-contractor listing shows no 24/7 availability. Its raw rating of 4.8 from 74 reviews receives a Bayesian adjustment of 0.066 points downward to 4.83. Fewer reviews allow greater movement toward 4.764 than firms with hundreds of reviews. The figures cannot address how the company meets local business-license rules inside individual cities.

Smedley Service

Smedley Service is based at 857 Marshall Way N Unit d, Layton, UT 84041. Its phone number is (801) 738-8150. The general-contractor entry includes published 24/7 availability. A raw rating of 4.7 from 209 reviews is adjusted upward 0.068 points to 4.768 because the score sits below the national mean; the review count still allows noticeable movement. These statistics do not indicate whether the firm maintains the required DOPL classifications for the work it performs.

How to Choose an HVAC Contractor

Verify the contractor holds an active S350 license through the Utah DOPL Construction Business Registry. Confirm whether the city where the work will occur also requires a separate business license. Compare review counts after Bayesian adjustment rather than raw stars alone. Ask how the installer accounts for altitude derating and winter inversion ventilation. Request references from recent local installations in the same climate zone.

Installed Costs in Davis County

Published data list a typical full-system install at $9,550 with a range of $8,600 to $10,500. A separate 2025 invoiced data set reports an average of $18,497 and an upper quartile of $27,600. The two sources therefore differ substantially on realized project costs. Labor is stated at $110 per hour. Permit fees range from $100 to $350. Both sources are referenced because the gap itself supplies useful information about price variability in the county.

Licensing and Permits

HVAC contractor licensure occurs at the state level through the Utah Department of Commerce — Division of Occupational and Professional Licensing. The relevant classification is S350 for HVAC Contractor; a B100 General Building contractor may also perform HVAC work on single-family homes or multi-family buildings up to four units. DOPL requires general liability insurance with limits set by rule. Permits for equipment changeouts are issued by the local city or county building department rather than the state. Some cities further require a municipal business license before a contractor may work inside city limits.

Incentives

The Utah Home Energy Rebates program remains conditionally approved with launch delayed. A planned $8,000 heat-pump rebate is the largest state incentive listed. No state tax credit exists. Utility programs from Rocky Mountain Power and Dominion Energy Utah offer $200 to $1,500. Participation in those utility programs requires use of a network contractor. No federal residential HVAC tax credit applies in 2026. Homeowners should therefore prioritize contractors already enrolled in the wattsmart and ThermWise networks if they intend to pursue utility rebates.
