Verify the license before anything else
Utah HVAC contractors are licensed at the business level by the Utah Division of Professional Licensing (DOPL) Contractors Board, most commonly under the S350 HVAC/Mechanical Contractor classification 1. Ask for the license number and verify it directly on DOPL's online lookup rather than taking a business card at face value, and confirm whoever will handle refrigerant carries current EPA Section 608 certification.
Get quotes that reflect Lehi's climate, not a generic template
A quote that doesn't mention Lehi's 95-100F dry summer peaks, hard winter cold snaps, or whether your home has evaporative or refrigerated cooling is likely a copy-paste estimate. Ask for a real Manual J load calculation, and ask directly whether the proposed equipment is sized for both extremes rather than just one season.
Ask about permits up front
A legitimate contractor should tell you, unprompted, that the job needs a mechanical permit filed through Lehi City's Building Permit Submittal Portal and should include that in their timeline and price 2. If a contractor suggests skipping the permit to save time or money, treat that as a serious red flag.
Compare at least two or three written quotes
Get itemized, written quotes rather than verbal ballpark numbers, and make sure each quote specifies equipment brand, model, tonnage, and efficiency rating so you're comparing equivalent systems rather than just bottom-line prices.
Ask about warranties and utility rebates
Ask what manufacturer and labor warranties come with the installation, and whether your chosen equipment qualifies for current Rocky Mountain Power or Dominion Energy Utah rebate programs — a contractor familiar with local rebate paperwork can save you real money on the final cost.
Typical cost ranges
| Initial in-home estimate/consultation | $0 - $100 |
| Manual J load calculation (standalone) | $100 - $300 |

| Heat pump replacement quote range | $6,500 - $12,500 |
| Annual maintenance plan | $150 - $350 |
| Second-opinion diagnostic visit | $80 - $170 |
Ranges are general estimates gathered from homeowner-reported quotes, not an offer or a quote for your project.
Common questions
How do I verify an HVAC contractor's license in Utah?
Ask for their Utah DOPL license number and classification (usually S350) and check it against DOPL's online contractor license lookup.
Should I get multiple quotes for HVAC work in Lehi?
Yes, get at least two or three written, itemized quotes so you can compare equipment specs, warranty terms, and whether each contractor plans to pull the required mechanical permit.
What's a red flag when hiring an HVAC contractor?
A contractor who avoids discussing permits, gives only a verbal estimate, can't produce a license number, or pressures you to sign same-day without a written quote.
Does the contractor or I pull the mechanical permit?
A qualified contractor typically pulls the mechanical permit themselves through Lehi's Building Permit Submittal Portal as part of the job; confirm this in writing before work starts.
Why does Lehi's climate matter when choosing a contractor?
A contractor unfamiliar with Lehi's dry summer heat, winter cold snaps, and mix of evaporative and refrigerated cooling may under- or over-size equipment or skip humidity considerations that matter here.
Should I ask about rebates before signing a contract?
Yes — ask whether your chosen equipment qualifies for current Rocky Mountain Power Wattsmart or Dominion Energy Utah ThermWise rebates, since a knowledgeable contractor can help you capture those savings.
