How to Start an HVAC Business in Utah: DOPL Contractor Classification and Experience

If you plan to run heating, ventilation, and air conditioning work in Utah, the state license is the first gate you have to clear. The Division of Professional Licensing (DOPL) now licenses HVAC contractors under the H100 (HVAC Contractor) classification. That rule took effect March 30, 2026, and since April 20, 2026, applications submitted or postmarked on or after that date fall under H100, which replaced the older S350 HVAC class. If you have been searching for a utah hvac license or an hvac license utah, this guide walks through what the state requires, in order, along with the costs you can verify and the ones you still need to confirm.

Scope note: This article is informational, not legal or tax advice. DOPL rules, forms, and fees change, so confirm anything that affects your filing with the agency before you submit or pay.

What You Need Before You Start

Gather these items before you open the application. A missing document usually means a stalled file, and it can cost you weeks.

• A qualifier who holds RMGA certification or an equivalent certification. The qualifier is the individual whose credentials the company relies on, so choose this person carefully.
• Passing results for the Utah Business and Law Exam and the HVAC (H100) Exam, both taken by the qualifier.
• Two years of HVAC-specific work history, with W-2 forms for each year as proof.
• Supporting documents showing wages and the employer relationship if a payroll agency or professional employer organization (PEO) issued your W-2s.
• Insurance certificates that meet DOPL's contractor minimums of $1 million per occurrence and $2 million aggregate.
• Entity paperwork, such as a Certificate of Organization for an LLC or Articles of Incorporation for a corporation.
• A Utah street address for the business and a registered agent with a Utah street address.
• Payment for DOPL and state filing fees. Confirm the current DOPL amounts with the agency first, because this article does not state them as settled figures.

Step-by-Step: Getting Your Utah HVAC Contractor License

Step 1: Confirm You Are Applying Under H100, Not S350

The S350 HVAC class is the older classification. Applications submitted or postmarked on or after April 20, 2026 must meet the H100 requirements. New application forms were released on April 20, 2026, so do not start from a packet you downloaded earlier or from an old form a colleague passed along. If you already hold an S350 license, call DOPL at (801) 530-6628 and ask how that license converts to H100 and whether you must take any action. Do not assume the conversion is automatic.

Step 2: Document Two Years of HVAC-Specific Experience

H100 requires two years of HVAC-specific experience, verified by W-2 forms. The rule asks for HVAC work specifically, so your records should show HVAC duties in your job titles and descriptions. Request W-2s from each employer where you did that work, and keep copies in a folder with the dates of employment. If a payroll agency or PEO issued your W-2s, include the supporting documents that show the relationship and your wages. Ask DOPL whether 1099 subcontract income can be used, because the verification path described for H100 is W-2 forms, and you should not assume other records will count.

Step 3: Get the Qualifier's Certification and Pass Both Exams

The qualifier must hold RMGA certification or an equivalent certification. The same person must pass two exams: the Utah Business and Law Exam and the HVAC (H100) Exam. Schedule these early, because the results go directly into your application. Before you spend money on a course or a certification, ask DOPL which credentials count as equivalent to RMGA, since that equivalency question is one to confirm with the agency.

Step 4: Buy Insurance That Meets the Minimums

DOPL's contractor insurance minimums are $1 million per occurrence and $2 million aggregate. Ask your agent for a certificate that shows both limits, and read each line of the policy rather than relying on the verbal summary. A policy that clears the per-occurrence limit but falls short on the aggregate does not meet the minimum. Premiums depend on your trade mix, payroll, and claims history, so get quotes from more than one carrier before you commit.

Step 5: Form the Business Entity

Utah has no statewide general business license. The first state step is registering your entity, and it is a registration, not a license. Most small HVAC shops choose an LLC, which is formed by filing a Certificate of Organization with the Utah Division of Corporations and Commercial Code at businessregistration.utah.gov. The filing fee is $59. Most online filings are processed and approved instantly. Filings that need manual review are stated at 2 to 4 business days, and the Division has posted 7 to 10 business days during backlogs.

Your LLC name must contain the words "limited liability company" or "limited company," or an abbreviation such as LLC, L.L.C., LC, or L.C. The name must be distinguishable from existing entity, reserved, registered, and assumed names on the Division's records, and it may not suggest that your company is a state agency or political subdivision. If you need time to finish the paperwork, you can reserve a name for 120 days for $22 through the Division's online registration instructions.

By default, an LLC is taxed as a partnership or sole proprietorship, and income passes through to the members and is taxed at Utah's flat individual income tax rate (4.45 percent for tax years beginning on or after January 1, 2026). An LLC that elects corporate treatment pays the 4.45 percent corporate franchise and income tax (2026), with a $100 minimum tax. A corporation files Articles of Incorporation with the same $59 filing fee. The entity choice affects taxes, liability, and ownership, so talk to a CPA before you decide.

Every registered entity must name a registered agent for service of process. The agent needs a Utah street address, and a PO box may be listed only in addition to a street address. The agent can be an individual, a registered business in good standing, or a commercial registered agent. Commercial registered agent registration costs $52.

Annual renewal is the yearly filing. The $18 renewal is due one year from the registration date and every year after that. The renewal window opens 60 days before the anniversary date, and a late renewal carries a $10 fee. Put the anniversary date on your calendar the day you register.

Step 6: Register a DBA If You Will Use a Different Name

If you will operate as something other than your legal name, such as Example Comfort Heating rather than your own LLC name, file an assumed name (DBA) registration. In Utah, a DBA is filed with the state Division of Corporations and Commercial Code, not with the county. The registration costs $22. Check the Division's DBA page for the renewal term and fee. Filing details are at the Division's DBA page.

Step 7: Plan for the Fingerprint Background Check

A fingerprint-based background check requirement starts January 1, 2027. Ask DOPL whether it applies to your application date and who must submit fingerprints. Plan for it either way, so an application does not stall on a requirement you did not expect.

Step 8: Submit the DOPL Application on the New Forms

Use the application forms released April 20, 2026. Assemble the qualifier's certification and exam results, your W-2 packet, the insurance certificates, and the entity documents into one submission. Before you pay, confirm three things with DOPL at (801) 530-6628: the current application fee, the current license fee, and the conversion process for existing S350 holders. Keep your confirmation number and every receipt.

Step 9: Get Your Local Business License and Sales Tax License

Your state registration does not allow you to work in every town. A city or town business license comes from the jurisdiction where your business is located or operating. Outside city limits, the license comes from the county. A city license does not transfer to another city, so if you operate in more than one jurisdiction, confirm whether each one requires its own license. Fees vary by jurisdiction, so check with the city or county office before you open.

If your business sells taxable goods, such as equipment or parts sold to customers, you need a separate Utah sales tax license from the Utah State Tax Commission. Register through the TAP system at the Tax Commission's TAP registration page. The state sales tax rate is 4.85 percent, and combined state and local rates run from 6.35% to 9.55% depending on the jurisdiction. Whether your labor and installation charges are taxable is a question for the Tax Commission or a CPA, and this article does not settle it.

Common Mistakes to Avoid

• Filing under S350 or on an old form. Confirm the H100 path and the forms released April 20, 2026 before you start.
• Counting experience you cannot document. W-2s are the verification path, so keep them for every year you claim.
• Assuming PEO or payroll agency history needs no extra paperwork. Gather the supporting documents at the start, not after a request from DOPL.
• Buying the minimum insurance quote without reading the limits. Both the per-occurrence and aggregate figures must meet the requirement.
• Treating the qualifier as a formality. The certification and exams sit with that person, so ask DOPL what a change in qualifier would mean for your license.
• Carrying a city license across city lines. A city license does not transfer, so confirm each jurisdiction where you work.
• Missing the annual renewal. The renewal is $18, and a late renewal adds $10.
• Skipping the sales tax question. Do not assume installation work is outside sales tax. Ask the Tax Commission or a CPA.

Expected Results

Once your state license, entity filing, local business license, and any tax registration are in place, many owners find it easier to bid on HVAC work, answer customer and insurer questions, and keep a clean paper trail for permits and inspections. The license may help you compete for jobs that require a licensed contractor, but it does not guarantee any specific volume of work or income. Results depend on your market, pricing, crew, and how well you run the business. Treat the license as the start of the process, not the finish line.
