Who Needs a License in Utah?
Every contractor, business, or sole proprietor who installs, repairs, fabricates, or maintains HVAC or refrigeration systems in Utah is required to hold a current H100 HVAC Contractor license. Utah law does not provide any dollar-value exemption for HVAC work: even the smallest residential job requires a license if the work falls under the HVAC definition.
According to Utah Admin. Code R156-55a-301g, the scope for HVAC includes the installation, alteration, repair, or replacement of warm-air heating, ventilation, air conditioning, refrigeration systems, and related duct work. Therefore, if your project involves these systems, HVAC license requirements in Utah mean you must be properly licensed.
There are no "handyman" or "owner-builder" exceptions expressly listed for HVAC projects. However, contractors holding a B100 General Building license may self-perform HVAC work limited to single-family or multifamily dwellings with up to four units. For HVAC work involving electrical, plumbing, or natural gas, you must either hold additional relevant licenses (E200/E201 for electrical, P200/P201 for plumbing) or staff a certified RMGA natural gas technician for relevant gas line work.
If you are an employee working under a licensed HVAC contractor, you do not need your own H100 license, but the supervising contractor's qualifier must oversee the work. As a result, if you want to bid jobs, supervise crews, or subcontract, you must satisfy all HVAC license requirements in Utah and become licensed.
HVAC License Types
Utah issues several contractor license classifications that cover HVAC work. The primary and only current specialty classification is H100 HVAC Contractor. However, legacy S350 licenses remain valid (automatically converted to H100) through November 30, 2027, if held in good standing as of January 1, 2026.
H100 HVAC Contractor: The current specialty license for all commercial and residential HVAC and refrigeration contracting after April 20, 2026. Allows broad scope HVAC work (fabrication, installation, repair, maintenance of HVAC and refrigeration systems; excludes electrical and plumbing unless holding those licenses or teaming with qualified technicians).
S350 (Legacy): Previously issued for HVAC work. All S350 licenses in good standing as of January 1, 2026, are automatically converted to H100 classification until their next expiration (November 30, 2027). After that date, the legacy S350 will be invalid, and holders must fully comply with new H100 requirements.
B100 General Building Contractor: Allows HVAC work for single-family and up to four-unit dwellings only. Contractors performing broader commercial HVAC must have the H100 classification.
HVAC license requirements in Utah do not allow you to mix certain specialty licenses (e.g., combining R101 with others), and you can hold up to three specialty classifications plus a general license. Each license requires a separate qualified individual (qualifier) and separate proof of experience, insurance, and bonding.
HVAC License Requirements in Utah: How to Get Licensed
To earn your H100 HVAC Contractor license, you must complete several specific steps, each with strict supporting documentation.
Verify Experience and Find Your Qualifier
Verify Experience Eligibility: You must have at least 4,000 hours (two years) of documented HVAC-specific work within the past five years, supported by W-2s, K-1s, or tax returns. Self-certification is not accepted. If you are applying as a qualifier through the plumbing category, you must be a licensed plumbing journeyman or master (residential or general).
Identify a Qualifier: Every company or sole proprietor must designate a qualified individual meeting the experience requirement. Qualifiers must be either the applicant themselves or a full-time employee, owner, or manager of the company. Grandfathered interim qualifiers (from S350) are accepted only until November 30, 2027.
Prepare Documentation and Take Exams
Gather All Documentation: Collect all required documents: proof of experience (see above), proof of RMGA (Rocky Mountain Gas Association) or equivalent certification for gas work, proof of passing scores for both the Utah Business & Law and H100 trade exams, certificate of general liability insurance ($1 million per occurrence/$3 million aggregate), a license bond ($15,000 minimum), and identification documents (SSN, ITIN, resident alien number, or passport with intent-to-comply letter for foreign applicants). If applying by endorsement from another state, gather license verification and ownership documentation.
Take Required Exams: Schedule and pass the Utah Business & Law and H100 trade exams with ProV Exams. You do not need pre-approval to sit these tests. Bring proper photo ID and arrange for ADA accommodations in advance if needed.
Submit Application and Await Licensing
Fill Out Application: Download the “contractor all classifications” form from DOPL’s site. Complete all sections, attach supporting documents, and sign as required. See the official checklist to avoid omissions.
Submit the Application and Fee: Submit your completed application and pay the $175 fee (as of April 2026, see DOPL fee schedule) electronically via the My License One portal or by mail to DOPL’s office address (see checklist for address). The Division recommends keeping a copy for your records.
Wait for Processing: Allow up to four weeks for the Division to review your application. If you receive no updates within four weeks, follow the instructions in DOPL’s contractor FAQs for application status requests.
Receive Your License: If approved, you will receive confirmation by email or mail. Your license is active through November 30 of the next odd-numbered year. If denied, follow up as directed for deficiency correction or appeals.
For S350 Holders: No reapplication is necessary if the S350 was in good standing as of January 1, 2026; the conversion to H100 is automatic until the license expiration (November 30, 2027).
Application Requirements
To comply with HVAC license requirements in Utah, you must provide explicit details and documentation for each requirement listed below.
Experience and Age
You or your qualifier must have 4,000 hours of HVAC-specific work experience within the last five years. Acceptable documentation includes W-2 forms, K-1 partnership statements, or official tax returns. Self-certification, affidavits, or unsupervised experience are not accepted. The experience must be directly related to HVAC equipment installation, fabrication, service, or maintenance and be supervised by a licensed H100 (or S350, if during the legacy period) contractor. No explicit minimum age is listed, but you must have work eligibility.
Bond and Insurance
The state requires a minimum $15,000 contractor license bond for H100 licensees, as set in Utah Admin. Code R156‑55a‑602. The bond must be issued by a surety authorized in the U.S. Treasury Circular 570. In addition, your business must maintain general liability insurance of at least $1 million per occurrence and $3 million aggregate (in effect starting April 20, 2026). You must provide certificates or policy documentation before a license is issued and keep them current during licensure.
Background and Legal Status
Include your Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Alien Registration Number. If you are not a U.S. citizen or permanent resident, a passport and a signed letter attesting to your intention to become eligible are required. If applying by endorsement, also submit documentation proving at least 50% continuity of firm ownership in Utah and the state from which you are endorsing.
Supporting Certifications
RMGA certification or equivalent is mandatory if your firm will perform natural gas HVAC work. Only Certified Natural Gas Technicians can install or alter gas lines. This is documented by attaching proof from RMGA or an approved body.
Exams
To meet HVAC license requirements in Utah, you must pass two key exams: the Utah Business & Law exam and the H100 HVAC trade exam, both administered by ProV Exams.
Exam Types: Both exams are required for all new H100 applicants unless you are pursuing licensure by endorsement and receive a waiver for the Business & Law exam.
Provider and Scheduling: Exams are delivered through ProV at testing centers across Utah or online via Examroom AI. No pre-approval by DOPL is needed before you register to sit the exam.
Format: The H100 HVAC trade exam is a proctored, written test covering installation, repair, codes, and safety. The Utah Business & Law exam covers statutes, rules, contracts, and management. The Examination Handbook (not detailed in brief) outlines topics and materials to bring. You must present a valid, government-issued, photo-bearing ID that matches your application exactly.
Attempts and Accommodations: You may attempt each exam up to three times, with a minimum 30-day gap between attempts. If unsuccessful after three attempts, a 180-day waiting period applies before further retesting. ADA accommodations are available but must be arranged with ProV prior to exam registration.
After Passing: Once both exams are passed, ProV provides confirmation that you should attach to your application when submitting to DOPL.
See DOPL's Exam Information page for test scheduling details and any updates.

Renewal and Continuing Education
To keep an H100 HVAC Contractor license active, you must complete the requirements outlined below and renew by November 30 of every odd-numbered year.
Renewal Cycle and Deadlines
Your HVAC license expires on November 30 of every odd year (e.g., 2027, 2029). The Division recommends renewing promptly, as working on an expired license is unlawful and may result in penalties or enforcement actions. Late renewal incurs a $20 penalty, and a $50 reinstatement fee applies if your license has already lapsed and requires reinstatement.
Continuing Education (CE) Requirements
Utah requires all H100 licensees to complete six hours of CE per renewal cycle. At least three hours must be directly related to HVAC installation, repair, or replacement. In addition, at least three hours must be completed via "live seminar," meaning in-person or live broadcast, rather than self-paced online or correspondence.
CE courses must be approved by DOPL. To see approved courses, use Utah's CE Registry. CE providers have up to seven days after course completion to upload your credits. It is your responsibility to verify all credits are properly recorded in the registry prior to renewal. Failure to document full CE hours could delay your renewal or place your license in non-compliance.
License Lapse and Reinstatement
If you fail to renew by November 30, you may pay the $20 late fee during the grace period to retain licensure. If you miss this window, you face the $50 reinstatement fee in addition to the renewal fee. Practicing HVAC work without a current active license is unlawful in Utah and may incur disciplinary action.
Reciprocity
Utah does not offer direct license reciprocity with any specific state for HVAC contractors. However, there is an endorsement application pathway for out-of-state license holders.
If you currently hold an equivalent HVAC contractor license in another state, you may apply by endorsement if you have at least one year experience under that license and maintain at least 50% ownership continuity in both the out-of-state and Utah businesses.
You must provide official verification from the other state’s licensing board, plus documentation proving the required experience and ownership overlap (not more than 50% changed in the past year).
The Utah Business & Law exam may be waived for endorsement applicants if already passed in the original state (according to a Utah state bulletin). However, the H100 trade exam is still required unless you receive a specific waiver.
See the forms and checklists on the DOPL website, and contact DOPL if further guidance is needed for endorsement applications.
