HVAC License in Texas: Fees, Requirements & Startup Costs



Quick answer: Texas HVAC contracting is regulated by the Texas Department of Licensing and Regulation (TDLR). An individual Air Conditioning and Refrigeration Contractor license, with the appropriate Class A or B and endorsement, anchors the business. The official application fee is $115 under the TDLR application instructions; the chosen class also has a separately charged exam. City mechanical permits still apply.

Choose class and endorsement before selling work

Texas treats the ACR contractor credential as an individual license. The holder is responsible for the business’s work, so an entity filing alone does not establish contracting authority. Class A covers equipment without the Class B capacity limits. Class B is limited to cooling systems of 25 tons and under and heating systems of 1.5 million BTU per hour and under, as described in the TDLR ACR record. Match the planned equipment to the class before advertising commercial work.

The endorsement also matters. Environmental Air Conditioning, Commercial Refrigeration, and Process Cooling or Heating describe different work. A repair offer that grows into commercial refrigeration should be reviewed against the license endorsement rather than assumed to be covered because the technician can perform the task. Keep a written service list that the license holder approves.

Licensing in Texas

Jurisdiction: state

Authority: Texas Department of Licensing and Regulation (TDLR) - Air Conditioning and Refrigeration Contractors

HVAC contractors are licensed statewide by TDLR as Air Conditioning and Refrigeration (ACR) Contractors (Occ. Code ch. 1302). The ACR contractor license is an individual license; the licensee is responsible for the business's work. Local jurisdictions handle mechanical permits.

Data notes

exam.fee left null because it varies by class ($74 Class A, $60 Class B; listed in fees). Exam fees come from PSI's TDLR ACR Candidate Information Bulletin (effective Sept 1, 2026), paid directly to PSI per the TDLR application form. Technician registration/certification (for employees) not covered here.

What the application asks the contractor to prove

The researched application path calls for practical ACR experience under a licensed contractor, with an alternative route for a person who has held ACR technician certification and accumulated the specified practical experience. The applicant then takes the exam for the selected class and endorsement. The PSI bulletin lists different charges for Class A and Class B exams, so a launch budget should use the chosen route rather than combining them.

Texas requires class-specific liability coverage. The application page gives separate occurrence, aggregate, and products-completed operations limits for Class A and Class B. Obtain an insurance certificate that matches the proposed class before expecting the credential to be ready. The researched application page did not state a bond requirement. An applicant with specified criminal-history answers may need an additional questionnaire.

Renewal and local job control

The contractor credential renews annually, with continuing education described in the TDLR renewal guidance. Put renewal and insurance dates on the operating calendar so an accepted job does not outlast the authority to perform it. The license record here does not analyze employee technician registration or certification; verify staffing rules with TDLR as hiring plans become concrete.

Texas cities handle mechanical permits and inspections. Ask the city for each job address which work needs a permit, who must apply, and how inspections are scheduled. A state license does not establish a citywide permit policy. Add permit time and inspection returns to the estimate when replacing equipment or changing a system.

Use the Texas budget preset

A Texas service startup may prioritize diagnostic instruments, refrigerant handling gear, and common replacement parts. Installation work adds equipment ordering, delivery, access, commissioning, and a larger gap between purchases and customer collection. Edit the preset for the actual class, vehicle, coverage quote, and services. The startup guide explains why those choices move the opening budget; the pricing guide connects them to customer charges.
