Texas requires HVAC contractors to hold a state license through the Texas Department of Licensing and Regulation (TDLR) before they install, service, or maintain most air conditioning and refrigeration systems. Meeting these requirements protects both contractors and customers by ensuring work is performed safely, legally, and to current industry standards.
Overview of TDLR HVAC Licensing
The TDLR regulates Air Conditioning and Refrigeration (ACR) contractors at the state level, so anyone advertising or performing HVAC contractor work must comply with TDLR ACR regulations. Contractors typically hold an ACR contractor license and may also employ registered technicians who work under their supervision.
TDLR issues licenses specifically for contractors who install, repair, or maintain systems related to air conditioning, heating, and refrigeration, including many residential and commercial HVAC systems. ACR companies must also employ a licensed ACR contractor at each permanent location to oversee regulated work and maintain compliance.
License Classes and Endorsements
Texas offers two main classes of HVAC contractor license: Class A and Class B. A Class A license allows work on HVAC systems of any size or capacity, making it the most flexible option for contractors who handle large commercial or mixed portfolios. Linking directly to TDLR’s application page helps clarify these Class A and Class B license distinctions for prospective contractors.
A Class B license limits the holder to cooling systems of 25 tons or less and heating systems of 1.5 million BTUs per hour or less, which still covers many typical residential and light commercial projects. Contractors can also select endorsements such as Environmental Air, Commercial Refrigeration and Process Cooling or Heating, or Combined, which define the types of HVAC work they are authorized to perform.
Core Eligibility and Experience Requirements
To qualify for a TDLR ACR contractor license, applicants must meet age, experience, and documentation standards. Applicants must be at least 18 years old, and they need several years of practical HVAC experience working under a licensed contractor before they can even apply.
In most cases, candidates must show either 48 months of practical air conditioning and refrigeration-related work within the past 72 months under a licensed ACR contractor, or 36 months of supervised experience in the past 48 months if they have held a Texas ACR technician certification for at least the previous 12 months. Resources like this step‑by‑step Texas HVAC license guide can help candidates understand how to document their experience and prepare their application.
Exceptions and Alternate Paths
TDLR allows limited exceptions to the standard experience path for certain qualified professionals. Applicants may qualify for reduced or modified experience requirements if they hold a degree, diploma, or certification in air-conditioning and refrigeration, have a mechanical engineering degree or engineering license, have applicable military training, or work in industrial process cooling or heating.
These exceptions do not remove the need to follow TDLR’s application and examination processes, but they can make it easier for experienced engineers, veterans, or industrial specialists to transition into a licensed contractor role. Applicants using one of these paths must still provide documentation that supports their education or specialized training.
Application, Exam, and Continuing Obligations
Once experience and eligibility are in place, prospective HVAC contractors submit the Air Conditioning and Refrigeration Contractor License Application and pay the required fee, which is currently listed by TDLR at 115 dollars. The completed Experience Verification Form and any supporting documents should be included with the application so TDLR can confirm the applicant’s qualifications.
If the application is approved, TDLR notifies the exam provider and authorizes the candidate to schedule the ACR contractor exam, which covers both technical HVAC topics and trade-related business rules. Applicants can also refer to third‑party Texas HVAC license requirement summaries for additional context on exams, insurance, and renewals, but TDLR remains the official source.
