Understanding Texas HVAC Licensing: The Foundation

The Texas HVAC market is one of the strongest in the country, driven by extreme weather conditions, rapid urban growth, and year-round demand for heating and cooling services. But with that opportunity comes a well-structured (and strictly enforced) HVAC licensing system managed by the Texas Department of Licensing and Regulation (TDLR). Whether you’re just getting started or planning to launch your own company, understanding the full scope of Texas HVAC license requirements is essential.

Who Needs an HVAC License in Texas?

Anyone performing air conditioning and refrigeration (ACR) work in Texas must hold appropriate HVAC license issued by the TDLR. This includes installation, maintenance, repair, and alteration of HVAC systems. The state’s definition is comprehensive and covers virtually all professional HVAC activities, requiring licensing for the following:

  • Registered Technicians – the entry point for new workers (comparable to apprentices),
  • Certified Technicians – advanced tradespeople who pass a licensing exam (similar to journeymen), and
  • Contractors – fully licensed professionals who can operate independently and pull permits.

Importantly, every HVAC business must have at least one licensed ACR contractor tied to each permanent location. Unlicensed individuals are not allowed to advertise HVAC services, supervise installs, or pull permits under any circumstances.

Who’s Exempt from HVAC Licensing in Texas?

Texas law provides several specific exemptions where a license or registration is not required. These include:

  • Homeowners working on their own single-family residence (must still follow local code and permit rules)
  • Licensed electricians performing electrical work as part of HVAC installation
  • Licensed plumbers working on HVAC systems that involve water (like hydronic systems)
  • Employees of regulated utilities working on utility-owned infrastructure
  • New construction workers installing full HVAC systems under the supervision of a licensed contractor
  • Building maintenance staff employed directly by a property owner, performing routine HVAC upkeep
  • Specific equipment exemptions, including:
    • Window units and portable systems under 3 tons
    • Refrigerators, freezers, and ice machines
    • Automotive HVAC (vehicle air conditioning systems)
    • Kitchen vent hood installation
    • HVAC in manufactured homes (if done by a licensed mobile home installer)

These carve-outs are helpful, but they don’t mean you can bypass the system entirely. If you’re advertising services to the public or getting paid to install or repair HVAC systems, you need to be licensed.

Who Regulates HVAC Licensing in Texas?

The Texas Department of Licensing and Regulation oversees all HVAC licensing (Air Conditioning and Refrigeration, or ACR), working in conjunction with the Air Conditioning and Refrigeration Contractors Advisory Board. This structure ensures both technical competency and industry input in regulatory decisions. The rules and regulations are codified under:

HVAC license applications and renewals are handled through the TDLR website.

Background Check Requirements for HVAC Licensing in Texas

All HVAC licenses in Texas including ACR registered technician, ACR certified technician, and ACR contractor licenses are subject to a criminal background check conducted by the Texas Department of Licensing and Regulation (TDLR). This check is required to ensure that license holders meet the state’s standards for public trust and safety.

Having a criminal record doesn’t automatically disqualify you, but certain offenses may affect your eligibility. TDLR evaluates each case individually, considering factors like the nature of the offense, how long ago it occurred, and whether it relates to your ability to perform HVAC work safely and ethically. If you’re concerned about past convictions, you can request a criminal history evaluation letter before submitting your application to see if your background might be an issue.
