HVAC License Requirements in Texas | House Escort - Local Home Service Professionals

Getting licensed as an HVAC contractor in Texas is a multi-step process managed by the Texas Department of Licensing and Regulation (TDLR). Understanding which license you need, how to qualify, and what the exam covers is the first step toward building a legitimate HVAC business in the state’s massive home services market.

Texas’s HVAC market is significant — with extreme summer heat (Austin regularly hits 100°F+), year-round air conditioning demand, and a booming construction market in metros like Houston, Dallas, and San Antonio, licensed HVAC technicians are in consistent demand.

HVAC License Types in Texas

TDLR administers several HVAC license categories. The two most relevant for contractors are:

Air Conditioning and Refrigeration Contractor License (ACR-Contractor)

This is the primary license for business owners who want to perform, supervise, or offer HVAC services commercially. The ACR-Contractor license allows you to:

Operate an HVAC contracting business
Pull permits for HVAC work
Supervise unlicensed employees performing HVAC work
Bid on residential and commercial projects

Requirements:

Pass the TDLR Air Conditioning and Refrigeration Contractor exam
Have qualifying experience (typically 4 years of practical experience, with at least 2 as a journeyman-level tech or similar)
Submit proof of insurance ($500,000 general liability + workers’ comp if you have employees)
Pay the license fee

Air Conditioning and Refrigeration Technician License (ACR-Technician)

This license is for individual technicians who perform HVAC work under the supervision of a licensed contractor. An ACR-Technician can:

Perform HVAC installation, maintenance, and repair
Work under a licensed ACR-Contractor

Requirements:

Pass the TDLR ACR Technician exam
Have 2 years of HVAC experience (can include apprenticeship or trade school)
Pay the license fee

EPA Section 608 Certification

While not a TDLR license, EPA Section 608 certification is federally required to purchase and handle refrigerants (R-410A, R-22, R-32, etc.). This is a separate certification from the EPA, administered through approved testing organizations. You must have EPA 608 before handling refrigerants — which means before you can do essentially any HVAC service work.

Type I: Small appliances
Type II: High-pressure appliances
Type III: Low-pressure appliances
Universal: All types (most useful for full HVAC contractors)

Universal 608 certification is what most Texas HVAC technicians pursue. Testing is available through HVAC training schools, community colleges, and authorized testing centers.

Experience Requirements

For ACR-Contractor: TDLR requires documentation of qualifying experience. The standard path:

4+ years in the HVAC trade, with at least 2 years in a role involving installation, service, repair, or maintenance of air conditioning and refrigeration systems
Experience should be documented via employer letters or pay stubs

For ACR-Technician:

2 years of hands-on HVAC experience
Experience can come from formal apprenticeship, trade school + work experience, or direct on-the-job training under a licensed contractor

Many Texas HVAC apprentices start by working for a licensed contractor, accumulating experience hours while learning the trade — then take the TDLR exam when eligible.

TDLR HVAC Exam Structure

The TDLR ACR exams are closed-book, multiple choice. Content areas include:

Electrical: Electrical systems, wiring, safety, motor controls
Refrigeration: Refrigerant types, refrigeration cycle, EPA 608 compliance, handling procedures
Air distribution: Duct design, static pressure, airflow calculations, balancing
Installation standards: Load calculations, ACCA Manual J/D/S methodology
Safety: OSHA standards, safety procedures, personal protective equipment
Texas regulations: TDLR rules, permit requirements, inspection procedures

Study resources:

TDLR publishes a candidate handbook with the content outline
HVAC Excellence, North American Technician Excellence (NATE), and ESCO Group offer study materials and practice tests
Community colleges and trade schools in Houston, Dallas, and other Texas metros offer exam prep courses

Fees and Renewal

License	Application Fee	Renewal Period	Renewal Fee

ACR-Technician	~$55	2 years	~$44
EPA 608 Cert	$20–$50 (varies by test center)	No renewal required	N/A

Verify current fees at license.tdlr.texas.gov — fees are subject to change.

Continuing education: Texas requires continuing education hours for ACR license renewal. The number of hours and acceptable courses are specified by TDLR. Plan for 8–12 hours of CE per renewal period.

Path from Unlicensed to Licensed Contractor

The typical progression for an HVAC professional in Texas:

Get EPA 608 — Before handling any refrigerants; can do this at a trade school or testing center
Work as an HVAC apprentice/helper — Gain hands-on experience under a licensed contractor; no TDLR license required at this stage
Accumulate 2 years of documented experience → Eligible for ACR-Technician exam
Pass ACR-Technician exam → Can now work as a licensed technician
Continue accumulating experience (total of 4 years) → Eligible for ACR-Contractor exam
Pass ACR-Contractor exam + meet insurance requirements → Can now operate your own HVAC business

Many HVAC technicians in Texas skip the Technician license and go directly to Contractor once they have 4 years of experience. Both paths work; the Contractor license is what you need to run your own business.

Running Your HVAC Business After Licensing

Once you’re licensed, the business infrastructure matters:

Insurance: Texas requires $500,000 general liability for ACR-Contractor. Workers’ comp is required if you have employees
Permits: You’ll pull building permits for installations — understand your local jurisdiction’s requirements (city of Houston, Dallas, Austin each have their own processes)
Pricing: See our Pricing Your Services Contractor Guide for how to set rates that cover overhead and generate profit
Finding clients: Build your client base on platforms where you keep 100% of your earnings

Frequently Asked Questions

How long does it take to get an HVAC license in Texas?

The experience requirement (2 years for Technician, 4 for Contractor) is the main timeline driver. Once you meet the experience threshold, the application and exam scheduling can typically be completed within 4–8 weeks. Total time from starting as an apprentice to holding an ACR-Contractor license is typically 4–6 years with consistent work experience.

Can I work as an HVAC technician in Texas without a license?

You can perform HVAC work as an unlicensed apprentice/helper under the direct supervision of a licensed ACR-Contractor. However, you cannot independently sell, install, or service HVAC systems without appropriate licensing. Working without a license when one is required is a TDLR violation subject to fines.

Does Texas recognize HVAC licenses from other states?

Texas has limited reciprocity for out-of-state HVAC licenses. Some states have mutual recognition agreements; others require Texas-specific exams regardless of prior licensure. Check the TDLR website for current reciprocity agreements. Technicians moving to Texas from other states should verify their credentials before starting work.

Do I need a separate license for commercial HVAC in Texas?

The ACR-Contractor license covers both residential and commercial HVAC. However, commercial work often involves larger, more complex systems (chilled water, large tonnage units, building automation) that may require additional certifications from manufacturers or NATE certifications to be competitive for commercial contracts.

What insurance do I need as a licensed HVAC contractor in Texas?

TDLR requires proof of general liability insurance ($500,000 minimum) for ACR-Contractor licensure. If you employ others, Texas requires workers’ compensation insurance (though Texas is one of few states where it’s technically optional — check current requirements). Commercial vehicle insurance for your work truck is a separate requirement. Most HVAC contractors also carry professional liability/errors and omissions insurance for added protection.
