WHAT CREDENTIALS OR LICENSING SHOULD AN HVAC TECHNICIAN IN TEXAS HAVE?

A Clear Guide for Homeowners in Austin & the Central Texas Hill Country

When your air conditioner stops cooling in the middle of a Texas summer, you don’t just need help, you need the right help.

And in a field where experience and safety are critical, homeowners often ask:

“What credentials should I look for in a Texas HVAC technician?”

HVAC work involves electrical systems, refrigerants, gas lines, safety controls, and high-pressure components. In Texas, technicians must meet strict state licensing and training standards to work legally and safely.

Greg Gonzales, owner of Greg’s Heating & Air, says:

“If someone isn’t licensed in Texas, they shouldn’t be touching your HVAC system — period.”

1. TEXAS HVAC TECHNICIAN LICENSING REQUIREMENTS (TDLR CREDENTIALS)

All HVAC technicians in Texas must be licensed or registered through TDLR.

REGISTERED TECHNICIAN (TECH REGISTRATION)

Entry-level requirement for anyone working under a licensed HVAC contractor.

Must:

• Be officially registered with TDLR

• Work under a licensed ACR Contractor

• Follow Texas safety and mechanical codes

CERTIFIED TECHNICIAN

A step above registration.

Requires:

• Documented HVAC experience

• Formal training

• Passing a certification exam

LICENSED ACR CONTRACTOR (THE COMPANY LICENSE)

Required for pulling permits and legally operating an HVAC business.

Class A: Can work on any size HVAC system.

Class B: Limited to residential-size systems up to 25 tons.

2. EPA SECTION 608 CERTIFICATION (REQUIRED BY FEDERAL LAW)

Any technician who handles refrigerants must hold EPA Section 608 Certification.

Types:

• Type I — Small appliances

• Type II — High-pressure systems (most residential units)

• Type III — Low-pressure systems

• Universal — Covers all systems (preferred)

Greg explains:

“If a tech handles refrigerant without an EPA card, it’s illegal. No exceptions.”

3. ONGOING TRAINING & MANUFACTURER EDUCATION

Technology evolves quickly — especially with new refrigerants, variable-speed equipment, and updated efficiency standards.

Qualified technicians receive:

• Continuing education

• Factory training for major brands

• Instruction on modern diagnostic tools

4. BACKGROUND CHECKS & PROFESSIONAL STANDARDS

Reputable HVAC companies perform:

• Background checks

• Drug screenings

• Driving record checks

Technicians should:

• Arrive in uniform

• Carry ID

• Respect your home

• Explain issues clearly

5. INSURANCE COVERAGE (PROVIDED BY THE COMPANY)

HVAC companies in Texas must carry:

• General liability insurance

• Workers’ compensation or equivalent coverage

This protects homeowners if:

• Property is damaged

• A worker is injured onsite

6. HOW TO VERIFY A TECHNICIAN OR COMPANY

You can verify a Texas HVAC license quickly by:

• Searching the TDLR license lookup website

• Asking the technician for their license card

• Looking for the company’s license number on vehicles or websites

Greg says:

“If someone hesitates when you ask about licensing, that’s a red flag.”
