How to Get Licensed

5 STEPS

Meet Education and Experience Requirements

For Class A license: accumulate 8,000 hours of documented HVAC field experience, or equivalent (4-year apprenticeship + 1 year field work, for example). For Class B license: accumulate 4,000 hours of documented field experience. Both require high school diploma or GED. Hours must be verified by employers and tracked on TDLR forms. Document everything—timesheets, supervisor sign-offs, project descriptions. This step typically takes 2-4 years.

01/05

Obtain EPA 608 Certification

Pass the EPA 608 exam covering safe refrigerant handling. Minimum Type II certification required (small appliances); Type I (high-pressure systems) and Type III (low-pressure systems) also recommended. Exam is offered through HVAC training centers across Dallas. Cost is typically $100-$200. Certification is required before you can legally handle refrigerant and must be renewed every 5 years. Keep your certificate on file.

02/05

Pass the HVAC Trade Exam

Register with TDLR and schedule the HVAC trade exam (contractor exam for Class A/B). Exam covers code knowledge, system design, installation standards, and safety protocols. Available through licensed testing centers in the Dallas area. Cost is $150-$300 per attempt. You must score at least 70% to pass. Study materials are available through TDLR and prep courses are offered by trade schools. Allow 30-45 days from registration to test date.

03/05

Apply for Your HVAC Contractor License

Submit your completed application to TDLR with proof of experience hours, high school diploma, EPA 608 certification card, and passing trade exam score. Application fee is approximately $300-$400. TDLR processes applications in 10-20 business days. You'll receive a license number and physical license card valid for 2 years. Class A contractors can pull permits and operate independently; Class B contractors must work under a licensed Class A.

04/05

Complete Biennial Renewal with Continuing Education

Every 2 years, renew your HVAC license by submitting a renewal application to TDLR and proof of 16 hours continuing education. Continuing education must cover HVAC code, safety, or technical topics from approved providers. Cost for renewal is approximately $250-$350. Renewal applications are due 30 days before your license expiration date. Non-renewal results in license suspension and inability to legally perform HVAC work or pull permits.

About This Market

UPDATED APR 2026

Dallas HVAC market is high-volume and competitive. You've got roughly 8,320 licensed HVAC establishments across Texas, and Dallas claims a significant chunk of that—metro area alone sees constant turnover of aging residential units and steady commercial retrofit demand. Summer peaks hard: heat-wave seasons drive emergency calls and replacements. Residential jobs dominate (AC unit swaps, furnace installs), but commercial HVAC retrofits and new construction pull solid margins if you can bid them right. Ductwork issues are endemic in older Dallas housing—poor insulation, leaky seals, load calculations off by a mile. Material costs float with copper and refrigerant markets. Labor burns fast in peak season, so crew scheduling and equipment availability are real bottlenecks. Median HVAC tech in the US makes $59,134 annually; Dallas tracks near that, sometimes higher due to demand.

To work this market, you need a Class A or Class B HVAC license from TDLR—no shortcuts. Class A contractors can operate independently and pull permits; Class B can only work under a licensed Class A. EPA 608 certification is non-negotiable for anyone touching refrigerant, and inspectors verify it on-site. Dallas Building Department doesn't play loose on permits—inspect at rough-in and final. Get your general liability and workers' comp squared away before your first job or you're done before you start. Peak season runs May-September; that's when you'll see 60% of your volume, so staff and schedule accordingly. Winter has a secondary spike when folks realize their furnace doesn't work in a rare cold snap. Know the code: Texas follows International Energy Conservation Code and EPA protocols strict. Quotes take 2-5 days in normal season, 5+ in summer. Be realistic on timelines and don't oversell your crew.
