Class C: Requires one year of experience; restricted to basic HVAC work under Class A or B supervision.
Restricted License: Available for those without experience; can only perform specific work under direct supervision.
Submit proof of EPA 608 certification, work experience documentation (with employer verification letters), high school diploma or equivalent, and the application fee. The TACB will verify your qualifications and may request additional documentation. Processing typically takes 4-8 weeks. Once approved, you'll receive your license number and certificate. All applications are submitted electronically through the TACB portal (Texas Occupations Code § 1302.002 and Texas Administrative Code Title 22 § 25.103).
Federal Requirements
HVAC contractors in Texas must comply with multiple federal requirements. Under the EPA's SNAP (Significant New Alternatives Policy) Rule (42 U.S.C. § 6001 et seq.), all technicians handling refrigerants must obtain EPA Section 608 certification before any work can begin. This certification confirms competency in proper refrigerant handling, recovery, and recycling to prevent ozone layer damage.
Under OSHA regulations (29 C.F.R. Part 1910), HVAC contractors must maintain workplace safety standards, provide proper training for employees handling hazardous materials, and maintain documentation of safety practices. The Clean Air Act (42 U.S.C. § 7401 et seq.) establishes additional requirements for managing refrigerants and preventing environmental harm.
All HVAC businesses must obtain an EIN (Employer Identification Number) from the IRS (26 U.S.C. § 6109) if hiring employees. ADA compliance (Title II, 42 U.S.C. § 12101 et seq.) requires reasonable accommodations for employees and accessible business facilities. Workers' compensation insurance is federally mandated for any business with employees. Additionally, HVAC work in schools and federal buildings may require Davis-Bacon Act compliance (40 U.S.C. § 3141 et seq.) for prevailing wage adherence.
Local & County Requirements
Texas HVAC contractors must comply with multiple local requirements that vary significantly by city and county. Most municipalities require a local HVAC contractor permit or registration in addition to the state TACB license. Cities like Houston, Dallas, Austin, and San Antonio each maintain separate permitting systems through their building and development departments.
Zoning compliance is mandatory—you must verify that your HVAC business location complies with local zoning ordinances. Many cities restrict commercial HVAC operations in residential-only zones. Signage permits are often required if you display business signs larger than specified dimensions.
Building permits must be obtained before performing HVAC installation, replacement, or major repair work. Most jurisdictions require permits for any refrigerant system additions or upgrades. Mechanical inspections by local code officials are typical after installation, with inspectors verifying compliance with the International Mechanical Code or local amendments.
Fire safety permits may be required if your business operates from a commercial location with hazardous materials storage. Health department permits apply if you're performing work in commercial kitchens or medical facilities. In major cities like Houston, additional requirements include asbestos notifications if working in older buildings. Check with your city's building department and county health department for specific requirements, as regulations vary substantially across Texas's 254 counties.
Total Cost Breakdown
The first-year cost of becoming a licensed HVAC contractor in Texas includes multiple components:
EPA Section 608 Certification Exam: $150-$250. This is required before applying for your TACB license and is obtained through a third-party testing provider.
TACB License Application Fee: $370-$475 depending on your license class (Class A through Restricted). This covers the one-time application processing and background check.
Continuing Education (first cycle, if required): $200-$400. While not due immediately, most contractors must complete 8 hours of approved CE within the first renewal cycle, costing $25-$50 per course hour.
Business License/Permit: $100-$300, depending on your city and county. Most Texas municipalities require a local HVAC contractor permit or business license in addition to the state license.
Workers' Compensation Insurance: $1,200-$3,500 for the first year, varying by payroll and risk. Mandatory if you have employees.
General Liability Insurance: $500-$1,500 annually, typically required by customers and lenders.
If bonding is required (varies by municipality): $300-$800 annually.
Realistic total first-year range: $2,820-$6,825 including all licensing, permits, exams, and required insurance. Second and subsequent years cost approximately $1,800-$3,500 annually due to renewal fees and continuing education recurring costs.
Licence Renewal
HVAC contractor licenses in Texas renew every two years, with the renewal deadline typically falling on the second anniversary of your license issuance date. The TACB provides renewal notices 60 days before expiration. Renewal is completed entirely online through the TACB portal at https://www.tacb.texas.gov/.
Renewal fees range from $370 to $475 depending on your license class. All HVAC contractors must complete 8 hours of approved continuing education during each two-year renewal period. At least 4 hours must cover refrigerant recovery and handling (EPA Section 608-related), while the remaining 4 hours can cover general HVAC topics like electrical safety, building codes, or customer service.
You may renew online or by mail; online renewal is faster and recommended. If you miss the renewal deadline, your license will expire and you cannot legally perform HVAC work. Late renewal carries penalties and potential fines. You can apply for license reinstatement within two years of expiration, but work performed on an expired license violates state law. The TACB sends renewal reminders, but it is your responsibility to submit timely renewal paperwork.
Penalties for Operating Without a Licence
Operating without a valid HVAC contractor license in Texas is a serious violation with significant legal and financial consequences. Under Texas Occupations Code § 1302.409, performing HVAC work without a license is a Class B misdemeanor, carrying potential jail time up to 180 days and fines up to $2,000 per violation. If the violation involves handling refrigerants without EPA Section 608 certification, additional EPA penalties apply under 40 C.F.R. § 82.110, with fines up to $37,500 per violation.
The TACB actively enforces licensing requirements and investigates complaints from customers and competitors. Violations are typically discovered through customer complaints, building permit audits, or TACB field inspections. The TACB issues cease-and-desist orders requiring immediate termination of unlicensed HVAC work. Failure to comply with a cease-and-desist order results in additional criminal charges and enhanced penalties.
Operating unlicensed creates serious insurance complications. Homeowner and commercial property insurance policies typically exclude coverage for work performed by unlicensed contractors. If an accident or property damage occurs during unlicensed HVAC work, you face personal liability with no insurance protection. This can result in civil lawsuits seeking damages that you must pay personally. Additionally, customers who hired unlicensed contractors may pursue refunds and damages, leading to costly litigation. Repeat violations within five years can trigger felony charges under Texas Occupations Code § 1302.409, resulting in penalties up to $5,000 and up to one year in jail.

Frequently Asked Questions
Do I need an EPA Section 608 certification before applying for my Texas HVAC license?
Yes, EPA Section 608 certification is a prerequisite for all Texas HVAC contractor license types. You must pass the EPA Section 608 exam before submitting your TACB application. The exam is administered by EPA-approved testing providers and covers proper refrigerant handling, recovery, and recycling procedures. You can obtain the exam through companies like N.E. T., HVAC Pro Certification, or local community colleges offering the test. The exam costs $150-$250 and takes approximately 2-3 hours. You don't need to hold an active HVAC license to take the exam; this certification can be obtained first, then used as part of your TACB application. Once you pass and receive your certification card, submit the documentation with your TACB license application. Failing the exam requires waiting 30 days before retesting. Many contractors complete this certification within a few days of finding a test center.
What is the difference between Class A, B, C, and Restricted HVAC licenses in Texas?
Texas offers four HVAC contractor license classes with different experience requirements and scope limitations. Class A requires five years of experience as a licensed technician or apprentice and allows you to perform any HVAC work and supervise other contractors. Class B requires three years of HVAC experience or completion of an accredited HVAC program plus two years of experience; this class can perform most HVAC installations and repairs but may have restrictions on supervising others. Class C requires one year of HVAC experience and is restricted to basic HVAC work only; Class C contractors must work under the direct supervision of a Class A or B contractor. Restricted License is available for individuals without prior experience and allows only specific work tasks under direct supervision of a higher-class contractor. Most startup HVAC contractors choose Class B if they have relevant apprenticeship or educational background, or Class C if they are entry-level. Choose your class based on your actual experience to avoid delays; misrepresenting experience can result in license denial or revocation.
How long does the Texas HVAC contractor license application process take from start to finish?
The complete timeline from beginning to holding your Texas HVAC contractor license typically ranges from 4-12 weeks, depending on multiple factors. Step one (EPA 608 certification) can be completed in as little as one week if test centers are available in your area; some providers have same-day or next-day testing. Step two (submitting your TACB application) takes 1-2 days once you gather your documentation. Step three (TACB processing) takes 4-8 weeks on average, though the TACB may request additional documentation, extending this timeline by 2-4 weeks. If you need to gather work experience verification letters from former employers, that step can add 1-3 weeks if employers are slow to respond. Overall, plan for 6-12 weeks total, with 8 weeks being a typical average. To expedite the process, gather all documentation before applying: EPA 608 certification, work experience verification letters on employer letterhead with dates and descriptions, your high school diploma or GED, and proof of residency. Submitting a complete application reduces processing delays significantly.
Can I transfer my HVAC contractor license from another state to Texas?
Texas does not offer reciprocal licensing for HVAC contractors from other states. You must apply for a Texas HVAC contractor license through the standard application process, regardless of where you were previously licensed. However, your out-of-state experience may count toward Texas's experience requirements. If you hold an HVAC license in another state or have verifiable HVAC work experience elsewhere, submit documentation of that experience with your TACB application. The TACB will evaluate whether your experience meets Texas's requirements for your chosen license class. For example, five years of verified HVAC work experience from any state can qualify you for a Texas Class A license. You will still need EPA Section 608 certification (which is federally recognized, so if you already hold it, it applies to Texas). Complete the Texas application form, submit your out-of-state experience documentation, your EPA 608 certification, and pay the applicable Texas license fee. Processing typically takes 4-8 weeks. Having out-of-state experience may actually streamline your application if your documentation is thorough and well-organized.
What happens if I start performing HVAC work before my Texas license is approved?
Performing HVAC work in Texas without an active, approved HVAC contractor license is a Class B misdemeanor under Texas Occupations Code § 1302.409, with penalties including fines up to $2,000 and potential jail time up to 180 days per violation. If you handle refrigerants without EPA Section 608 certification during unlicensed work, additional EPA penalties apply, with fines up to $37,500 per offense. Starting work before approval creates multiple serious risks: customers may refuse to pay or demand refunds because your work is technically illegal; homeowner and commercial insurance will not cover unlicensed work, leaving you personally liable for any accidents or damage; the TACB receives complaints and will investigate, potentially leading to criminal charges even after you obtain your license; and you cannot legally collect payment for unlicensed work because the contract may be unenforceable. If your license is pending, the TACB office advises waiting for approval before accepting any HVAC jobs. You can perform apprenticeship-level work under a licensed contractor's supervision while waiting for your license, but you cannot independently contract or bill for HVAC services. Many contractors find temporary work or other employment until their license is approved rather than risk legal consequences.
Are there local permit requirements in addition to my Texas HVAC contractor license?
Yes, most Texas cities and counties require local HVAC permits or registrations separate from your state TACB license. This requirement varies significantly by municipality. Major cities like Houston, Dallas, Austin, and San Antonio each have their own permitting systems administered through city building and development departments. Some smaller cities may defer entirely to the state license, while others require local registration fees ranging from $50-$300 annually. To determine your local requirements, contact your city's building department or development services office before or immediately after obtaining your state license. You'll typically need to register your business with the city, provide proof of your state TACB license, and pay any applicable local permit fees. Additionally, individual HVAC jobs usually require mechanical permits before work begins, issued by the same local building department. Mechanical inspections verify that installations comply with local building codes and the International Mechanical Code. Failure to obtain local permits can result in citations, fines, and work orders requiring removal of non-permitted systems. Always check local requirements; assuming your state license covers all jurisdictions is a common compliance mistake.
