Choosing the Right Licensed HVAC Contractor in Connecticut Could Save You Thousands in Costly Repairs and Ensure Your Family’s Safety

When your heating or cooling system fails during Connecticut’s extreme weather, finding a qualified contractor becomes urgent. But rushing into a decision without verifying proper licensing and credentials can lead to expensive mistakes, safety hazards, and legal complications. Understanding Connecticut’s 2024 HVAC licensing requirements will help you make an informed choice and protect your investment.

Connecticut’s Strict HVAC Licensing Requirements

Connecticut requires all HVAC professionals to be licensed before performing ANY kind of HVAC/R work, making it one of the most stringent states for contractor oversight. The Connecticut Department of Consumer Protection (DCP) based in Hartford issues all professional licenses and oversees the Heating, Piping, Cooling, and Sheet Metal Examining Board.

Connecticut has 20 specific licenses for HVAC professionals, depending on the exact type of work. The most common contractor licenses include:

  • S-1 Unlimited Heating, Piping, and Cooling Contractor – allows all heating, piping and cooling work as defined in section 20-330 of the Connecticut General Statutes
  • D-1 Limited Warm Air, Air Conditioning and Refrigeration Contractor – covers installation, repair, replacement, maintenance or alteration of any warm air, air conditioning and refrigeration system
  • G-1 Limited Heating, Piping, and Cooling Contractor – covers gas piping systems and approved gas appliances for LP gas and natural gas

Education and Experience Requirements

Connecticut’s licensing process ensures contractors have proper training. To be eligible for an HVAC license in Connecticut, you must be at least 18 years old, have a high school diploma or GED, and have at least two years of experience working in the HVAC industry. Additionally, Connecticut requires HVAC contractors to complete an approved education program in HVAC that includes at least 600 hours of instruction and covers topics such as refrigeration, heating, ventilation, air conditioning, and electrical systems.

The path to becoming a licensed contractor follows a structured progression: Connecticut requires that the HVAC contractor applicant or someone they employ carries a journeyman HVAC license for at least two years before applying for a contractor license.

Exam Requirements and Fees

HVAC contractors in Connecticut must pass both a trade exam and a business and law exam. The exam may last anywhere from 2 to 3 hours and contain up to 80 multiple choice questions, with all exams requiring a minimum score of 70% to pass.

For contractor licenses you must take both the appropriate trade exam and the Connecticut Business and Law Examination, with each portion costing $65 for a total of $130. The application fee for contractor is $150.00 (Non-Refundable).

Insurance and Bonding Requirements

Licensed contractors must carry proper insurance protection. You must provide proof of liability insurance with minimum coverage amounts of $500,000 per occurrence and $1,000,000 in aggregate. Connecticut requires all businesses with at least one employee to carry workers’ compensation insurance.

Some localities in Connecticut may require contractors to post a bond as a part of the licensing process, which serves as a financial guarantee for the completion of the project and adherence to local building codes and regulations.

How to Verify Your Contractor’s License

Before hiring any HVAC contractor, verify their credentials through official channels. Be sure to verify licenses and registrations before you hire anyone by visiting https://www.elicense.ct.gov. The State Department of Consumer Protection has a website where you may check a registration or license, and also inquire about complaint information against the contractor, they may also be reached at 860-713-6000 or 1-800-842-2649.

When evaluating contractors, request formal agreements, carefully study them before signing, and ask for references to confirm that they are appropriately insured and bonded. You may also verify their online reputation.

License Renewal and Ongoing Requirements

All license types must be renewed annually, with all heating, cooling and sheet metal work licenses expiring annually on Aug. 31. Renewal fees are $150 for contractors and $120 for journeypersons. All licenses must be renewed annually, which can be done through an online portal on the Department of Consumer Protection website.

Red Flags to Avoid

Be cautious of contractors who cannot provide proper documentation.

Additional warning signs include contractors who demand large upfront payments, lack proper insurance documentation, or cannot provide verifiable references.
