License Requirements for HVAC Contractors


HVAC contractors install and repair heating systems, air conditioners and refrigeration systems. They either work for businesses or homeowners. Some HVAC contractors are specialized to do installation, maintenance or repair, although some will do all of the above. In order to become a HVAC contractor, one must receive on-the-job or postsecondary training, including licensing. Licensing requirements vary by state, but all require candidates to take a test in order to pass.

Ohio Requirements

  • The Examining Board of Ohio will grant a license to HVAC contractors in electrical, plumbing, refrigeration and hydronics. In order to receive a license, candidates must pass the examination that the Examination Board offers. Once a candidate receives his license, he must maintain his license by taking continuing education units. They can use these continuing education units to renew their licenses annually. Candidates must also work as a licensed HVAC contractor in the state of Ohio.

Utah Requirements

  • Candidates must have at least four years of experience under the supervision of a licensed HVAC contractor. They may receive this experience through postsecondary training, on-the-job training or through apprentice programs. The examination will cover the fabrication and installation of warm air heating systems, cool air systems and complete ventilating systems. There is a $110 nonrefundable deposit in order to take the examination. Utah has no continuing education requirements at the time, according to the Contractor Licensing website.

Texas Requirements

  • The state of Texas offers licenses to HVAC contractors who install fire sprinkling systems, plumbing systems and electrical systems. In order to seek licensing, candidates must submit an application to the Texas Department of Licensing and Regulation. There are two types of licenses: Class A and Class B licenses. The Class A license allows HVAC contractors to work on any HVAC equipment while the Class B allows HVAC contractors to work on cooling and heating systems. For either of these licenses, candidates must pass the examination. In order to apply for the licenses, candidates must have three years of work experience in the five years that they earned their degrees. Those who have a HVAC license in Georgia or South Carolina can receive a license in Texas. The application fee is $50, the license fee is $115, and candidates must renew it every year. The renewal fee is $65.
