What is the difference between HVAC licenses and certifications?

HVAC certifications and licenses are two different qualifications for working in the HVAC industry. A certification is a specialized and voluntary qualification that proves the knowledge and skills of an individual HVAC technician in a specific area, such as installation or repair. It is awarded by training organizations, manufacturers, trade unions, professional associations, and other educational institutions.

On the other hand, licensing is a legal requirement set by each state to protect citizens from untrained and unqualified HVAC technicians. To obtain a license, one must generally have several years of hands-on experience in the field, along with technical education or apprenticeship programs.

Additionally, most states require applicants to pass an exam demonstrating their competence in the trade before they can obtain a license to practice. As such, having both certifications and licenses is essential for anyone who wants to work as an HVAC technician.

What bonds and insurance coverage does an HVAC contractor need?

HVAC contractors require a state license from their state in order to operate a business. This license is necessary to ensure that the contractor has the skills and knowledge required to safely and effectively install, maintain and repair HVAC systems.

In addition to the license, HVAC contractors also need general liability insurance coverage to protect themselves from financial losses due to property damage or injury caused by their work on HVAC systems. This insurance can help cover costs associated with medical bills, legal fees, or other expenses related to claims against the contractor.

sBonding is an additional type of protection for both the contractor and customers as it helps guarantee that any services provided will be completed as promised. So, when looking for an HVAC contractor, make sure they have a valid state license and are properly bonded and insured.
