Do you know your state’s HVAC license requirements?HVAC licenses can vary wildly from state to state, with many states having different rules and procedures. Some states may reciprocate licenses from other specific states, meanwhile, other states may not require a license at all— or they may require a license locally.To ease the confusion, we’ve compiled a full list of HVAC license requirements by state.

Why Become HVAC Certified

Anytime the public’s lives or livelihoods depend on quality service delivery, the role of independent authorities in a labor market balances the interests of everyone. Skilled professions benefit from certifications, in general, because certification and licensing requirements increase consumer trust and protect them from predatory or unsavory operators.Some states may not have requirements for HVAC licenses.

For example, Colorado doesn’t require a state license although it’s possible to become certified through a recognized industry or trade organization.It’s generally a good idea to obtain a professional certification even if your state doesn’t require it. Becoming certified gives HVAC businesses a number of competitive advantages, like helping increase sales. When potential clients are choosing a company, certifications can assure them your company has the most qualified technicians to complete a job. This can give clients the final push they need to choose you over a competitor.

Additional HVAC Certification Requirements

In addition to state requirements, the EPA requires all HVAC technicians to take an exam for handling refrigerant. The test covers topics like compliance and leak repair requirements in order to protect the environment. Technicians will then receive a Section 608 Technician Certification that lasts for life and doesn’t require renewal.For HVAC professionals who wish to work in commercial or industrial settings, one interesting certification is the LEED certification, offered by the US Green Building Council. USGBC offers two levels of individual LEED certifications.

Drawbacks of Not Having an HVAC Certification

HVAC contractors who operate without a license can find themselves fined, embroiled in legal battles, or even subject to lawsuits should something on a job go wrong. GCs who hire unlicensed contractors as subs risk losing their own license. Even homeowners themselves face fines for hiring unlicensed HVAC contractors if that contractor is performing work that requires a permit to be pulled.It is important to understand all of the laws and regulations pertaining to licensing and certification for your areas of service operations.

How Much Does an HVAC Certification Cost?

The cost of obtaining your HVAC license or certification can range depending on the state or issuing body. In most cases, the total cost will range from the low hundreds of dollars to potentially thousands of dollars over time. Typical costs may include course registration fees, the cost of materials or coursework, examination fees, renewal fees, and even reinstatement fees should your certification lapse or expire.
