HVAC Certification & Why It's Important

Being a certified HVAC technician is important. You’ll be working on important, expensive, and sometimes dangerous equipment. People will want to know you've been trained to do it right. Certification helps prove you can.

HVAC Licensing

To prove you are a trained and capable HVAC technician, you must first be licensed. Each state has its own set of licensing regulations, and you can check with your state’s licensing department to find out what is required. A career counselor at the school of your choosing can help guide you. 

NATE Certification

The North American Technician Excellence certification is highly regarded as a benchmark for recognized and respected HVAC technicians. You must pass this knowledge-based exam in order to become certified, but this certification is voluntary. This exam is also used for specialized areas such as air conditioning, air distribution, and gas furnaces. To have a NATE certification means you are highly knowledgeable and qualified to do your job.

EPA 608 Certification

You must be EPA 608 certified to work with any type of refrigerant containers. So, to be able to purchase refrigerants—or even work on systems or containers that store refrigerants—you must be certified. There are three levels to the EPA 608 certification:

  • EPA 608 Type I allows an HVAC tech to handle small appliances that contain less than 5 pounds of refrigerants (like a refrigerator, vending machine, or residential air conditioner).
  • EPA 608 Type II will allow the HVAC professional to service and dispose of  equipment with high-pressure refrigerants (such as a large air conditioner, heat pumps, or a commercial refrigerator).
  • EPA 608 Type III allows the handling of low-pressure refrigerants (like a chiller).

To earn the professional level, you must have a minimum of two years in the field and pass an exam specific to specialties such as residential air conditioning.
