Discover The Importance Of NATE HVAC Certification
NATE certification (North American Technician Excellence) is a professional credential that validates a technician’s knowledge of heating, ventilation, air conditioning and refrigeration (HVACR) systems. For homeowners, hiring a NATE-certified technician means working with a professional who has demonstrated technical knowledge through industry-developed certification exams.
Carrier places a strong emphasis on NATE certification. To achieve and maintain Carrier Factory Authorized Dealer status, at least 50% of a dealer’s technicians must hold NATE certification. This requirement gives homeowners an additional credential to look for when choosing an HVAC professional.

What is NATE HVAC Certification?
NATE certification is a nationally recognized certification program for heating, ventilation, air conditioning and refrigeration (HVACR) technicians. It serves as independent proof that a technician has demonstrated technical knowledge in specific areas of HVACR, from air distribution to heat pumps.
Unlike general trade licenses, NATE certification requires passing specialized exams through one of NATE's certification pathways. With the Traditional Pathway, technicians take a Core exam and a Specialty exam. NATE also offers the Certified HVAC Professional (CHP-5) pathway, which consists of five exams covering HVAC Fundamentals, Electrical and Controls, Comfort and Airflow, Installation, and Service.
Because NATE certifications generally must be renewed every two years, technicians can maintain their credentials by completing 16 continuing education hours during the two-year certification period or retaking the applicable specialty exam.
Why Choose A NATE Certified Technician?
Choosing a NATE-certified technician can help homeowners identify HVAC professionals who have demonstrated knowledge through a recognized certification program. These professionals have proven their competency through testing, although certification alone does not guarantee the quality of a particular installation, repair or service visit.
1. Expertise and Precision
NATE-certified technicians have passed certification exams designed to test technical knowledge in specific HVACR areas. This expertise can be particularly valuable when diagnosing complex issues or performing HVAC installation or HVAC repair.
Brad Gooch, HVAC manager of Lawson Air Conditioning and Plumbing in Gainesville, GA explains the importance of working with a NATE-certified HVAC technician.
“If you buy a brand-new car, are you going to take it to just any mechanic to have it serviced?” Gooch said. “Most people would take it to a qualified technician who has the proper training and understands that vehicle. HVAC systems are no different."
2. Quality Assurance and Standards
Carrier recommends working with qualified HVAC professionals who understand proper equipment sizing, installation and service. NATE certification provides one way for technicians to demonstrate their technical knowledge in specific areas of HVACR. This attention to detail maximizes the lifespan of your HVAC unit and ensures it operates safely and quietly.
“NATE certification provides valuable training and testing for technicians at different stages of their career," Gooch said. "It's a good refresher for experienced technicians and can help newer technicians build their technical knowledge and skills."
Proper installation is especially important because ENERGY STAR states that improper HVAC installation can reduce system efficiency by up to 30%. 1
3. Maximized Energy Efficiency
NATE certification does not itself guarantee a specific level of energy efficiency, but technicians with training and certification in HVAC installation and service can help address factors that affect system performance. Proper sizing, airflow, refrigerant charge and ductwork are all important parts of a quality HVAC installation.
According to the U.S. Department of Energy, studies estimate that more than 65% of residential HVAC systems have been improperly installed 1, resulting in equipment consuming approximately 20%–30% more energy than necessary1.

4. Commitment to Ongoing Education
The HVAC industry changes rapidly with the introduction of smart home integrations and new equipment and refrigerant technologies. NATE requires certified technicians who recertify through continuing education to complete 16 CEHs every two years.
“It goes beyond just understanding the equipment," Goch said. "Proper HVAC service also involves communicating with homeowners, explaining what you're doing and treating the customer's home with respect. When you have a NATE-certified technician working in your home, it gives you added peace of mind that you're working with someone who has demonstrated knowledge of HVAC systems and has taken the time to develop their professional skills.”
