HVAC Excellence is a type of certification that was founded nearly 25 years ago to help raise competency of HVACR technicians. It is a certification that helps technicians, wholesalers, utilities, contractors, manufactures, and others prove HVACR knowledge and experience. HVAC Excellence offers 11 certifications exams that build on one another and can be combined to achieve various levels of certification such as “senior level” or “master” certification.

What is the difference between NATE and HVAC Excellence certifications?

Both NATE and HVAC Excellence certification are nationally recognized, offered through long-standing non-profit organizations, and highly-regarded in the industry. Technicians must pass a knowledge-based exam developed by experts in the HVACR industry to prove they are prepared to work as a technician and ready to handle various scenarios that may arise in order to earn NATE certification. Individuals with NATE certification must recertify every 5 years by retaking a specialty exam, earning 30 hours of NATE verified continuing education and a short specialty test, or completing 60 hours of NATE verified continuing education with no test. NATE certification is probably a little more well-known especially where private homeowners are concerned. HVAC Excellence certifications are thought to be more heavily based on experience that what you can learn in a book. Either certification, will put you a step ahead of your competition when applying for HVACR jobs and will show employers that you have what it takes to succeed on the job. With HVAC Excellence, individuals must also recertify every 5 years by taking an exam that covers new technologies.

What type of test is the NATE certification exam?

All NATE tests are multiple-choice, and will be given in a proctored test center.  You will be given 1.5 hours to answer 50 questions on the NATE Core Exam, and 2.5 hours to answer 100 questions when taking the NATE Air Conditioning Service specialty certification exam.

HVAC Excellence certification exams are multiple-choice, and must be completed with a proctor. You will first be required to pass the HVAC Excellence Core exam before moving on to the 100 question Air Conditioning specialty exam.

Why is certification important in this field?

Obtaining certification in this field shows that you are dedicated to your career. Many employers are looking to hire only certified professionals, and consumers are becoming more savvy and driven to find certified technicians for work in their homes and places of business. Earning your NATE or HVAC Excellence certification will show that you are motivated, knowledgeable, and experienced in HVACR. Certified professionals are often paid higher than technicians who have not achieved certification.

What is involved in the job of an HVACR technician?

An HVACR technician (sometimes referred to as an HVAC technician) is responsible for installing and repairing heating and air conditioning systems for private residences, businesses, public areas, etc. In this position, you will also work on refrigeration systems.
