Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

For aspiring heating, ventilation, and air conditioning (HVAC) specialists, pursuing certification can be a way to show one’s competencies to prospective employers or clients. These credentials can demonstrate a wide range of skills in the field such as: installing, repairing, and maintaining HVAC units in residential or commercial spaces; analyzing air quality, humidity levels, and temperature control mechanisms; understanding the fundamentals of heating and refrigeration systems.

Some job-ready HVAC programs include the certification process as part of their training program such as the one at North American Training Center. That said, there is a wide array of agencies offering HVAC certifications for those looking to enhance their credentials. The North American Technician Excellence (NATE) hosts the “industry competency exam” and provides a number of HVAC-R specialty certifications such as air distribution (AD), HVAC efficiency analyst (senior level), and HVAC performance verifier. HVAC Excellence not only provides program accreditation, but has employment-ready certification exams for air conditioning, light commercial air conditioning, and basic refrigeration and charging procedures. The Refrigeration Service Engineers Society (RSES) has a partnership with NATE and provides additional certification exams including EPA section 608, commercial air conditioning, commercial refrigeration, heating, and HVAC-R electrical.

Enjoy the app and pass your HVAC, NATE, HVAC-R, RSES, EPA, Heating, ventilation, air conditioning exam effortlessly!

Repeats questions, multiple times

I have passed every state exam, so I really didn’t need this, but I was curious. I found it a bit irritating, when I got the same 3 questions 3 or 4 times in a row

Developer Response ,

Hi Goriotoo,
To master a question, you need to answer it correctly 2 times. By doing this, the app helps our users to remember every question. You can choose the simple mode in the top right menu to disable it.
Let us know if you have more question by sending us an email right in the app.
Thank you
