NATE stands for North American Technician Excellence and is an independent organization that certifies installation or service technicians with a knowledge-based test. A recent survey says that 87% of air conditioning and heating consumers prefer certified technicians. Organizations that are part of the NATE coalition include the U.S. Environmental Protection Agency and American Society of Heating, Refrigeration and Air-Conditioning Engineers.
To become certified installation and/or service technicians, these technicians must pass both core and specialty parts of either an installation or service test with a score of 70 or better. Specialties include heat pump, air conditioning, air distribution, oil heat and gas heat.
The NATE test is not easy, and not all technicians pass it the first time. NATE certification verifies that the technicians who pass are the best in the trade when it comes to knowledge and experience installing or servicing your home heating or cooling system.
