Today, more than ever, technicians need
extensive knowledge and a wide skill-base
to successfully install and service
sophisticated and computerized heating and
cooling systems.
Proper education and training are crucial.

How can you be certain the
technician working on your home is
qualified?
What exactly is NATE?
NATE is an acronym for North American
Technician Excellence, Inc., an independent,
third-party certification testing organization.  
NATE tests technicians’ knowledge of heating,
air distribution, and cooling for HVACR
residential and light commercial applications.  
Technicians passing the NATE test earn
certification. The NATE test is a voluntary test
of applied knowledge, and open to everyone
practicing in the HVACR field.  Third-party
validation means a disinterested entity (NATE)
evaluates a technician’s knowledge –
determining legitatemely if a technician is
qualified to be working in consumer’s homes.
Why does NATE exist?
 What does this mean for you?
● Manufacturers and wholesalers wanted to
decrease the amount of units which were being
returned as “defective”, but, were actually
installation errors caused by unskilled
technicians.

● Consumers needed a way to identify a
knowledgeable technician from one who was not
– in effect, anyone can say they know heating
and cooling, but, those holding independent
NATE certification can prove it.  
By hiring only a NATE certified technician you can be
certain the technician working on your home is
qualified and knows what he is doing.  Sure, there are
technicians out there who are not certified, yet, still
have the skill necessary to work on your home, but,
how do you know if they do or not?  NATE certified
technicians prove to you they are qualified before
they start working on your home.  By hiring a
NATE certified technician you know what you are
getting for upfront – a technician you can trust your
home with.
