North American Technician Excellence, Inc.

NATE Certified technicians have passed one, or more, of the five North American Technician Excellence Tests that validates and verifies their knowledge of heating and/or cooling systems.

The NATE tests are more than just book learning, they are tests of applied knowledge. No one can guarantee how someone else will apply the knowledge they possess, but you can be assured that a technician who passes the NATE tests has the required knowledge to do the job.

NATE Certified Technicians:

  • Know how to do the job right the first time
  • Have 12.9% fewer callbacks
  • Achieve an average 55% higher rating in customer satisfaction surveys
  • Have passed a Department of Energy endorsed test

NATE Quality Circle

We are one of the few NATE Quality Circle Contractors in the area. Being a Quality Circle Contractor means that we commit to having 80% – 100% of our Technicians NATE Certified.

Having a NATE Certified Technician on staff is fine, but if that technician is not the one that shows up at your home or office, you don’t benefit. TriState Home Services currently employs 10 NATE Certified Technicians, including all of our Lead Technicians who perform system installations.
