*NATE encourages the employment of NATE certified technicians for superior installation and maintenance or service of heating, ventilation, air conditioning or refrigeration systems. NATE certified technicians have proven their knowledge in the HVACR industry by passing specialized NATE certification tests; however, NATE does not directly supervise or employ technicians, and does not endorse or guarantee their work or performance.  As a result, NATE disclaims any liability related to services performed by an individual technician or recommended employer.
