A: One of the biggest problems in the heating and air conditioning industry is the lack of trained professional technicians. Poorly trained service technicians and shoddy installation are the two primary reasons that consumers need to keep having a repairman come to their home. North American Technician Excellence, Inc. (N.A.T.E.) is the leading independent certification body for technicians in the heating, ventilation and air-conditioning (HVAC) industry. They establish the industry’s standards for excellence and administer the training, testing and validation procedures for meeting those standards. Not only are Horizon’s service and installation technicians N.A.T.E. certified, we are also the only HVAC company to have its own N.A.T.E.-certified in-house trainer and training facility. That means that our skills, knowledge and commitment to service are growing continuously.
