John Miller
John Miller – Owner/President

John started in the HVAC industry in 1986 and quickly discovered his passion for serving others (both clients and staff). John’s intimate knowledge of the valley’s climate and demands is married perfectly with his years as a master technician. His reputation is well established in the HVAC community and the testimonials from clients over the years have resulted in an almost exclusively referral-based company.
