The company traces its history to 1931 and has grown from a small local operation into a multi-state organization with more than 30 branch offices and over 300 technicians and support staff. United Air Temp provides heating and cooling installation, repair, and maintenance, plumbing services, selected electrical services, indoor air quality solutions, and preventive maintenance programs, with 24/7 emergency support available.
