About Us

United Air Temp is a full-service HVAC, plumbing, and electrical company with a Jessup, Maryland branch serving the Baltimore-Washington region. 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. The Jessup operation supports customers throughout Central Maryland and the surrounding corridor, while the company’s broader regional footprint extends through Maryland, Washington, D.C., Virginia, and other southeastern markets. For commercial and facility customers, the company’s combination of HVAC, plumbing, electrical, preventive maintenance, and emergency service capabilities positions United Air Temp as a long-term building-systems partner rather than a one-off repair provider.
