Serving Phoenix, Arizona

Comfort Systems USA Southwest is a local company with national resources. Beginning in 1962 as Tri-City Mechanical, the company served the residential HVAC and plumbing market in the Phoenix and surrounding areas. It was truly a family business, where all members had a position at one time. As the business grew and moved to commercial, Tri-City Mechanical contributed to the building of churches, county administration buildings, prisons, hospitals and the first ever central cooling plant for downtown Phoenix.
