The company said Monday the new name also covers its affiliates: Gateway Mechanical, Gateway Mechanical Fire Protection Inc. and Automation Solutions Group.

IFS has annual billings of more than $50 million, employs more than 220 people in St. Louis and mid-Missouri and serves more than 4,000 clients, the company said.

The rebranding is part of a move to better align the company name with IFS’ range of facility services including HVAC, plumbing, fire protection, building automation and building security systems.

“For the past 50 years, we’ve grown and diversified to serve all of our clients’ mechanical contracting and service needs,” CEO Bill Rundquist said in a statement “Our corporate name, Integrated Facility Services, better conveys that full range of services.”

IFS has its headquarters at 1055 Cassens Industrial Court, in Fenton, and an office in Columbia, Mo.
