We are proud to have served the St. Louis area's heating and air-conditioning needs since 1966. From office buildings, industrial plants, hotels and motels to apartments and residential homes, the list of installations successfully completed by the IFS family of companies goes on and on. Our objective is always to give our clients the most efficient and dependable systems at the greatest possible savings, through our three outstanding companies:

Air Masters Corporation
Gateway Mechanical
and
Automation Solutions Group

There is another consideration that we keep in mind. In this fast-moving world, change is inevitable, and the needs of tomorrow must be anticipated in the products and the systems we provide today. That's why IFS installations are designed with the features that will assure our clients that future changes like expansion or renovation will not render their mechanical and control systems obsolete.
