The Integrated Facility Services’ team of talented engineers and skilled technicians design, build and manage sustainable HVAC and facility solutions. Our goal is to ensure occupant comfort and safety, optimize systems performance, save energy, and reduce operational costs over the lifetime of a building.

At IFS, more than 200 professional and trade employees proudly partner with client facility teams in the Midwest and around the country. We’re ready to partner with you.

For the past 50 years, we have provided a wide range of mechanical engineering and building services including HVAC, plumbing, building automation controls, fire protection, 24-hour service and more, but under several different company names.

We’ve rebranded as Integrated Facility Services to let everyone know about the full range of integrated services we provide to seamlessly build, operate, manage and service our clients’ mechanical and building automation systems in St. Louis and across Mid-Missouri.
