About American Boiler & Mechanical

A long and proud history of performance reliability earned us a reputation of being "Capable People You Can Count On!"

American Boiler & Mechanical was formed in 1973 by Harry Hemphill. When the company opened we were in a small shop in Fenton, MO with nothing more than a small office and a shop just big enough to park a utility truck. As our company has grown, we have moved to accomodate our needs; once to a larger facility in Fenton, then to the historical area of St. Louis known as "The Hill." Our facility houses several offices and a 25,000 square foot shop on a 2 acre lot.

In 1988 we began our expansion and opened a branch office in Kansas City, MO and in 1998 an office in Salina, KS. Between the three offices we are able to service several states.

We have grown over the years to maintain a fleet with over 85 service trucks, several containing mobile welders and all containing enough tools to perform any job from re-tubing a boiler to piping-in new equipment.

Our range of work has also expanded over the years going from strictly boiler repair and welding to a full range of mechanical services. We sell and install new equipment from boilers to heating and air conditioning systems, install process piping, perform plant maintenance, code welding, insulation and custom sheet metal work. Our specialty will always be boilers, but we are always eager to take on new challenges.
