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."

American Boiler & Mechanical has multiple used boiler systems and HVAC fored air systems available to purchase. System details and photos are found on the below pages. If you are interested in learning more about a system listed, please call 314-865-3000 or contact us online.

We are with you every step of the way from start to operational implementation and follow-up. We will assist in the initial steps of planning and designing your boiler system and also provide 24/7 support if you need any boiler repairs or maintenance. American Boiler & Mechanical also has a range of rental boilers that are ready for immediate delivery. These rental boilers range from 5 boiler horsepower to 500 boiler horsepower. Most of these units are trailer mounted and can be rapidly deployed in emergency situations too!

Below are several services we offer. If you are interested in other boiler, HVAC, plant maintenance, or service contract services not listed here, please contact us directly.
