Welcome to Smith-Boughan Mechanical Services

Smith-Boughan has roots deeply entrenched in Allen County, Ohio. Established through the merger of two well known family businesses, Terry P. Smith & Sons and Boughan Brothers, Smith-Boughan has been continuously serving West Central Ohio since 1927.

Since its founding, Smith-Boughan’s purpose is to develop long-term quality relationships with our clients and employees. Today that emphasis continues with over 70% of our work coming from repeat clients, performed by many second and even third generation employees. We look forward to the continued success but most importantly the opportunity to earn your business.

I have learned from experience that you get what you pay for and we have had some bad experiences with other mechanical/plumbing contractors on bid jobs that we ended up calling Smith-Boughan as consultants or to fix problems that the low bid” contractors messed up.
