Giving Back to the Community

We’re proud to support the next generation of skilled trades professionals! B.F. Mahn & Sons donated an HVAC system to Jefferson College so students can get hands-on experience working with real equipment as they learn the trade.

As a family-owned plumbing and HVAC company serving our community since 1868, we know how important hands-on training is. Thank you to Jefferson College for preparing students for careers in the trades. We’re excited to see this system put to work in the classroom! Supporting the trades.
