Hot Water & Steam Boilers
While R.F. MacDonald Co. has primarily competed in the industrial market, we have always offered our services to the Commercial Industry: corporate offices, apartment buildings, manufacturing facilities, lab facilities and schools. As of 2019, R.F. MacDonald Co. now sells the entire Commercial package too: boilers, pumps, tanks, heat exchangers and coil kits.
