Weil-McLain Boilers
Weil-McLain manufactures cast-iron and condensing boilers for several fuels and applications. A.J. LeBlanc Heating evaluates the home's heat loss, radiation, zones, water temperatures, venting, and fuel before recommending a model. We also maintain and repair existing Weil-McLain equipment throughout Southern NH.
Our technicians are factory-trained and certified on Carlin, Beckett, and Riello oil burners. We match the burner to the equipment and set up combustion for safe, proper operation within the manufacturer's specifications.
