"We purchased a Central Boiler unit from John in 2007. Before, we were paying close to $500 a month for heating oil in the winter. Now after 4 seasons, our unit is just about paid off in the money we save buying and using wood as an alternative fuel source. John and his crew were professional (hence the name) and polite in installing the unit and explaining the details of the workings of it."
