BOSTON (WHDH) - Many Massachusetts families use propane to heat their homes, but there were delivery issues this winter. “We have three furnaces, heat flooring, all of our hot water heaters, our appliances, literally the entire house,” explained Billerica resident Michele Aquaro. Propane powers just about everything in her home, but she’s never had to worry about it. Deliveries from Superior Plus Propane kept her Billerica home running smoothly — until this winter.
