A Rich History of Home Comfort

The story starts in 1885 with Thomas J. Fannon delivering wood and coal. As times changed, so did the business. They moved into coal delivery with trucks, then adapted to heating oil in the 1940s. When natural gas lines and air conditioning arrived, Fannon's was there to install and service the new equipment. Today, they bridge centuries of expertise. Their showroom has technology from three different eras, and their staff can work on a cranky old steam boiler or design a brand-new, high-efficiency heat pump system. This deep history is a unique asset.
