Williamson-Thermoflo is behind some of the most reliable, well-respected brands of heating and cooling systems in the industry: Williamson® and Thermoflo®.
The Thermoflo and Williamson brands are very similar, and are the result of a number of mergers and acquisitions that took place in the history of Williamson-Thermoflo. Today, both brands offer reliable, long-lasting oil- and gas-fired cast iron boilers, furnaces, air handlers, air conditioners and indirect-fired water heaters.
While the choice of brand is usually a matter of personal preference or brand loyalty, all Thermoflo and Williamson products offer rugged construction and reliable performance and are backed by a solid warranty.
