About Williamson-Thermoflo

Williamson and Thermoflo are two highly recognized brand names that formed a partnership in December, 1999 as the new Williamson-Thermoflo Company.  While these two veteran names enjoy a proud and lengthy history, the partnership begins a new and exciting chapter in the growth of the company. 
Established in 1890, Williamson quickly developed into a highly regarded manufacturer of heating and cooling equipment. 

Developed in 1946, the Thermoflo line of residential furnaces quickly established itself as a provider of high quality and durable equipment.  Since its inception, the Thermoflo line has met with continuous growth and made several additions to the Thermoflo product line. 

The Williamson-Thermoflo company offers products and services in the tradition and quality customers have come to expect. Williamson-Thermoflo, a company on the move hopes to enhance the strong foundation established by these two historically strong brand names by blending their best qualities into one outstanding company.
