Bryant has been around since 1904. Charles Bryant is the developer of the modern day furnace and offered 80% efficiency on their furnaces in 1919. They partnered with Payne in 1949 and in the mid 1950s were bought by Carrier. In the 1980s Bryant was one of the first pioneers of the 90% furnace. That is part of why Prosper's Finest A/C and Heat is proud to be a Bryant Factory Authorized Dealer!
