Brand Histories

An ever-changing and intertwined index of company mergers, consolidations, and defunct brands.

The following are names and compiled histories of  numerous HVAC related companies and brands. We have accumulated this data from multiple sources and years of research. The information is reasonably believed to be accurate to the best of our abilities; however, if you find that we have erred or discovered new information, we would love for you to let us know!

The information that we have compiled may help to determine the era of manufacture for some systems, especially those brand names that are no longer in business (defunct),  obsolete, difficult or impossible to decode the serial numbers, or have been adopted by other manufacturers.
