Our company has actually been using the Fan Handler for over 20 years, dating back to the belt drive units. Bob Bills, from our company (Henson Robinson at that time) purchased units from you back then. Bob Bills retired from an engineering job with the state and 2 years ago he ask me to install a new heating system. I recommended we install the Fan Handler that he used to install years before. I installed it and since he was an engineer, I had to go back and put your "Dial-A-Speed" remote speed selector. What engineer can be satisfied with a product out of the box, right?
Thanks for a great product.
