Thanks for the input guys. Greg, My Dealer was Randy. I can't remember his last name I just have his phone number saved as Randy Shaver. Easier to remember that way. Randy was actually the only one who would pick up my calls. I bought a refurbished unit and the fire box was corroded through when it arrived. I had phone conversations with I think her name was Melba, and she put me in touch with Ray. I don't like to complain but dealing with Ray was the worst customer service experiece I've ever had. It took me 9 more months for them to get another furnace to my house. So many unreturned calls, emails messages. I feel that even if my unit has a problem, I would have an easier time fixing it myself rather than try to deal with Ray again. Anyway I'm not here to complain about Shaver, I'm hoping for many years of great service with this unit!
