Hi,I am looking to buy a furnce.Where can I buy a furnace directly from the manufacturer.Thanks

Unless you are a dealer doing this for a living, I doubt you will find one this way

Ebay

But why would you want to? Are you a heating tech, can you install your own, do you not want any warranty on it, since unless you buy it from a dealer it would not be included normally

You can find plenty on eBay,, but beware if not a qualified installer,, you probably won`t get a warranty,, sometimes you buying a pig in a poke
