CNewhouse Posted August 18, 2021 Report Share Posted August 18, 2021 According to building-center.org, this Trane high-efficiency furnace was manufacture in 1986. Is that accurate? I can't remember ever seeing a 90%+ efficient furnace manufactured prior to 1990. Many thanks. Quote Link to comment Share on other sites More sharing options...
CNewhouse Posted August 19, 2021 Author Report Share Posted August 19, 2021 Apparently, building-center.org has S and Z in the wrong position in their key. It's a 2001. Nothing to see here. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted August 21, 2021 Report Share Posted August 21, 2021 You listened to your instinct. That's good. Quote Link to comment Share on other sites More sharing options...
Mike Lamb Posted August 21, 2021 Report Share Posted August 21, 2021 You probably know that there should be an ANSI date somewhere on the data plate. Add a couple years to that and you'll have a good idea of the manufactured date. Quote Link to comment Share on other sites More sharing options...
