The home I'm about to purchase has an Armstrong Ultra SX 80. Is their any website where I can find the furnaces AFUE rating? THe building was constructed in 1994, I'm assuming this is the original furnace.



thanks

The SX 80 was an 80 because it was just at 80 percent AFUE:

I found the same link but didn't understand what the "i" stood for.

I've got an energy efficient mortgage, would it benefit me to install a 95% efficiency furnace?

The table on that page is messed up with the columns shifted. Your model would have an efficiency of 80.3 for instance in the column that would normally be shifted over there. If you plan to live in the house for a decade, the higher efficiency furnace would use less gas to pay off the new furnace.

I was given the above furnace free, never been installed before. I know it's only an 80%, but that's alot better than the 30+ year old furnace my house currently has. I only have 2 problems: 1-there's no manual with the furnace. Does anyone know where I can get one? and 2-I'm no HVAC tech, but this furnace looks to me to be a downdraft model, maybe intended for a single story house, with the ductwork under the floor? My home is a 90yr old 2 story, with an updraft furnace in the basement. Is it worth the trouble to find a conversion kit for the Armstrong furnace? Or should I just sell it and put the money toward a newer furnace that's more in line with what I need?

Get a new furnace. a furnace that is built for downdraft doesn't convert unless it was a multi-position furnace in the first place.
