Early 90's hi-efficiency Carrier Furnace

[Matt Fellman]

I know the problems with the Lennox Pulse's are well documented. The unit I saw today was from roughly the same time period and was probably pretty cutting edge technology for its day.

I couldn't find anything on the net about this particular unit. Does this type/brand ring a bell to anyone?

Carrier Model# 399aaz036060 (not sure if those are O's or zero's - I ran it both ways and didn't find anything)

66K Btu, 1991 manf. date.

There was a recent legal action involving some secondary heat exchangers in Carrier/Bryany/Payne equipment made in that time frame.
