Hello,

Thanks to everyone who helped me yesterday with my Tempstar furnaces.

House Built in 1991.
* 1st Floor + Basement: 1991 TEMPSTAR Gas Furnace 120K BTU
* 2nd Floor: 1991 TEMPSTAR Gas Furnace 100K BTU

Furnace NUGI100DH03, Serial L904166400

The Questions are (I could not get this from Tempstar website http://www.tempstar.com)

1. Heat Exchanger Warrnaty: is it 10 yr or 20 yr wanrraty?

2. Efficiency of this furnace (with nat. gas price going up I am worried), is it 70%, 75% or 80%?

Does anyone know? TIA.
