I am leaning toward Amana AMV9 furnace with ASX14 AC because of the combination of price and warranty. My other option is a Lennox G61V (my favorite contractor sells these two brands.
There is a website which seems to be supported by carrier http://220.127.116.11/cac_sound_comp...arrier_web.swf
The AMV9 sounds like a jet engine and I find this hard to believe. Can anyone comment please?
