I use a frigidaire in the window.

Carrier and Trane make good stuff. My house has a 1 year old 98% efficiency "Nordyne" or whatever furnace.....it will be interesting to see how it holds up....it came with the house, otherwise I'd have put in a carrier/trane. Maybe it will prove me wrong.

My parents have a 26 year old trane furnace, and it has never failed. In my whole life it needed one thing repaired, the pilot light fuel pipe. Thats it. Still works fine, but they are going to replace it with a high efficiency model in the near future. 65% is a bit expensive to run.
