If you get a new try to get a Trane or American Standard. They are the quietest. Go for an 80% effencient with a variable speed fan. It's a little more expensive but will save you a lot of money on running it. I used to sell furnaces in a previous lifetime and when we needed a new one, I wish I ahd got the ones I used to sell. I have a Lennox and it is VERY LOUD!!!!
