Hi folks, I a few days or as soon as my income tax gets here I'm going to replace the furnace in my home. So, I wonder if this would be the best forum to discuss this subject. I will be asking for advise, best type of unit, price, how I should go about getting a price (apples for apples) so that everyone is on the same page ect. I have a whirlpool that's now on 30yrs old, still runs good. But, I'm concern that the heat chamber may in poor shape and I don't need carbon dioxide coming the the living area. Thanks for any advise you folks may have. Billy J.
