I am hoping you all can give me some advice. I am in need of a new heating and cooling system. I currently have a 20+ year horizontal Trane furnace and an 11 year old Lennox air conditioner. The furnace died at the end of the winter and the A/C has now given up the ghost. Currently the furnace is in a moist crawl space. I have had 4 companies out for quotes--Lennox, Bryant, American Standard and Century/ Goodman. Most have recommended that I move the furnace up into the garage area which there is room for though it will mean breaking through the concrete floor and then the cement block wall into the crawl space. Unfortunately cost is a major factor. That being the case I have had to eliminate the Lennox and American Standar Dealers. That leaves me with the Bryant or thethe Century/Goodman set up. The house is approx 2000 sq ft with fairly good insulation - new windows & doors as well. I live in Indiana where we have some cold winters. The Byrant has quoted a 80,000 BTU 93%(?) furnance and Century is quoting a 70,000 BTU 92%. The A/C quote is pretty much the same with 2.5 - 3 T 13 SEER units. The bottom line is I have never heard of Century furnances and I have seen the mixed report on the Goodman units. Are they comparable enough that I am comparing apples to apples??
