So my condo's 25+ year old gas furnace decided to die this past week. I have had two different companies out to give me estimates and such. Both agree that an 80%, 2-stage gas furnace is what we need and a new condenser is in our very near future. One company deals exclusively in Goodman products, the other, a larger company, works with Carrier, Trane, Lennox, and others. When reading reviews, it seems most people have either great or horrible things to say about each brand, nothing in between. My question is does anyone have any preferences and/or advice on products? We don't plan on being here more than 5 more years, if we can help it, so we want something that will work for us now and get us through a home inspection down the line.
