3.5 Ton - 80,000 BTU - 80% AFUE - Horizontal AC & Furnace Systems
52 matched systems, cheapest first. A 3.5 Ton system usually suits a home of roughly 1,750 to 2,100 square feet, paired here with a 80,000 BTU 80% AFUE horizontal furnace. This is a standard efficiency furnace that vents through a metal flue. Every system ships with the outdoor unit and the matching indoor side together.
10 of these are marked "Northern states only." Federal efficiency rules let lower-SEER2 air conditioners be installed only in the northern half of the country. If you live in the South or Southwest, pick one without the tag, or call (877) 843-4822 and we will point you to the right one.
