You also have to consider the efficiency rating of the unit, the complexity of your existing ductwork, and whether you need to upgrade electrical or gas lines to accommodate the new equipment. Choosing between a standard single-stage unit or a high-efficiency multi-stage system changes the upfront investment significantly. Exact pricing confirmed free on the call.
