What affects the price

Installing a new HVAC system involves several variables that shift the final total. The square footage of your home and the necessary cooling capacity—measured in tons—are the biggest factors. 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.
