What affects the price

When you look at the cost of a new HVAC system, several variables come into play. The size of your home and the necessary cooling or heating 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 components to support a modern system. Labor requirements, including accessibility and permit fees, further influence the final number.
