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.
About this service
Central AC installation involves connecting a high-efficiency condenser outside to your existing ductwork to cool the entire house. The final price depends on the size of your home, whether your current ducts need modifications, and the SEER rating of the unit you choose.
