The answer to the price of a new HVAC system is that it can vary significantly depending on several factors. Generally, a new HVAC system for a typical home can range from $3,000 to $12,000 or more, installed. The exact cost will depend on the size of your home, the type of system (e.g. central air, heat pump, furnace), the efficiency rating, and your local market conditions.
Other factors that influence the cost include the complexity of the installation, whether any ductwork needs to be replaced, and the brand and quality of the equipment. Higher-efficiency models and systems with advanced features will be on the higher end of the price range. Getting multiple quotes from local HVAC contractors is essential to understanding the typical costs in your area.
