Prices for new HVAC systems can vary dramatically. Some factors that affect pricing are the size of the system (based on the size of your home), the type of system (oil, gas, etc.), and the efficiency rating (the higher the rating, the higher the initial cost). Most systems will range in price from $5,000 to $8,000, based on a combination of these three factors.
