Yes, you should see a return on your investment (ROI) after installing a new HVAC system. The expected average ROI for residential HVAC replacement projects is about 30%. This means that you can expect to recover around 30% of the cost of the new system through energy savings in the first year alone.
The amount of money you save will depend on a number of factors, including the size and type of system, your climate, and your current energy usage.
