Use the Lennox energy savings calculator to discover how much money you can save in the long-term on your energy bills by switching to a newer, higher efficiency HVAC system.

Compare savings across 5-year, 10-year, or 15-year timelines, a range of SEER ratings from 10 to 25 for air conditioning units, and a range of AFUE ratings from 60 to 98 for heating systems.

Customize the calculator to your home by selecting your current SEER or AFUE rating and energy costs (¢/kWH).
