Energy Savings: Save up to an estimated 50% in energy costs with this unit. Estimated energy savings up to 50% based on our rated matched system. The majority of systems installed prior to 2006 are 10 SEER or lower. Potential energy savings may vary depending on your lifestyle, system settings, equipment maintenance, local climate, home construction and installation of equipment and duct system.

System efficiency is measured in SEER2, (Seasonal Energy Efficiency Ratio) and HSPF2 (Heating Seasonal Performance Factor). The higher the SEER2 and HSPF2, the greater the system’s energy efficiency, and the lower the overall carbon footprint of your household.
