ENERGY STAR is a certification program run by the U.S. Environmental Protection Agency (EPA) that identifies products meeting strict energy efficiency standards. HVAC equipment earning the ENERGY STAR label is significantly more efficient than the minimum required by federal law.
For HVAC, ENERGY STAR certifies central air conditioners, heat pumps, furnaces, boilers, water heaters, and smart thermostats. Requirements are updated periodically as technology improves. Currently, ENERGY STAR certified central ACs must achieve at least 15.2 SEER2, and certified heat pumps must meet minimum SEER2 and HSPF2 thresholds.
ENERGY STAR equipment qualifies for utility rebates and may qualify for federal tax credits. The program estimates that ENERGY STAR certified HVAC equipment can save homeowners 10-20% on heating and cooling costs compared to standard equipment. Always look for the blue ENERGY STAR label when purchasing HVAC equipment.
