Furnaces are not measured with a SEER rating. The Seasonal Energy Efficiency Ratio (SEER) measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame.
Efficiency for furnaces, air conditioners and water heaters is measured in AFUE (Annual Fuel Utilization Efficiency). The AFUE of the Ruud Achiever 90 Plus furnace is up to 95%.
