Ruud Gas Furnace Efficiency Over Time
Ruud has continuously improved efficiency to meet evolving federal standards. In 2006, the minimum was raised to SEER 13. In 2015, southern states moved to SEER 14. In 2023, new SEER2 standards took effect: 14.3 SEER2 (South), 13.4 SEER2 (North). Modern Ruud models range from 14 to 26+ SEER.
Regarding refrigerants: Ruud units before 2010 likely use R-22 (phased out since 2020 -- expensive and harmful). Units from 2010-2023 use R-410A. Newest models use R-32 or R-454B to meet EPA regulations. Knowing your refrigerant is critical -- R-22 refills cost $100-200+ per pound.
