What is a good SEER2 rating for your air conditioner?

SEER2 , or Seasonal Energy Efficiency Ratio, measures the efficiency of your cooling system – the higher the SEER2, the more efficient the air conditioner. As of Jan. 1, 2023, the Department of Energy changed the minimum SEER2 ratings for heating and cooling systems. These minimum ratings vary by region, system capacity, and system type, so be sure to talk to your local independent Trane dealer to find the best system for your home.
