That’s why we carry Lennox® products, and that’s why we carry the XC25 high efficiency air conditioner. It’s the first air conditioner rated at more than 26.00 SEER. SEER, or Seasonal Energy Efficiency Ratio, measures the cooling efficiency of your cooling system. The higher your SEER rating, the better your energy efficiency. As a homeowner in the Main Line, you may want an energy efficient air conditioner for two reasons. For one, you could reduce your monthly utility bills. Second, you’ll help the environment. This product was designated as one of the Most Efficient ENERGY STAR® qualified products in 2014, meaning it helps prevent greenhouse gas emissions by meeting strict energy efficiency performance levels put forth by the U.S. Environmental Protection Agency (EPA). From solar capabilities to our Precise Comfort® technology, the XC25 is just one of many energy efficient air conditioners we offer in the Main Line.
