We Offer Some of the Most Energy Efficient Air Conditioners in the Main Line, Including the First Air Conditioner Above 26 SEER One of the most important features of an HVAC system is its energy efficiency, and that’s whywe offer Lennox® products at O'Brien Heating & Air Conditioning. That’s also the reason we are proud to offer the XC25, Lennox’s most efficient air conditioner. In fact, Lennox was the first manufacturer to offer an air conditioner to be rated higher than 26.00 SEER, or Seasonal Energy Efficiency Ratio, which measures the cooling efficiency of your air conditioner or heat pump. A higher SEER rating means higher energy efficiency, and as a the Main Line homeowner, you will likely appreciate the benefits that come along with these systems. First, they’ll help save the environment. But, you’ll probably be even happier to learn that highly efficient systems can help lessen your utility bills, potentially saving hundreds of dollars each year. The XC25 has also been recognized by the U.S. Environmental Protection Agency (EPA) by being designated as one of the Most Efficient ENERGY STAR®-qualified products in 2014. This recognition means the product blocks greenhouse gas emissions by meeting strict energy efficiency performance levels set by the EPA. The XC25 is one of a number of energy efficient air conditioners we offer in the Main Line.
