We Offer Some of the Most Energy Efficient Air Conditioners in Erie, Including the First Air Conditioner Above 26 SEER One of the most important features of an HVAC system is its energy efficiency, so it’s no wonderwe offer Lennox® products at Patterson & Stirling Inc. 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 above 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 Erie homeowner, you may appreciate the benefits that come along with these systems. You’ll feel good knowing they’ll help save the environment. But, you’ll most likely be more excited to learn that highly efficient systems can help reduce your utility bills, potentially allowing you to pocket hundreds of dollars every year. The XC25 has also been recognized by the U.S. Environmental Protection Agency (EPA) by being named one of the Most Efficient ENERGY STAR®-qualified products in 2014. This recognition means the product prevents greenhouse gas emissions by meeting stringent energy efficiency performance levels set by the EPA. The XC25 is one of many energy efficient air conditioners we offer in Northwest Pennsylvania.
