We Offer Some of the Most Energy Efficient Air Conditioners in Washington D.C., Including the First Air Conditioner Above 26 SEER One of the most important features you look for in an HVAC system is its energy efficiency, so it’s no wonderwe offer Lennox® products at Twin Air LLC. This also explains why we love the XC25, Lennox’s most efficient air conditioner. What’s more, 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 Manassas homeowner, you will likely appreciate the benefits that come with these systems. First, they’ll help save the environment. But, you’ll undoubtedly be even happier to learn that highly efficient systems can help lower your utility bills, potentially saving hundreds of dollars year after 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 impedes 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 Washington D.C.. Discover more specifics about our efficient products online or by calling Twin Air LLC at 703-666-8907.
