We Offer Some of the Most Energy Efficient Air Conditioners in the Bay Area, 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 Contra Costa Heating & AC. That’s also the reason we couldn’t be happier with the XC25, Lennox’s most efficient air conditioner. Actually, Lennox was the first manufacturer to introduce an air conditioner to be rated better 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 Bay Area 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 lower your utility bills, potentially saving hundreds of dollars year after year. The XC25 has also been acknowledged 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 several energy efficient air conditioners we offer in the Bay Area. Learn more details about our efficient products online or by calling Contra Costa Heating & AC at 510-343-9841.
