  • Lennox: First Air Conditioner with 26 SEER Rating
    We sell the first air conditioner to earn a 26 SEER* rating which means it’s one of the most efficient cooling systems on the market. Plus, the XC25 can significantly lower your monthly utility bills without sacrificing the cool temperatures you want.
  • Reduce Utility Bills
    Living in Carpentersville doesn’t have to bring on outrageous utility bills. In fact, a variety of our HVAC products have earned the ENERGY STAR® label and high SEER* or AFUE** ratings because of their high efficiency levels that can potentially reduce your annual utility expenses.
  • Dual Fuel Systems
    Connecting our gas furnace with an electric heat pump creates a dual fuel system that helps improve your systems’ operation efficiency. The gas heat is used only when it becomes too cold for the heat pump to run efficiently, possibly saving you money and keeping your home cozy.
