* SEER, or Seasonal Energy Efficiency Ratio, measures the cooling efficiency of your air conditioner or heat pump. A higher SEER rating means greater energy efficiency and more savings for you and the environment.

** Annual Fuel Utilization Efficiency (AFUE) measures how efficient the appliance is in converting its fuel’s energy into heat over the course of a year.

  • Lennox Ultimate Comfort System
    Our Ultimate Comfort System is packed with energy efficient and new technologies that will adjust your heating and cooling temperatures in small increments to preserve a consistent temperature and a very small amount of energy.
  • Lennox Energy Efficient Air Conditioners
    At Hix Air Conditioning Service, Inc., our Lennox® cooling products use an ozone-friendly, chlorine-free R-410A refrigerant that meets strict guidelines put forth by the U.S. Environmental Protection Agency (EPA). This refrigerant can help your system cool effectively, while lowering harm done to the environment.
  • 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 available. Plus, the XC25 can measurably lower your monthly utility bills without sacrificing the cool temperatures you desire.
  • Reduce Utility Bills
    Living in Muskogee doesn’t have to bring on expensive utility bills. In fact, many of our HVAC products have earned the ENERGY STAR® label and high SEER* or AFUE** ratings because of their energy efficiency, which can potentially save on your yearly utility expenses.
  • Dual Fuel Systems
    Combining our gas furnace with an electric heat pump creates a dual fuel system that helps enhance 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.
