* 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 Energy Efficient Air Conditioners
    At Ilten's Incorporated, 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 Ultimate Comfort System
    Our Ultimate Comfort System is packed with energy efficient and new technologies that will adjust your heating and cooling temperatures in minor increments to keep a consistent temperature and a minimal amount of energy.
  • Lennox: First Air Conditioner with 26 SEER Rating
    We offer the first air conditioner to achieve a 26 SEER* rating which means it’s one of the most efficient cooling systems you can find. Plus, the XC25 can significantly lower your monthly utility bills without sacrificing the cool temperatures you want.
  • Reduce Utility Bills
    Living in Cedar Rapids doesn’t have to bring on high utility bills. In fact, a number of our HVAC products have earned the ENERGY STAR® label and high SEER* or AFUE** ratings because of their energy efficiency, which 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.
