* 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 Northglenn Heating & Air Conditioning, Inc., our Lennox® cooling products use an ozone-friendly, chlorine-free R-410A refrigerant that meets strict guidelines laid out 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 bursting with energy efficient and cutting-edge technologies that will adjust your heating and cooling temperatures in tiny increments to keep a consistent temperature and a minimal amount of energy.
  • Lennox: First Air Conditioner with 26 SEER Rating
    We sell the first air conditioner to be rated 26 SEER* which means it’s one of the most efficient cooling systems on the market. Plus, the XC25 can substantially lower your monthly utility bills without sacrificing the cool temperatures you desire.
  • Reduce Utility Bills
    Living in Denver doesn’t have to necessitate 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 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 improve your systems’ operation efficiency. The gas heat is solely used when it becomes too cold for the heat pump to run efficiently, which can help lower your energy costs and keep your home more comfortable.
