* 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 bursting with energy efficient and cutting-edge technologies that will adjust your heating and cooling temperatures in small increments to maintain a consistent temperature and a minimal amount of energy.
  • Lennox Energy Efficient Air Conditioners
    At Dial One Mears Air Conditioning & Heating Inc, our Lennox® cooling products use an ozone-friendly, chlorine-free R-410A refrigerant that meets strict guidelines set by the U.S. Environmental Protection Agency (EPA). This refrigerant can keep your system cooling effectively, while lowering the impact on the environment.
  • Lennox: First Air Conditioner with 26 SEER Rating
    We carry 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 reduce your monthly utility bills without sacrificing the cool temperatures you desire.
  • Reduce Utility Bills
    Living in Phoenix doesn’t have to mean 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, which can potentially decrease your annual energy expenses.
  • Dual Fuel Systems
    Pairing our gas furnace with an electric heat pump creates a dual fuel system that helps increase 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.
