* 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 innovative technologies that will adjust your heating and cooling temperatures in tiny increments to keep a consistent temperature and a surprisingly small amount of energy.
  • Lennox Energy Efficient Air Conditioners
    At Farnell Mechanical, 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 its environmental impact.
  • 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 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 Opelika doesn’t have to mean high 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
    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 only used when it becomes too cold for the heat pump to run efficiently, which could help you save on your energy expenses and keep your home cozy.
