Energy Efficiency

The rules have changed! The energy efficiency requirements for new gas furnaces are much higher than the requirements your current furnace had to meet. Bring your home's energy efficiency up to date with the Lennox SL280V Variable Speed Gas Furnace, and save hundreds every year!

  • Energy Efficiency Rating: The SL280V offers you the new standard in energy efficiency with its 80% AFUE rating.
  • Boosts Cooling Efficiency: The furnace's blower motor is responsible for delivering cold air to the rooms within your home as well! The variable speed operation of this motor will help eliminate waste during the summer season and could increase your Lennox air conditioner's SEER rating as well!
  • Dual-Fuel Capability: This gas furnace can be paired with an electric heat pump to further increase your savings. The system will be able to determine which fuel would be most efficient to use based upon the weather and the comfort demands of your home.
  • icomfort™ Enabled Technology: Have Four Seasons install an icomfort Touch® thermostat for user-friendly temperature control. It employs Touch technology that allows you to quickly change and adjust your settings so that you can get the most out of your new furnace!
  • Enclosed Blower Compartment: By sealing the blower compartment on your furnace, the system is able to minimize losses and deliver as much warm or cool air as possible to the target rooms in your home.

Quiet Operation

If the goal of your new furnace installation is to eliminate excessive operating noise, then the SL280V is the right gas furnace for your home! SilentComfort™ technology employs several different technologies and improvements that all work together to create a furnace that is considered to be the quietest heating system in its class.

  • Quietest Furnace in this Class: Unlike single speed blowers that only operate on "High," the variable speed blower in your SL280V slowly ramps up to the speed required to maintain comfort within the home. By eliminating abrupt start-ups and shut-downs, this unit operates at a noise level that is virtually undetectable.
  • Noise-Reducing Materials: Lennox has lined this heating system with sounds absorbing materials that contain any noise within the unit leaving you with a whisper quiet furnace.

Home Comfort

You could have the quietest or most efficient furnace in your home, but it wouldn't be worth much if it couldn't keep you and your family comfortable. The SL280V delivers everything you could want from a new furnace including home comfort.

  • Two-Stage Operation: Varying output from "high" to "low" gives this gas furnace the flexibility to conserve energy while keeping temperatures in the home consistent with what you have set on the thermostat. This feature eliminates the temperature swings that are common with single stage systems.
  • Variable Speed Technology: Your Chicago HVAC system is responsible for more than just keeping your home warm and cool. This system also manages humidity and air quality! The variable speed technology in the SL280V Gas Furnace provides a consistent flow of air through your humidifier and furnace filter. The result is better humidity control and cleaner air within the home.
  • Ultra-Low Continuous Fan: This super quiet fan keeps air moving at all times to support accurate home temperatures, indoor air quality, and humidity balance, and it does all of this without wasting large amounts of energy.
