Comfort you can feel good about
Along with the state of California, we’re leading the way with low-NOx initiatives and solutions. These NOx, or Nitrogen Oxide, emissions from gas furnaces produce ground-level ozone, which impacts the environment and your health. And we’re proud to say that Lennox is the first and only company to provide a full line of ultra-low emission furnaces. Learn more about our ultra-low emissions furnaces.
Two-stage operation for more balanced temperatures
A step up from single-stage furnaces because its gas valve offers an additional lower setting. Most of the time the unit will meet heating needs at its lower stage, resulting in balanced and consistent temperatures with lower energy use. Should the low heat setting not heat the space quickly enough, the furnace will switch to the high setting. This ability to switch between the two settings offers greater comfort and efficiency.
Energy efficiency that adapts to your needs
Equipped with the most efficient variable-speed blower motor available with the ability to slowly ramp the airflow up or down to provide consistently even temperatures as it only produces the necessary amount of airflow at any given time. Plus, variable-speed motors can run at a continuous low speed which allows for better air filtration and humidity removal.
iComfort® S30 ultra smart thermostat compatibility allows you to adjust your heating for energy savings based on your family’s routine.
The standard 80% AFUE means the SL280NV can reduce your heating costs, compared to an older furnace.
We have higher standards. Others think so, too.
