About the Lennox SL280V
The Lennox SL280V Elite Series furnace delivers two-stage heating with a variable-speed ECM blower — a combination that provides noticeably better comfort and efficiency than a basic single-stage furnace. The two-stage gas valve runs at low fire for most of the heating season, only stepping up to full capacity during the coldest Chicago nights.
The variable-speed blower circulates air more evenly throughout the home, reducing hot and cold spots and running quietly at lower speeds. This also improves air filtration performance since air passes through the filter more frequently.
D's Air & Heating, Inc. installs the SL280V with full permit pulling, load calculation, and warranty registration. It's a popular choice for Chicago homeowners upgrading from an older single-stage furnace who want meaningful comfort improvements without the cost of a modulating system.
