Why Lennox Furnaces?
Chicago-Proven Heating Performance
Chicago winters demand a furnace that can handle sustained sub-zero temperatures without sacrificing efficiency or comfort. Lennox furnaces are engineered for exactly that — with AFUE ratings up to 99%, variable-speed blower technology, and modulating gas valves that maintain precise indoor temperatures regardless of outdoor conditions. D's Air & Heating, Inc. has installed and serviced Lennox furnaces in Chicago since 2009, pulling permits, registering warranties, and sizing every system to the home. No contracts, no pressure — just honest Lennox furnace work from a dealer who knows Chicago's climate.

Common Questions
Lennox Furnace FAQ
Which Lennox furnace is best for a Chicago home?▾
For most Chicago homes, the ML296V or EL296V offers the best balance of efficiency, comfort, and value. The ML296V delivers 96% AFUE with two-stage variable-speed operation at Merit pricing. The EL296V adds Elite Series build quality. For premium installs or homes with serious comfort challenges, the SLP99V's modulating technology is the best option available.
What does AFUE mean and why does it matter in Chicago?▾
AFUE (Annual Fuel Utilization Efficiency) measures how much of the fuel your furnace burns is converted to usable heat. A 96% AFUE furnace converts 96 cents of every dollar of gas into heat. In Chicago, where heating season runs from October through April, a higher AFUE furnace can save hundreds of dollars per year compared to an older 80% unit.
What is the difference between single-stage, two-stage, and modulating furnaces?▾
Single-stage furnaces run at 100% capacity whenever they're on, causing temperature swings and noise. Two-stage furnaces run at low capacity (around 65%) most of the time and ramp up to 100% on the coldest days — quieter and more consistent. Modulating furnaces (like the SLP99V) adjust output in small increments for the most precise temperature control and quietest operation.
Does D's Air pull permits for furnace installations?▾
Yes — always. Every furnace installation D's Air & Heating, Inc. performs in Chicago includes permit pull and inspection. This protects the homeowner's warranty, ensures the installation meets Chicago building code, and is required for proper Lennox warranty registration. We never skip permits.
How long does a Lennox furnace installation take?▾
Most residential furnace replacements take 4–8 hours depending on the model and any additional work required (flue modification, electrical upgrades, thermostat wiring). The SLP99V and SL280V typically take 6–8 hours. Merit Series installs are usually 3–5 hours. D's Air completes most installs in a single day.
