What is the best Lennox air conditioner for a Chicago home?

For maximum comfort and efficiency, the SL28XCV Signature Series is the top choice — variable-capacity inverter technology, top-tier SEER2, and ultimate humidity control. For a great mid-range option, the EL18XCV Elite offers variable-capacity performance at a lower price point. For budget replacements, the 16ACX or 14ACX Merit Series deliver reliable Lennox quality at an affordable price.

What does SEER2 mean and why does it matter?

SEER2 (Seasonal Energy Efficiency Ratio 2) measures how efficiently an air conditioner cools your home over a full season. Higher SEER2 = lower energy bills. Variable-capacity units like the SL28XCV achieve top-tier SEER2 by running at partial capacity most of the time, which is far more efficient than single-stage units that cycle on and off at full power.

How much does a Lennox AC installation cost in Chicago?

Lennox AC installation in Chicago typically ranges from $2,200 for a basic Merit Series unit to $9,500+ for a top-tier Signature Series system. Pricing depends on the model, tonnage, existing ductwork condition, and any required electrical or refrigerant line work. D's Air provides upfront pricing with no hidden fees.

Do you pull permits for Lennox AC installations?

Yes — D's Air & Heating, Inc. pulls all required City of Chicago permits for every AC installation. This protects your warranty, ensures code compliance, and is required for homeowners insurance coverage on new equipment.

What size Lennox AC do I need?

AC sizing depends on your home's square footage, insulation, window count, and sun exposure. D's Air performs a proper Manual J load calculation on every installation to ensure the right tonnage. An oversized AC will short-cycle and leave your home humid; an undersized unit will run constantly and never fully cool the space.
