About the Lennox ML17KC2
The Lennox ML17KC2 is the Merit Series two-stage central air conditioner condenser, available in 4 size configurations from 2 to 5 ton. Its two-stage compressor runs at low capacity on mild Chicago days — quieter, more efficient, and better at humidity control — then ramps to full capacity when temperatures climb. It's the right upgrade for homeowners who want more than basic cooling without moving into Elite or Signature Series pricing.
D's Air & Heating, Inc. installs the ML17KC2 with full permits, startup, and warranty registration. As a Lennox Premier dealer since 2009, we back every installation with our service guarantee and no-contract policy. Pricing shown is fully installed — no hidden fees.

What Chicago Homeowners Say
Quieter than I expected
The two-stage makes a real difference. It runs quietly most of the day and only kicks into high gear on the hottest afternoons. D's Air installed it fast and clean.
Marcus T. — Humboldt Park
Great value for the efficiency
Stepped up from a basic single-stage and the difference in my electric bill was noticeable. Darryl walked me through the options and didn't oversell.
Angela W. — Austin
No contracts, no hassle
Appreciated that D's Air doesn't require a service contract. They just do good work and stand behind it.

Why Choose D's Air & Heating, Inc.?
Chicago's trusted HVAC company since 2009 — licensed, insured, and committed to honest workmanship on every job.
Experience Since 2009
D's Air & Heating has served Chicago homeowners and businesses since 2009. Over 15 years of local HVAC experience means we've seen every type of system, every Chicago building configuration, and every challenge the city's climate presents.

D's Air & Heating holds Illinois HVAC License #2183457 and carries full liability insurance. We pull City of Chicago permits on every installation — protecting you legally and ensuring the work meets code.
Honest Recommendations
We tell you what you need — not what generates the highest invoice. If your system can be repaired cost-effectively, we'll say so. If replacement makes more sense, we'll explain exactly why. No pressure, no upselling.
Local Chicago Expertise
We know Chicago's housing stock — two-flats, greystones, bungalows, vintage buildings with steam heat, modern construction with forced air. We size and install equipment for the specific demands of Chicago homes and Chicago winters.
Long-Term Customer Support
Our relationship doesn't end at installation. We register your equipment for warranty, remain available for follow-up questions, and provide ongoing maintenance to keep your system running at peak efficiency for years.
What Chicago Homeowners Should Know About AC Installation
How a Central Air Conditioner Works
A central AC system uses refrigerant to absorb heat from indoor air at the evaporator coil (inside your air handler or furnace), then releases that heat outside at the condenser coil. The refrigerant cycle repeats continuously, cooling and dehumidifying your home. Modern systems use R-454B or R-410A refrigerant and achieve 16–26 SEER2 efficiency ratings.
Understanding SEER2 Ratings
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling output per unit of energy consumed. The federal minimum for Illinois is 14.3 SEER2. A 16 SEER2 unit uses roughly 10% less energy than a 14.3 SEER2 unit. High-efficiency variable-speed systems at 20+ SEER2 can cut cooling costs by 30–40% compared to older 10 SEER equipment.
Matched System Importance
An air conditioner condenser must be matched to the correct indoor coil (evaporator) and air handler or furnace. Mismatched components reduce efficiency, void manufacturer warranties, and can cause premature compressor failure. D's Air always installs matched, certified system combinations.
Cooling Design for Chicago Homes
Chicago's humid summers demand proper equipment sizing and refrigerant charge. An oversized AC cools quickly but short-cycles, leaving humidity high and comfort low. An undersized unit runs constantly and can't maintain setpoint on the hottest days. D's Air performs Manual J load calculations on every installation.
