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.
Manufacturer-Trained Technicians
Our technicians receive ongoing manufacturer training and certification. We install Lennox, Goodman, Amana, Daikin, Sinclair, Weil-McLain, Peerless, and other leading brands — and we know each system inside and out.
Licensed, Insured & Permitted
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 Furnace Replacement
How a Gas Furnace Works
A gas furnace draws in return air, heats it through a heat exchanger using a gas burner, and distributes the warm air through your ductwork. Modern high-efficiency furnaces (90%+ AFUE) use a secondary heat exchanger to extract additional heat from combustion gases, dramatically reducing energy waste compared to older 80% AFUE units.
Warning Signs Your Furnace Needs Replacement
Age over 15–20 years, rising energy bills, uneven heating room to room, frequent cycling on and off, yellow or flickering burner flame, unusual noises (banging, rattling, squealing), and carbon monoxide detector alerts are all signals that replacement may be more cost-effective than continued repairs.
Choosing the Right Efficiency Level
For Chicago's cold winters, a 96%+ AFUE two-stage or variable-speed furnace delivers the best long-term value. Two-stage operation runs at lower capacity most of the time, reducing temperature swings and improving humidity control. Variable-speed blowers further improve comfort and air filtration efficiency.
Proper Sizing and Load Calculations
An oversized furnace short-cycles — it heats quickly, shuts off, and repeats — causing temperature swings, excess humidity, and premature wear. An undersized unit runs constantly and still can't keep up on the coldest days. D's Air performs Manual J load calculations on every installation to ensure the right equipment size for your home.
Airflow, Static Pressure, and Ductwork
Even the best furnace underperforms in a poorly designed duct system. D's Air measures static pressure and airflow on every installation. If your ductwork is undersized or leaking, we identify it before installation — not after — so your new furnace delivers the comfort it was designed for.
