HVAC Repair & Installation — Chicago
How much does furnace repair cost in Chicago?+
Most furnace repairs in Chicago range from $150 depending on the part. Common repairs include igniter replacement ($180), gas valve replacement ($350), and heat exchanger repair ($500). D's Air charges a Technical Visit — $95.35 that covers travel, fuel, diagnostics, and technician evaluation. This fee is separate from repair costs.
How much does AC installation cost in Chicago?+
A central air conditioner installation in Chicago starts at $3,500 for a standard 2–3 ton residential system, including equipment and labor. High-efficiency units (16+ SEER) run higher. D's Air provides upfront pricing before any work begins — no surprise charges.
Do you service all HVAC brands?+
Yes. D's Air services all major brands including Lennox, Carrier, Bryant, Trane, Goodman, Amana, Rheem, Ruud, Payne, and more. We carry common parts on the truck to complete most repairs in a single visit.
How long does a furnace last in Chicago?+
Most gas furnaces last 15–20 years with regular maintenance. Chicago's harsh winters put extra strain on heating systems, so annual tune-ups are especially important. If your furnace is over 15 years old and needs a major repair, replacement is often the better investment.
Do you require a service contract?+
No. D's Air does not require service contracts or maintenance agreements. You pay only for the work you need — starting with the Technical Visit — $95.35, which covers travel, fuel, diagnostics, and technician evaluation.
What areas of Chicago do you serve?+
We serve Chicago and the surrounding suburbs including Logan Square, Wicker Park, Humboldt Park, Oak Park, Evanston, Berwyn, and more. Call (773) 940-0965 to confirm service availability in your neighborhood.
How quickly can you respond to a no-heat emergency?+
D's Air offers same-day and emergency HVAC service throughout Chicago. For no-heat emergencies in winter, we prioritize dispatch. Emergency service calls are $149, required at booking through Housecall Pro.
What is a SEER rating and why does it matter?+
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner cools your home. The higher the SEER, the lower your monthly energy bills. Illinois requires a minimum of 14 SEER for new AC installations. High-efficiency units (18–21 SEER) can cut cooling costs by 30–40% compared to older systems.

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.
HVAC Education — What Chicago Homeowners Should Know
How Your HVAC System Works Together
A complete HVAC system includes a heating source (furnace or boiler), a cooling source (air conditioner or heat pump), air distribution (ductwork or hydronic piping), and controls (thermostat). Each component must be properly sized and matched to work efficiently. D's Air installs and services all components as a complete system.
Chicago's Climate Demands
Chicago experiences some of the most extreme temperature swings in the country — from -20°F wind chills in winter to 100°F heat indexes in summer. Your HVAC equipment must be sized and installed to handle both extremes reliably. D's Air has served Chicago since 2009 and understands what local homes require.
The Importance of Annual Maintenance
Annual tune-ups extend equipment life, maintain efficiency, and catch problems before they become failures. A well-maintained furnace lasts 20+ years. A neglected one may fail at 12–15 years. D's Air offers annual maintenance plans for both heating and cooling equipment.
Energy Efficiency and Savings
Upgrading from a 10 SEER AC to a 16 SEER unit cuts cooling costs by roughly 37%. Upgrading from an 80% AFUE furnace to a 96% AFUE unit cuts heating costs by about 17%. Over 10–15 years, these savings typically exceed the cost difference between standard and high-efficiency equipment.
