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.
