Our Story
The Story Behind D's Air
D's Air & Heating, Inc. was founded by Darryl Q. Joyner Sr., a Chicago-born HVAC technician who spent years working for large service companies before going out on his own. He saw firsthand how homeowners were pressured into maintenance contracts, upsold on replacements they didn't need, and turned away when they called a competitor's installer for help.
So Darryl started D's Air with a different model: show up, diagnose honestly, fix what needs fixing, and charge a fair price. No pressure to replace a system that can be repaired. No runaround about whose brand it is. We also offer maintenance agreements — and when you sign up, you get 15% off your next repair.
Today D's Air serves homeowners across Chicago and the surrounding Chicagoland communities — from Logan Square to Bridgeport, Oak Park to Skokie. Every call is handled personally by Darryl, and every job is backed by the same commitment to straight talk that started the company.
