Chicago's Trusted HVAC Experts
999 Heating & Cooling is a locally owned and operated HVAC company serving Chicago and the surrounding suburbs. We are committed to delivering honest, high-quality heating and cooling service to every customer we serve.
Built on Honesty, Driven by Quality
999 Heating & Cooling was founded with a simple mission: to provide Chicagoland homeowners with the kind of HVAC service they deserve — honest, professional, and done right the first time.
We started as a small, locally owned operation and have grown by doing one thing consistently: treating every customer the way we would want to be treated. That means showing up on time, diagnosing problems accurately, explaining everything clearly, and charging fair prices.
Chicago winters are brutal and Chicago summers are no joke. We understand that a broken furnace or a failed AC is not just an inconvenience — it is an emergency. That is why we offer same-day and emergency service, and why we work hard to have technicians available when you need them most.
We are proud to be a Chicago company serving Chicago families and businesses. Every job we complete is a reflection of our commitment to this community.
