Huntley's Full Service HVAC Experts

Subzero Heating and Cooling exists to raise the standard of comfort across Chicagoland — and we’re doing it without selling out. 
 

We’re independently owned, and our owner/lead technician personally oversees the majority of every install, bringing over 10 years of hands-on experience to each project. No corporate middlemen. No investor pressure. Just precision installation, premium equipment, and the kind of accountability that only comes when the owner is on the job. 
 

We believe an informed customer is the best customer- so we don’t just do the work, we show you the work. From camera inspections to full walkthroughs of every recommendation we make, you’ll see exactly what we see and understand exactly why we’re doing it. 
 

We stay ahead because we have to — ongoing training, up-to-date knowledge on every system we install, and a commitment to honest guidance from our first call to our final walkthrough.
