Meet Leon & The Company
Leon's Heating and Cooling LLC is an owner-operated HVAC contractor based in Hanover Park, Illinois, proudly serving homeowners across the western and northwest Chicago suburbs.
Owner-Operated HVAC With Real Pride In Every Job
“When you call Leon's, you get me on the phone and on the job. I believe heating and air conditioning shouldn't be complicated or stressful — just honest diagnostics, clean work, fair prices, and treating your home with the same respect I treat my own.”
Leon's Heating and Cooling LLC was started with a single commitment: deliver reliable, high-quality HVAC work directly to homeowners without the big-corporate runaround. Operating out of 6830 Juniper St. in Hanover Park, we service neighborhoods across the entire western and northwest Chicago suburbs.
From sudden furnace failures on the coldest winter night to custom air conditioner replacements during summer heatwaves, we take the time to test thoroughly, identify the root problem, and explain your best options clearly before turning a wrench.
We service all major brands, carry top-tier diagnostic equipment, and stand firmly behind every installation, repair, and tune-up we perform.

We take immense pride in every condenser and furnace we install. Level gravel pads, neat line sets, vibration damping, and proper airflow calculations ensure your system runs quietly, delivers peak efficiency, and lasts for years to come.
