Windy City Air Conditioning & Heating is an honest and reliable company. I have used various HVAC companies and Windy City is the one I keep going back to. They are responsive and good with communication. Their technicians arrive promptly and work efficiently. They conduct business honestly and do not try to upsell me on things that I do not need. Everyone is trustworthy, courteous, and pleasant to work with. I have had no problems with the service and am happy with all the work that they do. I have and will continue to recommend Windy City Air Conditioning & Heating to all my friends and family.
