I had an excellent experience with Windy City Air Conditioning & Heating. They showed up and went the extra mile in assessing the problem was with the ducts and recommended the right products that I needed to get everything fixed. I didn't have a problem with any of the workers and I was fine with the pricing, too. It was a five star experience and I would definitely recommend them to other people. I would say that the staff was honest, ethical, and professional, so you can't ask for much more than that! It was great work, so thanks for everything!
