Windy City Air Conditioning & Heating came out to my home for the first time. I recently had them repair my air conditioning unit and everything turned out just fine. I think that the technicians that they sent out were knowledgeable and did what they were supposed to do to complete the work. I think they tried to go for a hard sell at the end which I did not care for but otherwise was okay. I probably would recommend them to others for some things but not all, and I maybe would call on them again for myself. For the work that they did, I felt that the pricing was fair and reasonable.
