Windy City Air Conditioning & Heating did a great job for us! This was our first time using them. We found their ad in Spirit Magazine so we gave them a call. We had them come out to fix a pipe in the attic that was leaking. When we called they rearranged their schedule to get someone out right away for us. The technician that came out was prompt, polite and professional. He was conscientious and pleasant. He was respectful of our home. He assessed the problem then explained that he would blow out the piping to get rid of the excess water and rearrange the area for the drip pan to stop the condensation. He did well because it is no longer leaking. I feel they were reliable and honest. So I would tell anyone looking for air conditioning or heating services to call Windy City Air Conditioning & Heating without hesitation.
