Chicago Heating & Cooling Corp. was recommended to me by a former neighbor. I am so glad I called them. Matthew and Marcus completed a very complex AC repair at my condo unit over 2 days. They were on time, professional, courteous, and very careful with my property and possessions. Their pricing is fair and competitive. I cannot recommend them highly enough. If you have any HVAC or major appliance repairs, look no further. You won't regret hiring them. I recommend them to everyone I know who needs these types of repairs.
