Great Experience. I had a ton of questions and discussed my issue with multiple companies. I was in a bit of a bind because I had just moved in and a heatwave was in the forecast. I found CH&C the most knowledgeable, honest, and fair. I have worked in the trades for years and know a decent amount about all things housing, but when you get proposals from several companies and they are vastly different it becomes concerning. My family is in contracting and specifically my uncle owns an HVAC company that does not service my area. He said CH&C did exactly what he would have done and that they saved me a ton of money compared to the full replacement suggested by another outfit. I would recommend Chicago Heating and Cooling and will use them again for my heating and cooling needs. There is an art to working on furnaces and air conditioners. I feel confident with CH&C.
