The service provided was exceptional! Dave came to my home and provided an estimate in writing and explained the work that would be performed. Dave was very kind, patient and professional. Joe and Jesus` installed a new furnace and AC unit, as well as replacing the lines and correcting mistakes from the previous install. I was extremely pleased with the service that was provided. They kept me informed throughout the install and were very courteous, knowledgeable and respectful. I would give Chicagoland Heating and AC 6 STARS!!

They were suppose to come out and repair something on my 1-2 year old furnace that they installed. They were a no call no show after I moved my schedule around to accommodate my scheduled appointment with them. I should have used another company to purchase my furnace.
