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.

Jerry did a thorough job of inspecting and cleaning my 50+ year old boiler. He checked out every aspect of the system and it is running perfectly. He is knowledgeable and professional and his cheerful attitude was a plus! Service: Heating system maintenance

Chicagoland installed our new furnace years ago and everything was fine until we recently had our vents cleaned by another company and suddenly had a loud booming noise after the heat shut off. The technician came the day after I called, he explained what we were doing wrong, tested everything to be sure the noise had stopped. We couldn't be happier!
