They came out promptly to give us a second estimate to replace the furnace in our condo. Gave us a price that was thousands less than what we received from the biggest supplier with comparable equipment. Installed within 24 hours and all is working well. Highly recommend.

“Highly recommend.”
Highly recommend! We had Chicago HVAC replace our steam boiler (and thermostat) in our 1910-ish home, and cannot say enough good things about their thoroughness, timeliness, and professionalism. They also really took the time to educate us on what exactly needed to be done and why. Kudos to Joshua, Jesse, Rafael and Louis (and also a big shout-out to their in-office/admin team who’ve also been super helpful and responsive all along the way!).

“Alfonso saved the day.”
Alfonso saved the day. He came to service our newly installed humidifier that wasn't functioning (not installed by them). And also found that the wiring for our newly installed furnace was wrong and contributing to the humidifier not working. He rewired all of it and I'm so relieved! We knew our original installer cut corners and I'm so glad we decided to hire a new technician to make sure it was all safe. Thanks Alfonso!

“We have been using this group for many years now.”
We have been using this group for many years now. They were the first people we called when we had to have our original HVAC replaced, and we had an issue with our external natural gas line this winter and they came very promptly to help reengage with the furnace. Very kind and courteous, and the cost is very reasonable

If I could give more than 5 stars I would. Rafael came out on an emergency call on a Sunday in a very timely manner. He quickly diagnosed the problem, took his time to fix it and double checked everything. Chicago HVAC Repair Doctor is always honest, fair and of course does high quality work!!
