Customer Reviews

Our customers speak for us

Joshua and Paul were very professional and showed up on time. Josh walked me through my entire inspection and answered all the questions I had for him. Customer service has also been excellent, which is a huge plus! Prices are fair, and I highly suggest using this company for any heating or HVAC needs.


Amazing customer service. We had an emergency and they came out very quickly. I think we were right outside of their perimeter but because it was cold and our heating went out they sent someone to fix the issue. Alan was our technician. He is very knowledgeable, efficient, and very straight forward with the issue. I really recommend this company and look forward to working with them in the future.


Highly recommend Chicago HVAC Repair Doctor, Inc. I recently moved into a condo, and had AC maintenance done. The Chicago HVAC Doctor team was incredibly responsive from the first scheduling call. They provided text updates the morning of the scheduled maintenance, and took the time to walk me through every step of their process. I will be calling them again in the fall for furnace maintenance!
