Duct Professor Heating & Cooling

Very professional, very courteous, very friendly. The installation of the furnace/ac went as expected. Thank you! Will definitely hire again. 10/10

Thank you Alex for sending your technicians to install my gas line properly today here in Chicago. After having several technicians fail to do it correctly these guys came and saved the day. It was done quick and most importantly right! Very professional and I would definitely use them again. Also, thank you Diana and Nicolette for assisting each time I called. —JB

Justin and Mario did a great job! They were punctual and professional. The went the extra mile to clean my dryer vent, which was difficult to get to. They showed me before and after pictures of the the vent cleaning. I really appreciated their friendly demeanor. I highly recommend this business.

Excellent company with top notch service! Very friendly and professional staff! Employees seem to enjoy working there as well. Dont look elsewhere, use duct professor!!!

We replaced our HVAC system with duct professor. It was a very good experience with Alex and his team. They came on time, worked throughout the day to complete the project and cleaned up before leaving. Would definitely recommend!

As a property manager that’s had dozens of service calls and installations over the years using several different HVAC contractors, I can confidently say that Duct Professor is the best you’ll find. The team is knowledgeable, professional, and take pride in their work. The team knocked out a complex new furnace and AC install for us, and the tenant reported that she hardly noticed they were there. A special shout out to Alex who was able to quickly troubleshoot an AC issue after another HVAC contractor botched up a new install just a few weeks before. Thanks, guys!

Ryan and Revy were on time and explained what could and could not be done. They were very courteous and made some suggestions for improvements to our indoor air quality.

I hired found Alex & his team on Thumbtack, and they were incredibly responsive, kind and straight forward. Like most customers, I had questions about why I needed certain services performed, but Alex and his team were kind enough to explain why we needed items/services, and it made the process incredibly fair and positive. Alex is a great business owner that answers the phone if you have questions, and someone all customers should support over larger companies. I strongly recommend!

Would have been 5⭐️ except that our yard gates were left opened and our dog got out. Also, left a mess under the outdoor dryer duct.

Mario and Justin were amazing! Talk about a dream team! They worked quickly and answered all of my questions. I appreciate their honesty and Justin is a great salesman. I love my new UV light on my furnace. I would 100% recommend Duct Professor!
