Easy to schedule my appointment. If I we needed to reschedule due to schedule ing conflict, they were accommodating.

Susan W.
Technician was knowledgeable, prompt, and thorough.

Connie G.
Had a great experience this morning with CC. They were able to come the next day and offered us 2 options for a fix. They went out of their way to be helpful and did not try to upcharge or upsell us. I would 100% call them again or recommend to others.

The owner, Jon, called me and provided personal service. The repair was easy and quick for a reasonable price. I love supporting local businesses, and Chicago Comfort is my new go-to for HVAC needs!

Daniel K.

Ms. B.
During a heat wave, I believed my a/c had stopped working. It was an holiday, 4th of July, and I called around to see if anyone could come out. Chicago comfort HVAC said they could come the next day. After Jon came out, he discovered that the a/c I currently had was a size too small. He gave me a quote to replace the a/c and also serviced the two other a/cs and did not charge me for the emergency visit. I am very happy with how quick they came out, got me a follow up appointment and now have a properly sized and function a/c. Will be using them for all heat and a/c concerns!

Joseph M.
Comfort HVAC was a very easy and nice company to work with. The timeliness and professionalism was stellar. I was provided multiple quotes to choose from right away. After each appointment a communication was sent immediately. They are very transparent. It was a pleasure to work Jon! Highly recommend.

Deanna N.

Jeanine H.
Jon was very easy to work with, communicated well, as well as working quickly and expertly. This was our second time hiring Chicago Comfort HVAC Services and they continue to provide stellar service.

Gideon G.
Chicago Comfort HVAC Services went above and beyond to say the least. Since my initial call, Jon’s customer service and attentiveness was exceptional. He remained very patient with me and answered all my questions with detailed responses. Upon appointment arrival, Jon and George were punctual. They showed me the equipment and voiced each part. Everything was exactly as it appeared in my initial quote. During installation, they made sure to explain important steps in the process when necessary. There were no surprises. They asked how we wanted certain aspects cosmetically, and they even made sure our basement door was locked. Thanks for your professionalism and overall great service Jon & George. I will be recommending Chicago Comfort to others.

Chris H.

Kenneth B.
Chicago Comfort HVAC were professional and on time. They also completed the job in a timely matter, even cleaning behind themselves.

Andrea H.
Chicago Comfort Controls has come through for the church again. He installed out boiler a few years ago and we needed some some work done on the pipes. Mr. Jon came through to take a look at the valves that were leaking. He adjusted what needed to be done and made sure that the church was in order. He didn't try to sell us some that we didn't need and he didn't price gouge us. Thanks for coming through for us as always Mr. Jon!

T D.
Jon was the absolute best. I had a boiler that had been giving me trouble off and on for several months. I made the worst mistake by calling four seasons. 7 different techs and none could solve the problem. I called Jons company out of desperation. He understood my exact boiler and the controller: I was able to communicate all of the issues over the phone and he determined it was a sensor. I was so relieved. He installed the sensor and so far so good. I would definitely recommend.

Felicia B.
My furnace died and this company came in and installed a new system in a few days from ordering the unit to installation. Thank you for everything!

myplace F.
I used Chicago Comfort HVAC Services when my furnace suddenly started giving out a burning smell. We replaced our furnace and AC and Jon was amazing. They are professional arriving on time and explaining everything in detailed fashion. They keep their work place clean and are very very affordable. I cannot recommend their services enough. I would never use anyone else. They are amazing, professional, courteous, and affordable.

Danielle R.
Knowledgeable, professional, punctual and courteous! Thank u

Brenda R.
Very professional straight to the point

Clyde H.
Tech arrived on time. Service rendered professionally. Tech addressed concern about heater lighting excessively.

Robert R.
Comfort Hvac came to my home, diagnosed my furnance and told me what the problems were. They also took the time to explain what the problems were to my insurance company. COMFORT HVAC installed my furnance FOR HALF...LET ME REPEAT FOR HALF THE PRICE OF WHAT FOUR SEASONS WANTED TO CHARGE ME!!! THIS COMPANY HAS ALL THE HVAC COMPANIES BEAT!! IF YOU THINK I AM LYING CALL FOUR SEASONS FIRST AND THEN GET A SECOND OPINION FROM COMFORT HVAC AND SAVE SOME MONEY. WITHOUT SACRIFICING QUALITY, EXPERTISE AND ETHICS.

Eldridge S.
Spent the last week without heat as my furnace went out and due to a misunderstanding, I would have gone longer. Jon thanks so much for coming in and working with me! His troubleshooting and resolution skills are PHENOMENAL. He literally went above and beyond to make sure that I had a working furnace. I truly appreciate it, he kept his promise!
