Just wanted to take a minute to thank you for the hard work you did in my townhouse. The new unit is working Great and keeping the whole house very comfortable. I also wanted to thank you for being able to squeeze us into your schedule in this busy for you time of year. The install looks great and I can already tell by using it that it will be saving money on our monthly utility bill. I will definitely be recommending you to anyone I come across who may need heating and a/c work. Thanks Job Well Done! Sincerely, Tom Pilasiewicz.

One Saturday morning this winter we discovered our furnace had stopped working. I called several companies and Chicago HVAC was the only one that was answered by a live person. They were able to send someone out that afternoon who promptly and professionally fixed the problem. Ana Sue, Wrigleyville Area, Chicago.

We just wanted to thank you and your helper for the wonderful job you did installing our new tankless water heater. Our experience with You at your company has been wonderful. Martin and Anna from Glencoe IL.

The service tech was very helpful and explained everything in detail. They also have done the work for both of my kids within the last year. I would recommend them to anyone. John C. Chicago IL.
