I couldn’t be happier with the CSL Climate Control Co. performance, price, and service. Everything was as expected. As a licensed home inspector, I know good work when I see it. And these guys did incredible work. Technician was wonderful to deal with as the owner, who came out and bid the job. Would strongly recommend,

I have been using them to service my boiler for quite a long time now. Technicians are friendly and accurate, and they don’t rip you off.”

Technician worked longer than he had expected on a hot day to clean our filthy ductwork. He was professional and committed to find creative solutions for a very difficult job. (We also enjoyed his sense of humor.) We gladly refer the company, and Technician especially, to other potential clients.

We heard about this company from another customer and was satisfied with their work. The tech was ON TIME, courteous, and very thorough. And to top it off, they gave me the best estimate compared to 3 other companies in my area. This is one company I will definitely be referring!!!

My central AC broke during a heat wave. I called Technician after normal business hours. He was able to see me the next morning and very quickly resolved my problem. He was very professional and did a great job. I would highly recommend him and would use him again.

The technician arrived on time, quickly determined the problem. We called in the morning and he was at our house exactly when he said he would be. He had the problem with our unit fixed in no time. It was a real pleasure to have someone like him to help us out.
William, RIVERWOODS Illinoiss
Very professional organization. Immediate response. Had a super competitive quotation within hours. Outstanding turnaround; job was scheduled and completed within 3 days of initial quote. CSL Climate Control Co. installed two outdoor A/C units and one install was under less than ideal conditions but not a problem for Technician and his team. Another important point for me was after I met CSL Climaye control Co., I knew I could just leave the job to him and not worry about timetables, project management or security-conscious tenants. Absolutely First Class.

I am beyond pleased with this service. Extremely professional, on time and did a very thorough job. We recently acquired a very old home that was not maintained well. Our ducts were extremely blocked and probably were not cleaned for about 6 yrs. I was not only impressed with the equipment they used but they took actual photos for us to see how bad and filthy our ducts were. They spent a lot of time getting the job right with no additional fees. I would recommend them to anyone. We were extremely happy!
