CSL Climate Control Co.

CSL Climate Control is the BEST HVAC company we ever used. The techs are knowledgeable and professional. They are always quick to respond. Will recommend them to anyone that needs commercial or residential service as we use them for both, and we couldn't be happier with the service, price and quality.

I used CSL Climate Control for my annual furnace cleaning and checkup. The technician was pleasant, courteous and very competent. He thoroughly checked out the furnace and took the time to explain how some parts worked - so I understood what he was doing and what he was checking. He inspired confidence and I will definitely use CSL again.

Great company. Not only are their prices competitive they are always on time. They service most of my family from the suburbs to downtown Chicago. My son lives in a high-rise downtown and his furnace went out unexpectedly and the unit is in a very difficult spot to gain access. 2 other companies quoted 2 times the amount to as CSL to replace the unit. They located the unit and installed it within 48 hours. Now that's service. Thanks again CSL

Rebecca was extremely helpful in getting a tech out to me at a time when many companies were not taking calls. I appreciated her willingness to help during such a busy time and the technician that came out to service me, knew exactly what was happening! He was very knowledgeable and helpful. I’m grateful they were able to get my unit back up and running and gave me options to work with. I would recommend working with CSL, they will not disappoint you!

The Climate Control installers and technician Dominick were knowledgeable and worked with great integrity throughout the entire installation process! Installing a new boiler was very costly and Rebecca was able to help me find a more cost effective option. Most importantly, every staff member, we interacted were very committed to provide us with fair and honest services. My 20+ years heater technician/owner retired. I hope Climate control will be my next dependable and trusted provider!
