KTS Heating & Air Conditioning Repair

heater malfunctioned in sub/freezing temps.
Very impressed with this company and the service. Kris and John were great and they took the time to explain all the work that was going to be needed to get that heat back on . My dog really liked them too and he is an excellent judge of character! Very much appreciated and would highly recommend this company. KTS rocks!

KTS is absolutely superb. As a PM managing multiple, both residential and commercial projects throughout Chicago - I have nothing but good things to say about this companies professionalism, effeciency and clear communication. John with KTS provides us with on-time estimates, honest scheduling and transparent pricing. KTS easily makes themselves our go-to A-team HVAC guys.

Called KTS around 10AM regarding a burst boiler radiator and some damaged water valves. Kris and John were very professional and arrived sooner than estimated; the team was able to get all my water issues resolved in a quick, clean, and efficient manner. Would recommend these guys to anyone with a hydronic based heating system.

I have used this company at multiple sites. They are very professional. John is very prompt at getting information to you, and will take the time to clearly communicate issues, choices and solutions available for each project. Kriss and Carl showed up on time, did great work, and cleaned up after themselves. I will definitely use their services again.

Highly recommend this company!! John(owner) is an awesome, genuine guy! Honest prices, great work! He has been my go to HVAC company for years and will always refer him.

I can't say enough good things about KTS. I had several HVAC contractors come look at my system, all of whom declared it too old to salvage and gave me a replacement quote. John and his apprentice busted out tools, began troubleshooting, identified a couple of easy-fix problems, and had me up and running within an hour at a very fair price. No hard sell, but his replacement quote (provided just in case) was among the best I got that day. Great communication and explanations, and even a check-in a few days later! These guys really earned the 5 stars.

John at KTS is an incredible resource for all hvac needs. He is always cheerful and on time, responsive, knowledgable and efficient. A joy to work with and highly recommended.

KTS is reliable, professional and detail oriented. They are willing to go the extra mile to make sure customers understand the services and the associated costs. I would not hesitate to schedule with KTS again!

John is efficient and detail oriented. KTS won't be the least expensive option but they produce work with high quality workmanship and always suggest the correct systems for your project.

Would definitely go through them again. Reliable and professional work ! When no one had time to fix my AC mid summer , KTS made time to get it done. Highly recommend
