Our 15 yo system wasn’t heating and the floor was vibrating. Our electric bill was out the roof. Seems one of our units blew a fuse and was running on emerg Heat. KCS knew what the problem was and replaced the unit with an energy efficient system within the week. Looking forward to our next electric bill! Thanks KCS – you guys are the best.

KCS saved us on a very, very cold day. Our furnace stopped working and they were able to assist us within hours of our initial phone call! Their communication was great and the work was very thorough. You earned a repeat customer and I’ll recommend your services whenever I get a chance. Thank you, thank you!

Just had our AC replaced today. KCS made the process painless! They were very easy to work with. They even made a temporary fix on our old AC unit until they were able to come out and replace our system. The technicians were professional, hard working, and showed up on time. Definitely recommend them to anyone.

I bought a house and the inspector said there was a gas leak on the water heater line. KCS scheduled my appointment very quickly, called with an arrival time update day-of and arrived precisely on time in the early part of the arrival window. They were super professional, fixed the leak quickly, and were extremely fairly priced. A great company for your HVAC needs!

I’ve used several companies in the past for my annual HVAC maintenance and KCS is by far the BEST! They went above and beyond by going out and purchasing filters for me because I forgot to purchase and drop them off. They even showed my tenant how to replace them. Lindsay was in constant communication with me, reminding me of my appointment, telling me when the tech was en route, and followed up with me once the technician left. They are honest, reliable, and such a pleasure to work with. Thanks KCS!
