    We came home from work and our furnace was not running. I called several places but no one could come out or it was going to cost a lot of money, so we were stuck. However, upon getting a recommendation from a friend, we called KCS and I am so glad we did. They were able to come right over and diagnose the issue. It could not be fixed last night, but they were here first thing in the morning and we have heat! KCS helped us out and was extremely professional and made sure we were taken care of. I would recommend them to anyone in the area and we WILL be using them again in the future (hopefully not too soon)

    Came home a freezing home tonight and the furnace not clicking on. Of course it’s in the single digits so I was freaking out! I called my homeowners insurance thinking they would be able to help me since it’s the service I pay for…they said 24 hours would be the earliest available technician. I got a referral to KCS and within 30 minutes someone was at my door. He came in, solved the problem and was on his way! I can’t thank you enough! I will definitely be contacting you again! Merry Christmas!

    Bottom line up front: KCS is a great company! Always professional, on time, and helpful, their techs Neal Kinchloe and Marlon Berrera went out of their way to get the job done – under extremely difficult circumstances. When my ancient air conditioner expired of natural causes, a home warranty company sent KCS to take a look and make a (cheap) recommendation. What the warranty company couldn’t know when they sent KCS was that the company would put its client first, even if it cost them! That kind of integrity and honesty is rare nowadays.

    We are extremely happy with the KCS team and their services. On the several occasions we have called them, they were easy to communicate with and were always able to schedule an appointment in a short amount of time. They always come out within the scheduled time discussed and are extremely professional. We love that they can diagnose the program and fix it on the spot. We would highly recommend this company!
