Got Diakin mini split system in our home late last fall. The service was prompt, and extremely efficient and Kasey's explanation of the system was very detailed. K&M was extremely busy on this day, but Josh went out of his way to personally come out and thoroughly explain in detail how to operate the system again. We are extremely impressed with this company. Would highly recommend!

We had an amazing experience with this heating company! They came out on a moment's notice when my grandma's furnace started leaking. Not only did they quickly diagnose and fix the issue, but they also went above and beyond by helping us get a large portion of the repair covered under warranty. Highly recommend to anyone needing reliable and trustworthy service!

Casey was amazing. Called and talked to him in the morning and they were out by 1:00. I would highly recommend.

I highly recommend K & M. I had them out for a furnace tune up recently -- it was quick, efficient, and fairly priced. The service technician was professional and friendly - we had a great time talking about our cats. I will definitely be using them again for my A/c tune up!

Casey and the team were beyond amazing. We had sub zero weather and our furnace broke in the morning. Casey came in the next couple of hours and the next day we had a new furnace. HIGHLY RECOMMEND. Professional, kind, reliable and local. We will be using them for our AC come spring and in the future all other services they provide.
