In my line of work across the Westside, I see a lot of contractors, but Keith at K and K Heating and Cooling is in a league of his own. He recently replaced our furnace in Rocky River, and the entire process was fast, professional, and perfectly executed. Whether you need a full HVAC replacement or just a seasonal repair, Keith is the guy to call. Highly recommended!

Highly recommend Keith at K & K Heating and Cooling! He’s knowledgeable, professional, and easy to work with. He takes the time to explain things clearly and answer questions, which makes a big difference when you’re dealing with heating and cooling concerns. It’s great to have someone you can trust who takes pride in his work. Thanks, Keith!
Corey, Jerry, Ian, and Nick were fantastic! From Corey diagnosing my issue, to Jerry walking me through my furnace options, to Ian and Nick installing my furnace - the entire process was quick, seamless, and professional! I am so happy I found K & K Heating and Cooling! If you're looking for a trustworthy company who will do what's best for you, pick K & K!!

We have 38year old Rheem gas furnace and Cory took really good care of it. Very friendly and knowledgeable young man. I was happy with no issues and speed it took to clean and inspect my furnace. I highly recommend K and K Heating and Cooling.
Thanks Cory for awesome job!
K and K rocks. We have been using them for years and never had any issues on the installation or repair work. Ian and Nick knocked it out of the ballpark like a Jose Ramirez homerun...
Every single time I call on K&K, they deliver. Responsive call representatives, knowledgeable technicians, and trusted service that continues to serve at the top level.
Not only have I used K&K for my own home furnace, AC, and mini-split system, I have also brought them to investment properties, and referred my clients to them. Each time they come through and keep things running smoothly. They are ALWAYS my trusted resource and will continue to be on the top of my referral list.
