Matt and his coworker did a fantastic job removing my old water heater and installing my new water heater. They were friendly and courteous. Professional's all the way. Recommend them to anyone needing a water heater replaced.

Alex came to my house to look at my AC unit because it stopped blowing any cool air. He was honest in saying it couldn’t be fixed (unit is at least 25 years old, was on borrowed time anyway) and it needed replacing. Alex is very good at what he does. He is very knowledgeable and honest, and it’s appreciated.

Jason is a great salesman. Cody is a wonderful installer. Explained everything. Did a great install. Cleaned up. The new AC looks beautiful. I checked the metalwork in the basement. Shout out to Brian who is a skilled metal craftsman. The quality of the product and integrity of the team are outstanding. I highly recommend Kotz.

Jason was super relatable and kind during our initial quote for a new furnace, and he even showed up during the installation to check in! Communication with Kotz was seamless and they really helped us out in a time of need. Denny B installed our new furnace. He is very smart and efficient and he kept everything clean. The furnace looks great. Thank you to Brian for the great materials as well. Would highly recommend Kotz.

I called Kotz Heating and Cooling when my HVAC system stopped functioning correctly. They were able to replace my 35 year old air conditioner the very next day. They also spent a long time updating some furnace components. I am grateful for their hard work and the long hours they spent making my home more comfortable and safe. Allen, Jason and the installation team did a wonderful job. Would 100% recommend.

Bob was just fantastic on our upgrade today! On time, no pressure, very friendly, courteous, and efficient. Installed a "smart valve" that automatically shuts off our water if it senses a leak, which is now required from our insurance company. We love the team at Kotz! They are professional, prompt, great communicators, and a company we love to refer to our clients and friends. I would give them 6 stars if I could!
