Kao is awesome! He is professional, very knowledgeable and thorough. He explained his services well, was immediately responsive and provides a detailed before and after video showing the work he completed. He came equipped with a flip book manual which explained each part of our furnace using key parts to describe what was happening with our equipment. I will be using him every year for inspection and repairs when needed. He gave his honest advice for some issues we were having. I only wish their was a Kao in every home service profession! This is a great small business to support, I would highly recommend Climate Solutions.
