What Homeowners Say About Us

“I recently had an Air Conditioner and Furnace installed by M&K. I called around and talked with several companies, they have the best warranty and were the most knowledgeable when it came to answering my questions. Everything was installed perfectly and up to code in a timely manner. Very happy with the system and service!“​
