Mike did an amazing job. He was very thorough during the initial visit and found a leak that a different company could not find. He did a great job with the repair. We highly recommend him.

Mike is extremely knowleable, honest and an expert at what he does. He found and fixed numerous issues from our past AC company that we use to use. He's also very detailed and did a really fantastic job. They were always on time during multiple visits, communicated exactly what they were doing, what they recommended, and got the job done as described, and even went above and beyond. I highly recommend Supreme Mec…
