Mike and his team are excellent. I called him to get a last-minute diagnostic check on our mini split AC unit that wasn't working on one of the hottest days in July. He was prompt, professional, and communicated clearly throughout the process. He also gave a fair quote for a replacement of the AC unit. I would absolutely work with Mike and the M&S team again.

My dad contacted him while I was at work and made a deal with him so I called him when I got him to make sure he was legitimate and not a scammer. He hung up on me after a few questions, which made me feel comfortable that he wasn’t scamming. He showed up the next day and installed a new furnace. Did a great job, got it done fast, and for a fair price. Would recommend him without question to anyone else.
