A recent customer said their AC stopped working on July 4 during an extreme heatwave, and that Ryan called back within minutes, was at the house within the hour and replaced the capacitor within minutes. That customer called the cost very reasonable. A recent customer said they had been told a broken heat exchanger meant replacing the whole thing, and that M&M replaced the exchanger only. A recent customer said Ryan came out the next day for cooling that shut off after a couple of minutes, and the issue was resolved in less than an hour. A recent customer said the installation of a new AC unit with spiral ductwork was quick. A 2026 customer said Nick and his team converted the house from oil heat and conventional central air to a high efficiency heat pump system with propane auxiliary heat and instant domestic hot water, a job with 4 zones. That 2026 customer said they did what they promised, in the time and for the price they promised. A 2022 customer who had a custom house built said there is no place from room to room or floor to floor where the temperature isn't exactly the same. A 2025 customer said they waited about three months for an answer to a question about service paid for a year earlier, and that the owner, reached by text, replied "call and schedule a service...I'm on vacation". That 2025 customer said a quick question answered by phone carries a $169 service fee.
