Outstanding service from Alliance Mechanical Services LLC! Our power went out during an ice storm and came back on the next day, but the HVAC did not. We called Alliance mid-afternoon and was told Linnie would be calling us back to schedule a visit. Less than an hour later Linnie called and said he was on his way. Turned out that even though there is a breaker for it in the main panel, there was also a breaker enclosed in the system beneath the house. Linnie turned it back on and we had heat. While with us, he shared a wealth of helpful information, his knowledge was matched by his enthusiasm. A couple hours later we realized we were cold and found the system had cut off again, so I texted Linnie, who returned the next morning and replace the breaker, no additional fee. All this during

We are giving Lennie and his team a five-star for service, dependability, and knowledge. His team has serviced several residential and commercial businesses for us and we are happy to recommend to others in Middlesex and surrounding counties. V and G Dozier 12/12/2025

Excellent service! Linnie and his folks have been installing and servicing our systems for many years. We’ve have and will continue to recommend him to others. Recently fixed one of our older systems and did an exceptional job. We like his philosophy of preferring to fix something instead of immediately selling you new equipment. Tries to save his customers money. Much appreciated.

Lenny Saved our biggest weekend of the year! By squeezing us in to his already tight schedule, he got our Food Truck Refrigerator Freon recharged and back in business. We Highly Recommend Alliance!

I have worked personally with Linnie, he is a phenomenal craftsman with 17+ years of experience in the trade. Great prices and honest work. Highly recommend.
