Posted on Google Brian BMay 27, 2026Trustindex verifies that the original source of the review is Google. I called a couple companies to fix my ac unit. Of which they only wanted to give me pricing on replacing my unit. “They said my unit was obsolete and no longer make the parts.” I called Machi, Stephen diagnosed my unit to intermittent relay failure on a board. He got the part that everyone else said they couldn’t get. My AC has been running flawless since. Thanks Machi. Wife and kids are happy and that’s what matters!!Posted on Google Kris KnerrMay 2, 2026Trustindex verifies that the original source of the review is Google. Great work. Had my boiler up and running in 2 hours after two other guys couldn't figure it out. Reasonable labor price. Fantastic job.Posted on Google Matthew DePraApril 6, 2023Trustindex verifies that the original source of the review is Google. Great guys and quality work!Posted on Google William GoldsteinDecember 21, 2022Trustindex verifies that the original source of the review is Google. One of the best companies we have ever dealt with. Responsive, professional, honest, reliable. We were referred through Brookline Plumbing for a hot water heat system repair on our old system and we are very thankful. Can’t recommend them enough!Posted on Google Tyler RichardsonJanuary 25, 2021Trustindex verifies that the original source of the review is Google. Our hot water heater failed right before Christmas and was replaced by a mediocre plumbing company. It wasn’t drafting and causing unburnt natural gas to leak into our home. Thankfully Machi Mechanical came to the rescue and got everything figured out for us. Machi quickly identified that the system that was installed by the other company was completely wrong and would never draft correctly due to the type of ventilation system existing in our home. We decided to go with a tankless system after hearing all of the benefits. Steve and Kevin worked non stop to get the job done right before Christmas. The attention to detail performed on this job is mesmerizing. There isn’t one piece of the system that isn’t level or measured perfectly. All of the soldering is flawless. They came with the promise of having hot water by the end of the day that they began the job and Machi Mechanical did just that. I will be a forever customer and I highly recommend you do the same.Load moreVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
