Eight of East Coast Mechanical's nine reviews name the same technician: Josh. The Plymouth heating and cooling company says it was founded in 2024 and describes itself as family-owned, working the South Shore through the Cape and Islands on heating, cooling, ductless systems, ductwork, heat pumps and maintenance. What customers describe is a technician who explains the problem before he fixes it. A June 2026 Google reviewer came to him after a large HVAC company left their AC unit improperly reassembled and caused water damage; Josh picked up right away, got them in during peak season and walked them through what was wrong, why it happened and what he would do — "no upselling, no runaround." In May 2026 a household with a ductless system that wasn't keeping the house cool said he analyzed it, explained it clearly, and had everything working. An August 2026 reviewer had a small issue after a job, and Josh came right over and backed up his work. The longest account is from January 2026. A homeowner whose heat wasn't working, and who had heard nothing back from many other companies, got Josh's name from their mother. He fixed the heat pump, contacted the manufacturer and found the part was under warranty — saving thousands, by the reviewer's account, and getting the warranty extended five years — and reached out about the original installer's work, which got the rest of the bill covered. Another January 2026 reviewer, a 70-year-old woman, said he had her heat running within hours and later came out the same day for her daughter. The written reviews run from a June 2024 Thumbtack review, which names Joshua Crowley, to August 2026 on Google. The Better Business Bureau gives the company an A.
Josh is fantastic. He is very professional, detail oriented and great to deal with. We had a small issue and he came right over and backed up his work. If you’re looking for a honest, straightforward and smart professional to help with you HVAC needs, Josh is the guy. I can’t recommend him enough.
Could not recommend working with Josh and ECM more. The level of care and pride in his work is hard to come by these days and incredibly appreciated. Can confidently tell people I got a guy when any HVAC questions or concerns arise. Thank you Josh!
After a nightmare experience with a large corporate HVAC company that left my AC unit improperly reassembled — causing water damage to my home — I was understandably nervous calling someone new. Josh at East Coast Mechanical was exactly what I needed. He picked up right away, got me in quickly during peak season, and diagnosed the problem immediately. What stood out most was how he walked me through everything step by step — what was wrong, why it happened, and exactly what he was going to do to fix it. No upselling, no runaround, just honest straightforward work. If you're tired of the big corporate companies that treat you like a number, call Josh. He's the kind of technician you want taking care of your home. East Coast Mechanical has earned a customer for life.
We were having problem keeping our system, duckless aircondition cool. When Josh came, he analyzed the problem and explained the problem to us. His explanation was clear and easy to understand. When he was done, everything was working great! Josh, did a wonderful job! He will be our permanent maintenance from now on!
Josh is incredible, and saved us when our heat wasn’t working. After having reached out to many companies and them never getting back to me, I got a referral from my Mom after Josh had fixed her furnace. He got right back to me, asked questions before showing up, was there when he said he would be, was very nice and comfortable to have in the house, honest, very knowledgeable and took the time to show and explain the different issues in detail. Not only was he able to fix our heat pump (and make it run better than it ever has), he went out of his way to contact the heat pump manufacturer to see if it was under warranty (it was and he saved me thousands of dollars on the part by doing this and got my warranty extended 5 years!!!!!) He also contacted about the initial installer not installing correctly, and got the rest of the bill covered by them. I have never heard or experienced someone doing this before, and wouldn’t have thought to do those things myself. Truly, I cannot recommend him enough; he is the only person I will trust with future HVAC issues.
