East Coast Mechanical is a family-owned, local HVAC company in Plymouth, Massachusetts, founded in 2024. Its stated work includes heating and cooling, ductless systems, ductwork, heat pumps, air quality, and maintenance, and its website says it serves the South Shore through the Cape and Islands. Recent Google reviews and a Thumbtack review describe prompt responses, clear explanations, careful repairs, clean work, and successful heating and cooling service. Several reviewers specifically mention quick diagnosis, same-day help, and follow-through on warranty questions. The written history is recent, covering 2024–2026, and is strongly positive, though the sample is limited. Before booking, confirm the exact project scope, parts and warranty terms, permit responsibilities, and the availability of the advertised emergency service. The company’s website states a 100% guarantee and factory-trained technicians; these are self-reported claims, so homeowners should request the written terms. East Coast Mechanical appears suited to local homeowners seeking HVAC repair, installation, or maintenance who value direct communication and documented service commitments.
“East Coast Mechanical of Boynton Beach are CROOKS!”
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.
