Two DaSilva Mechanical customers had been told by another company that their air conditioning needed replacing, and both say Jonathan got it running again instead. The Middleboro, Massachusetts HVAC company does oil and gas heating, air conditioning and specialty HVAC repair, installation and maintenance across the South Shore. It holds 5★ from 205 ratings on Google, 5.0★ from 16 ratings on Angi and HomeAdvisor, and an A+ from BBB. In a June 2026 Google review, a customer who had called for a replacement estimate on an AC condenser another company had written off said Jonathan had it running within a few minutes, then came back for a full tune-up. An August 2024 customer, told by another contractor that their AC needed replacing, said Jonathan found and fixed a leak in the compressor. A June 2026 reviewer said a boiler clicking problem that a previous company could not figure out was diagnosed in about five minutes. The installations run from a September 2026 job replacing a 1980s system with a Lennox 5 ton air handler and condenser to a 96% efficient natural gas furnace in September 2025 and a furnace with upgraded gas pipes in December 2025. A May 2026 customer getting a new mini split said the quote listed everything from A to Z and the crew left absolutely no mess. In July 2026, a customer wrote that the crew even got a long lost diamond ring out of a vent. BBB lists gas fitter licence GF 5236, licence 206049 with the Office of Consumer Affairs and Business Regulation, and BU-320250 with the Department of Fire Services.
Highly reccomended! Quick response time and fair pricing. They did a thourough check of my system and had me back up and running in record time.
I highly recommend Jonathan and his company for all of your hvac services. He and his crew replaced an entire air handler and condenser and did a phenomenal job. I went from a 1980’s unit to a top of the line Lennox 5 ton unit that runs amazing. He took the time to answer all of our questions and did a great job from start to finish. I look forward to working with you guys in the future. Thank you!!
Jon is always communicative, honest, and reliable. He replaced a mini split unit for us today. I appreciated the time he took to speak with me about our options, and how diligent and through he was today.
Jonathan is always professional and courteous and does fantastic work. I've hired him four or five times now for various jobs. I'm always happy with the work he does and the price is always fair. I rarely post reviews for contractors, but I felt compelled to finally give this man his due. He's earned it with all the good work he's done for me. You won't regret calling DaSilva Mechanical. Thanks again, Jonathan.
I appreciate Da Silva's courteous manner and competitive prices. Highly recommend.
