What reviewers said

    I had a very disappointing experience with them. I was working with Gary Cyr on a geothermal project and was looking into a hybrid system. In the middle of a conversation he flew off the handle and hung up on me. Maybe he was having a bad day but I suspect he has a short fuse and may not respond well when a home owner makes suggestions or at all questions their work. They seem to be well respected but the lack of flexibility and basic business courtesy is a serious red flag for me.

    Sal answered all my questions, even the ones about water heaters etc. The system he recommended completely replaced my old propane heating system and keeps us cool in the summer as well. Installation crew was great to work with and did a great job handling a complicated installation.

    I highly recommend Southcoast Greenlight. Gary Cyr is extremely knowledgeable and great to work with. I looked at several companies before deciding on Southcoast Greenlight. They had the best offer, the most experience, and the best reputation. Gap Mountain Drilling out of NH did the drilling (also the best around) and Southcoast Greenlight installed the geothermal Climate Master system. Jon Cyr and Tim Tait installed the system quickly and efficiently in one week (ductwork already in place). They really know the system and did a fantastic job; both also great to work with. Jon is particularly

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Family owned

    “Southcoast Greenlight is the only family owned and operated company in MA and RI…”

Its website also mentions established, but not in a sentence we can quote cleanly.

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

Who Google shows alongside them

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
