I received a very pleasant call yesterday regarding my last service visit. I had a follow up visit…read moretoday and the entire system was rechecked. Riley did a great job! I now have the assurance that the system is ready for whatever weather comes our way. Thank you South Shore Plumbing and Heating.

Very poor experience!!! Had a new gas furnace and two heat pumps for heating and cooling installed…read morein our home on Cape Cod - over $30K expense. We had two water leaks in our basement and a flood in our attic that soaked the sheet rock so bad it looked like rain coming down in our upstairs hallway. Every time South Shore Heating and Cooling came to fix the problem we were told the floods were from faulty installation - a bolt wasn't tightened enough, insulation on the piping was missing or wasn't installed properly etc. Then most recently we found out the gas pipe they installed when they put in the new furnace was leaking gas! Just happened to find this out when National Grid came to swap out our meter. Lucky for us the National Grid technician checked the joints and found the leak. This leak was also from a bolt not being tightened enough. The amount of things that have gone wrong from poor quality of work is so upsetting and not once did a manager call to apologize. I was told by the nice woman that answers the phone that the manager doesn't speak with customers - I guess he doesn't care about their business either! The workers and receptionist were all nice to deal with but the installation and quality of work is very poor which to me means poor training and management. I will never recommend them to anyone and I don't have any peace of mind that the work that has been done is done correctly.

Wish there was a "zero stars" option…read more Terrible customer service. Rude & abusive staff from technicians to head of finance. I just got off the phone w/ that guy. They sent me a bill "120 days past due" for a preventative maintence contract I never established. His explanation was that the contract is w/ the address... not the owner...? How does an address start a contract.. & how, then, was the bill/acct in my name, if the contract was with the previous owner? He spoke over me the entire conversation. Could not get one full sentence out... then had the audacity, after I finally got a few words out to say ".. well, if you had just said that in the beginning..." Very rude, ignorant man. Previous incidents had left me frustrated, but I was a renter at the time & had no control over the choice of service provider. One tech showed up 2 hours AFTER the four hour window I had been given for the appt & then became verbally abusive with me bc I said it was too late & I was on my way out the door. I called the office & didn't even lodge any kind of complaint, just asked that that particular tech not be assigned to my address again. The woman said she would make a note on the acct. He was sent again, the following week. Laughed at me, when I expressed surprise he was there. When I called the office, the woman denied that anyone there would agree to such a note & didn't care about the poor treatment. Simply said techs are assigned according to the job & availability, period. Another tech appeared to have a psychotic break in my basement during a simple preventative maintence call (ordered by the previous owner). He was down there banging & clanging things, LOUDLY swearing & yelling at himself & the heating unit. I had told him on the way in that there was a 3rd shift worker sleeping in the house & asked him, to the best of his ability, to keep noise to a minimum. It sounded like he was fighting w/ someone & throwing things. I went down to inquire & he was spiraling out, literally tantruming. Said he broke a part & he'd have to come back. When he did, the same behavior continued. I was so concerned, I haven't allowed anyone from their company in my home since... & certainly never will again. When I've shared this w/ other community members, they say things like, "Yeah, they've really gone down hill." I've had dealings w/ them for over 15 years. I've never seen anything BUT poor service & performance... & deplorable customer relations across the board.

We hired EF Winslow for a tub to shower conversion. Took longer to schedule and complete than we…read morethought. They subcontracted shower doors to ClearvView glass. After a week or two a person named "Brandon" shows up. Brandon does terrible work, poor quality. He doesn't care about doing a good job. He doesn't fix mistakes. I have shower doors that don't hang straight. He came by to "fix" them. Now I still have crooked doors that don't glide smoothly; he made a new problem! AND now he blames EF Winslow fir buying poor quality doors. So do not use either companies

Buying a mini-split system is an incredibly difficult process. The Mass Save rebate system is very…read moredifficult to navigate. I got quotes and presentations from 4 different vendors and the pitch and price was exactly the same - hour long presentation and a $30k cost. However, what each vendor tells you is that IF you qualify a $10k rebate is available and your net cost is $20k. Essentially the rebate is a scam - it just gives contractors the ability to inflate the prices and use the rebate to make the system sound cheaper than it really is. I finally met with McIver and he was able to simplify the entire process. He is not a Mass Save contractor. So he does not work the rebate, just offers a strait-up cost to install the system. When he gave me his quote, I quickly figured out that Dan McIver was an honest man and that the whole Mass Rebate program was a scam. His quote with the similar equipment and the same number of mini-splits was $13,500. I hired him for the job and they started within a week. One of my biggest concerns was esthetics - I was worried about too many refrigeration lines running around the outside of the house. Our house is a rental property in Cape Cod that had a lot of charm to it and we did not want to ruin the integrity of it. Dan came up with a brilliant solution and was able to run most of the lines through the basement to minimize the lines on the outside of the house - we were so pleased with this solution. His team did a fantastic job building out the system - they were clean and finished the project on the timeline he quoted. The work was high quality!! Net is that Dan took a very complicated buying process and made it simple and affordable. He is highly recommended for the quality of his work, pricing and his honest and straightforward approach!
