    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.

    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.

    I've had EFW perform work many times for me in Wellfleet. Show up on time, do good work, customer…read moreservice is good. They've done basic kitchen stuff, to more involved bathroom stuff and also installed a large generator while removing the old crappy one. They just did some work in outside shower - nice workmanship and good guys pretty much every time. Mike Katz in Wellfleet.

    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.

    They installed a new heating system that never worked right.The servicemen ruined out transformer…read more and thermostat. No parts in his van. I worked on heaters for years he definitely didn't know what he was doing according to Scott (who was extremely ignorant) when I told him I had an electrical contractor look at the system said they wired it wrong. Said we never touched any wires. So it must work magically then. Needless to say they charged us for what there service man ruined. The owner doesn't care either never received a call back. Scott said there on the same page. Now we have to hire someone to rewire it. The zone valves are jumped off each other so we have no heat in our bedrooms Would suggest you avoid hall oil I gave 1 star or I couldn't post I'd give it a negative stars if I could Rich

    If I could give zero stars I would, We had a new heating system installed by Hall Oil in March…read more2024, We called because we could not regulate the heat we would have the thermostat on 68 and it would get so hot so would have to run a fan, Called Hall and got Scott who is very rude and arrogant and he said if we come out and this is not our fault you will have to pay for the service call, We ended up not having them come out because it was a financial issue at that time, But this past November we had to have them come out because when we went to turn on the brand new heating system that they installed the screen keep reading stand by and no heat so we finally called again and got Scott once again and he sent a man out that could not barely speak English and could not tell us the issue but had no parts on his truck and was not eh telephone for the two hours he was at my house, and left saying sorry no heat. The next day same man came back told us it was the transformer and they did not have the part we would have to wait unto Monday. Monday morning I call and what do you know got Scott again and he said he can not send anyone out, That is when I lost it a little and he got a different man to come end of day and he said the wire was broken he replaced a thermostat and got the heat working in the main house but not in the bedrooms (two valve house separate heat but same system) He said we need to replace the valve head which we did......But we usually do not run the heat in the bedrooms unless it is very extremely cold like it has been this past week. So we go to try to turn the heat on in the bedrooms and guess what?!?!?!?!?! NO HEAT..... call Hall Oil and talk to Scott he said that they did not touch any wires and that we would have to pay for them to come out........Can you make this up? I spoke to a lovely women names Sara and she said she would have the owner call me back but I am still waiting. DO NOT RECOMMEND HALL OIL
