  In April of 2018, I had Mainstream Mechanical get an older Weil McLain boiler running. The guys came and took one look at it and said it should just be replaced. I didn't have the money at the time so just asked them to get it running again. The expansion tank was very rusty and questionable looking but they didn't replace it. I spent over $1,300 dollars to get it running and within 2 days, had the expansion tank break, causing 3" of hot water to flood the entire basement. Thankfully the brand new well pump was up on cinder blocks barely above the water. I spent hours bucketing water out of the basement and pulling down wet (from the steam) insulation and throwing it all out. Called Mainstream back and they said basically it wasn't their fault or problem as they didn't replace the tank. I understood that but said just by looking at that tank, it would have been a good idea to have replaced it. I spoke with the owner and he finally agreed to come out and at least put a new expansion tank on the boiler at no charge. They also gave me an estimate of over $6,500 to replace the boiler. Follow up...less than a year later in 2019, I had to replace this expansion tank again and had Mike Poole do it. In the summer of 2020, I did finally replace the boiler, even though it was still working okay but it was over 20 years old and had a lot of rust and I was worried about having to dump more money into it. I ended up having a new Weil McLain boiler system put in by Four Season's for $5,500! I did had Poole quote it but it wasn't cast iron and would have cost about $7k. I would NEVER use Mainstream Mechanical ever again. They are expensive and in my experience, did the bare minimum to get a system functioning and weren't very sympathetic or apologetic regarding the expansion tank and basement flooding read less

  It went very well. The work was done over a couple of weeks. The workers were very polite and able to answer my questions. They were neat and cleaned up before they left each day.

  This is the MOST awful experience I had in 20 years with home maintenance companies. 99% of reviews here are FAKE! Check the profiles of all the 5 stars reviews - they are closed profiles, all of them! Unfortunately I just learned about it while they were here. Called them for air duct cleaning through the whole house. They made a hole in my duct work stuck a regular small shop vacuum in it and "ensured" me that it will suck the dust from ALL 15 vents in the house. As he was about to leave, I noticed that air returns are dirty exactly how they were and pointed it out. ATTENTION! He takes out a dirty chimney brush and furiously sticks back and fourth into the air return in attempt to clean the dust. This is a pure health alert and I think this "business" must be closed down forever. I will follow up with BBB and other organizations on this... As I understood that I was simply scammed. I told him to stop all the work and leave. Paid him half of what was agreed on and he left leaving all the mess that I ended up cleaning for another hour. They are NOT a professional air duct cleaning company, but just people who bought fake "great" reviews and scamming people with a ladder, chimney brush and a vacuum cleaner. This is what real/professional duct cleaning service must look like: [*** Link removed *** read less

  We own a home in Gloucester that we rent out during the high season. During the hottest week of the summer, two of our central A/C units broke down and we needed to replace them fast. I called ten different A/C companies on a Sunday night—and was amazed that I reached SEASHORE COMFORT SOLUTIONS directly. Sarah sent out someone from their team the next day to do a diagnostic; we ended up replacing the two units within days of that first visit. Every time I called the office, someone answered. Every time I wrote to SEASHORE COMFORT SOLUTIONS, I received quick responses, clear answers and very courteous service. They deserve FIVE STARS every time. When the units were installed, the tech called me about the wall mount placement and then again to tell me they were leaving. SEASHORE COMFORT SOLUTIONS was so easy to work with and I'm relieved to know that they are nearby and ready to help when needed. Thank you to Sarah, Rich, Frank and everyone on the SEASHORE COMFORT SOLUTIONS team! read less
