Best Boiler Services in Boston MA

Big Blue has been a constant rescuer to all the plumbing and heating issues we have had with an old construction house to a newer construction townhouse we are in now. We have used them exclusively since 2015. My children know every one (in the office and the team in the field) that's how many plumbing issues we've had. I'm happy to report that everything they've done has withstood years of use by adults and children. They have always been quick to respond. They found us a boiler fast in 0 degree weather, they've saved us from huge leaks from appliances and valves etc. Though they are popular they make time for their clients. Thank you Big Blue for all you do!

Ostroski Plumbing installed a new gas powered dryer for me.  They showed up on time and the job was completed to satisfaction.  Price was reasonable and quote was accurate.  Thanks!

Angel has been our plumber for over 3 years. I called him for the first time when I needed our dryer's gas line disconnected for repair. But, Angel's work ethic and his drive to do his best by his customers really shined through when we had to have our new washer and dryer installed. The space was tight, and the installation of the previous washer dryer was botched pretty bad. Angel and I had agreed on the price before he actually saw how bad it was. Even after discovering that the work was a lot more than anticipated, he did not back out of renegotiate. He and his brother worked diligently through the entire day, trying multiple things to make sure that the installation was safe and up to code (the previous installation, as it turns out, was not up to code). He even had to make multiple trips back to his garage to do some sheet metal work to reshape parts to make it fit the tight space.
Since then he has also worked on our replacing our refrigerator and dishwasher lines, and redoing the piping for the kitchen faucet. He has always made things much better than he found them.
He is amazing at his job, and he is definitely my go to plumber. I can't recommend him enough.

Received a return call from some rude lady to schedule a heating service. Worst attitude like they're the only plumbing company in MA. I'd rather not deal with that.

Great work and fairly priced. They got out to me next day. Sam gave me honest advice about my water heater and fixed all my issues. Will do business with them again and would recommend to anyone in their service area.

had them put in a new boiler and oil tank they did such a great job. I could not believe how quiet and efficient they were  they left the place cleaner than when they came. All workmanship was top notch and very professional .If you need service or a new boiler these are the people to call. Thanks to all the crew and the girl who called from their office you are the best

We've hired Andrew twice now, once to fix a clogged drain and once to replace a kitchen faucet. In both cases, he arrived within hours (he even got here an hour earlier than expected once... when does THAT ever happen?), did the work quickly, was very friendly, charged a fair price, and -- most importantly -- his repairs are holding up great. We highly recommend him and will definitely hire him again if and when the need arises!

When our water heater broke, they responded quickly and came on the same day. Welter was super nice and explained everything what was wrong and how to fix if the same thing happens next time. He never pushed / forced to buy or replace anything and gave us some options. We had a great experience with them and definitely we will use them whenever we need! Highly highly recommend!!!

Decided to get proactive with our 20 year old American Standard furnace. Selected Main Stream Mechanical to do the install and couldn't be happier. Technicians were very knowledgeable and professional. Very well run company with great communication. Couldn't be happier.

We recently called Simon for the first time to do some work at our house.  He called us back the same day and stopped by the house to see what needed to be done.  He scheduled and completed the work within a couple of days.  He was polite, gave us options, and explained everything as he did the work.  He didn't leave a mess and everything works fine now.  Simon is reliable and cares about his customers.  We had called other plumbers before we called him and they didn't even return our calls.  Simon was great and we would definitely recommend him to others.

Fairly standard job, changed out an old gas tank water heater for a new one. The main guy came over, took a look, gave me a no nonsense quote and said his guys could do it that day. Even threw in taking a look at my shower's plumbing because I mentioned the temp there was much lower than at the sink. The technician that came was great about showing me what he was doing with the shower so I could tweak it a bit more later if I needed to. Overall friendly experience and the price seemed competitive based on what I found. Been a few months now and no issues with the heater.

Bill did an exemplary job. He is extremely responsive, knowledgable, and a pleasure to work with. His customer service is second to none. He took excellent care of our furnace and addressed all of our concerns. I look forward to hiring him again in the future.

Yep, another 5 star review for Ryan.  He did some tricky re-plumbing for a new washing machine I installed at my place in the South End.  He was cool to work with, fast and thorough.  Also conservative - seemed like doing things in the way least likely to create problems for others in the building was important to him.  Thumbs up all around!

Charged $940 to hook up a dishwasher and attach an ice maker.  Feel the price was very high. They came to our home twice,  included in the charge was a transportation fee of $125 per visit that was not disclosed prior to scheduling.  We were taken advantage of and I warn others.  If the appliance dealer suggests a plumber go with who they recommend, we did not do that and regret our decision.

Fantastic service!  They went above and beyond to fix an issue I had installing a smart thermostat.  Rick was especially available, responsive and respectful.

Had the pleasure of having Ron come out and replace the shut offs on my washing machine. He was on time, courteous, used Covid precautions and was very professional . He was able to come by the very day I called them and was very reasonable with his pricing.
 I would definitely recommend them and look forward to working with them again in the future.

Irvin came as an emergency on call service for us. We had some questions and not only did he answer them, but he also took the time to fully explain how it all worked which gave us a peace of mind! He also explained it nicely in layman's terms! He met our expectations throughly and professionally. Truly appreciate his knowledge and service tonight; thanks again man 10/10 would request him again if it were possible!

You know all those horror stories you hear about plumbers who over-charge, or leave a mess, or do sloppy work? Forget all that, and hire Chase.  

The main case-iron waste pipe in my basement developed cracks in two places. Luckily the cracks were on top of the pipes so they weren't leaking yet.  I decided to have essentially all the cast-iron pipe replaced with PVC - about 30 feet in total. This was the thick, heavy, 5 iron pipe.  Not a small job.

Chase came and did a no-cost estimate.  I'd used them before for some small jobs so I trusted them and decided to have them bill me for time and materials instead of a fixed price.  They arrived on time, got right to work, and finished the job in 3 hours flat, including clean-up and testing all the new plumbing. The new plumbing is neat, clean and, well, perfect. And their price for the materials (all the new PVC pipe and fittings) was incredibly reasonable. I don't think I could have bought it for less on my own!  They cleaned up the basement thoroughly - sweeping and vacuuming.

As a homeowner, it gives me peace of mind to know that I can call Chase and know that they will do excellent work for a fair price.

the office lied to us about the cost of this job and was dishonest when we tried to fix the situation. Not interested in solid relationship, Too bad...

Avoid this company!!! I bought a heat pump from them They never told me they don't work when the temperature is below 30 degrees!!! Of course we had a week of sub freezing temperatures & it died!!! Also the kids installing it were about 17 years old!!! What a disappointment Avoid at all costs!!!
