Main Stream Mechanical Inc

I had a plumbing issue that could have turned into a real nightmare, real quick. I contacted John and he set me up with someone who came out and stopped a leak almost immediately and probably saved my ceiling. The price was incredibly reasonable also. Fast forward a couple months my mini split system stopped working so I reached out to John again and within days they had come out, diagnosed the problem, ordered the parts, and repaired the entire system. Couldn't give any higher praise to this business if I tried, they're super fast, highly efficient, and everyone who works for them are genuinely nice people.

The office staff is friendly and helpful, and the technicians always throughly explain their findings and answer any questions I may have. Great service! Service: Heating system repair

The serviceman was efficient and tidy. He performed the yearly maintenance service on our heating system and answered our questions in detail. Great work. Service: Heating system maintenance

I had a great experience with Main Stream Mechanical with our removal of our old oil boiler and installation of our new gas boiler and water tank. Eric was great in providing all of the information needed when he came to provide a quote and answered all my questions. We had to deal with National Grid to get a new gas line, account, and MassSave loan, and though National Grid was a little difficult to work with, Main Stream Mechanical was amazing and very accommodating to National Grid's ever moving schedule.

When National Grid finally had the gas line installed Main Stream's team lead by Nick was professional, courteous and just all around great. They removed all the old oil boiler and installed everything within a few days and cleaned up as if they were never there. Our experience went very well with Main Stream Mechanical and we'll be surely using them in the future!

I have used Main Stream for the past 8 years in two different homes. They are responsive, professional, knowledgable, and thorough. I use them for all of my heating, air conditioning and general plumbing needs. Services: A/C system repair, A/C system maintenance, Heating system maintenance

Mainstream Mechanical performed repairs on my central AC system and also on my tankless heat and hot water system. Every touch point from making the appointments to having their Technicians in our home was simple and very pleasant. The entire staff is professional, pleasant and highly efficient. It was a pleasure to do business with them and I would highly them to everyone.

Great service from the start. Erik came to my house to provide information about the product. He was very knowledgeable, and answered all my questions. Technicians did a great job in the installation, keeping me updated on the progress as I was working at home. They even braved the April nor'easter storm, to get as much done before it was unsafe to be up on a ladder. Nick took the time to explain how the system worked when all was complete. Very happy with the job!

Our experience with Mainstream began with a request for pricing to change from oil to gas and AC. Eric (Mainstream) was the only vendor who both gave us the feeling of being a partner in the bid discussions and also, who knew what he was doing. Over the years we are satisfied with both the quality of the product installed and the service provided. We indeed recommend Main Stream.

I was dreading having my nearly 20-year-old gas furnace replaced but Main Stream Mechanical made it easy and painless. I was able to use Mass Save's HEAT Loan and furnace rebate program and Brenda helped me learn what to expect, and she was super communicative about scheduling and the entire furnace replacement process. The technicians who did the replacement were all polite and respectful. Overall, this was a great experience and I definitely recommend Main Stream Mechanical.

I have had nothing but positive experiences with Main Stream Mechanical. I found them originally on Angie's List and was impressed with the number and breadth of positive reviews. I have had them service my boiler and heat pump and both times the process was exceptional. From the administrative staff who answer the phones and help with the scheduling to the service providers themselves, everyone was incredibly kind, knowledgeable and professional. They will undoubtedly have my business for years to come.
