Main Stream Mechanical

Huge shout out to the crew at Main Stream Mechanical. Eric came out, reviewed my current system, and gave me his recommendation for replacing my furnace and hot water heater with a new, energy efficient furnace/hot water heater. Brenda, as always, was a pleasure to deal with. Answered all my emails and calls promptly and gave me all the information I needed in a timely manner. She even went out of her way to register my new furnace and provide me with all the information I needed to apply for my rebate! Nick and Marcus did a great job installing my new furnace/hot water heater. Both were very friendly and professional. Nick answered all my questions, gave me a “tutorial” on the emergency shut off procedure for my new furnace, and did a fantastic job re-plumbing all the lines needed for the install. I highly recommend Main Stream Mechanical for all your HVAC needs.

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.

We chose them because they are reliable and professional. They are willing to answer questions and are very cooperative with scheduling work to be done. They are certified to work with Mass Save. In addition, when we experienced a heating issue, we spoke with one of the contractors who helped us build our addition... he gave us their name and recommended them as honest and trustworthy. We are satisfied with the positive relationship and appreciate their help when needed. We would not hesitate to recommend Main Stream Mechanical Services.

Joe was prompt (earlier than scheduled, but he checked first to make sure it was okay). He and his helper got right down to business - efficient but responsive to my several questions. Eventually I'll need to replace the toilet, and Joe was good about explaining the options and making a recommendation. I've been doing business with this company for at least 15 years and never been disappointed; it's my go-to company for all my plumbing and heating needs.

From quote to installation the process was efficient and professional. Price was competitive for a top brand name boiler. Jim and his install team did an outstanding and very clean job.

My husband resolved the problem after I spoke to the plumber. I was impressed that I received a call quickly and the plumber was very polite and friendly. I would call them again if we have a plumbing problem.

I called to find out information on hot water heater options and they were able to move my appointment up a day. Jim, the lead technician, explained about the various options and provided some great technical recommendations. They were punctual, extremely knowledgeable, polite, and efficient. I would definitely hire them again.

When you are used to settling for average or even poor service, it is nice to know that there are still companies like Main Stream Mechanical that excel at what they do. From the first contact to following up on the results, MSM promised and delivered. Their techs were prompt and thorough, explained the process and made sure that all systems were functioning properly before departing. Brenda was nothing short of spectacular in her communication and ability to get HVAC techs and electricians to us when convenient and promised. I could not give them a higher recommendation and hope they will be there if ever needed again down the road.

It went smoothly and professionally, and since I was not the original owner of the house, they were kind enough to walk me through the house's septic system an educate me as to its layout. They were not only professional but very friendly and willing to spend time accommodating my ignorance.

Our furnace had been intermittently failing to ignite for months. Tried three different contractors and none could figure out the problem. One replaced the pressure switch ($200). Another replaced the inducer ($450) and then it failed to light a few days later. They came back ($150 service call) and just shrugged and said we need a new furnace. Quoted $12K for it. I laughed and told them I'd look elsewhere. Problem went away for a couple months and then, of course, stopped working during a really bad cold snap. Had yet another contractor come out who managed to get is started but then it stopped running later that day. The next day I called Mainstream and they said they were very busy but would call back. Several hours later they called and I told the tech (owner?) the symptoms. I'm somewhat knowledgable about mechanical things and told him that I tested the pressure switch, checked the vent and that the furnace was able to start with the firebox cover removed. He said "the intake vent is blocked, I guarantee it". I told him I looked inside the vent and he said "then it's blocked somewhere where you can't see it". He said that often times leaves get sucked in and are trapped by a small screen right at the furnace entrance. While I had him on the phone I removed the intake pipe and sure enough there were some leaves in there. Cleaned out the leaves and the system fired right up. I've spent over one thousand dollars over the last few months trying to get this problem sorted out and this guy figured it out over the phone. Told him he just earned a customer for life. Most of the HVAC contractors around here are either incompetent, dishonest or both. Mainstream is the real deal.

came right away.. needed a part.. got it running until the part came in very quick service very professional would call the again

Excellent, the two gentlemen showed up early in the time window I was given. I showed them my two problems and they repaired both in under an hour. It had rained the night before and the ground was still wet, and whenever came into the house they woild stop and put protective coverings on their shoes to protect my floors, I appreciated that simple courtesy.

Crew was fast, clean and professional. Had some minor issues with the install but they were extremely responsive and quick to fix the issues.

We were vey happy with the work and professionalism! Would definitely recommend Main Stream Mechanical.

Excellent advice. Very professional.

I was very pleased with the services provided by Main Stream Mechanical. I worked with the owner to find the right type of equipment for my home and he came to work with the installation team on the second day of installation. I had many questions as the purchase comes with a big price tag and I was nervous about making sure I was making the right decision. The team at Main Stream was very patient with all of my questions, working through all of the numbers and various scenarios to find the right solution for my home. The installation team was very efficient, showed up early, worked all day and was very professional. I would recommend Main Stream Mechanical as they were honest, very knowledgeable, helpful, and professional.

Had a very good experience. Owner aggressively resolved some scheduling issues with the local gas utility. Worked hard to explore the various heating options. Gave sound and honest advice.

They said the units were functioning as expected given the life of the furnaces. I gave price a C because there really wasn't any work done and nothing to be cleaned. $289 seemed like a lot for a quick inspection. Eric was punctual and seemed to know his trade well.

I am *extremely* impressed with their operation. Knew all the details of the Mass Save HEAT Loan program and rebate process and helped out with that immensely. Not only that, but both Eric (the owner and lead technician) and the office manager Brenda are both VERY responsive to questions. I was always in the loop about scheduling and they came when they said they would. The technicians who came were very nice and courteous and were patient with my many questions. I was also impressed that the owner, Eric, was there to inspect all along the way. We are very satisfied with the system they installed and have been enjoying our new AC! I will definitely be using them again. Also, it's worth noting that you do pay a little for this level of service. We got 4 estimates done and Main Stream was the 2nd highest estimate. However, it was worth the extra money to have things done so well.

Excellent service. I had alot of questions because our tank is in a smaller space and Brenda was wonderful about getting me answers and even had the owner call me. I really appreciated them taking the extra time to help me make sure we were selecting the right size tank. Jim arrived and drained the tank, removed it, and installed a new hot water heater. He answered all my questions.

His price was a bit lower than the first one I received but right in the same ball park. When the third estimate came in - it was substantially lower than the first two and I decided to go with that contractor instead. I have no doubt that Main Stream Mechanical would do a superb job but this one came down to money. ( And the contractor I choose was recommended by a co-worker who spoke very highly of his work.) Eric was very professional and very knowledgeable about what needed to be done.

I had read their other reviews on Angie's List and they were very favorable so I opted to contact them in the late spring for a quote to preform this work. I'm happy I did. Eric was very methodical in his approach and outlined what I needed and the process of how getting a gas line run from the street to our house. I was interested to find out that that the oil burner I had was too big for my house and Eric believed this was part of the issue with large amount of oil consumption i experienced each year. In any case, we went ahead with the plans within a few weeks of his visit. Getting on the list to have National Grid run the gas line took the longest amount of time but with the help of the Main Steam office manager, Brenda Castonguay, I went through the process to get this installed. In early June the oil boiler was removed and the new boiler installed. The piping above the new boiler looks like a piece of artwork! In addition, the old oil tank and all of the remaining oil was removed at the same time. The job was neat and the crew cleaned up everything after they left. If you're thinking of this conversion, I would recommend giving them a call. Quality work at a fair price. We could not be happier.

Main Stream's technicians were right on time for my appointment. Jay and Brandon were both informative and professional. I would trust them to come back and provide their services again in the future. I am very happy with my experience and would highly recommend this company to anybody else I know in need of their services.

The Main Stream team helped me through the entire process of converting from oil to natural gas heat - and when I say entire, I mean ENTIRE! They guided me through the MassSave 0% loan process, explained the different systems and options available, provided scripts and guidance for interacting with various utility companies, handled all of the scheduling and finally installed a full system in just over a day. I've never worked with a provider that has made what could be a confusing and time consuming process so smooth and easy. In short, the Main Stream team made converting from oil to natural gas a surprisingly smooth experience. While there is a slight premium for their service (about $500-$1000 in this case), their expertise, guidance and ability to make everything easy is very well worth it.

They fixed the issue (no heat)promptly and it has been working properly over the past year.
