We offer turnkey solutions for both residential and commercial customers — no job is too large or complex for our expert team.

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

WE INSTALL BOILERS. And we do it well! Commercial & Residential services available for: Plumbing, Heating & Gasfitting, BOILERS, Radiant Heating, Water Heaters, Solar Heating, Kitchens & Bathrooms. We've been providing these services for a VERY LONG TIME and would love to provide our expertise and attention to detail with your next project. Give us a call today! P.S. I always return emails

"Ray quoted a replacement natural gas steam boiler at a price well under what both Boston Standard and Sila quoted me. Well under meaning close to 20% less. Ray is very responsive by phone and he shows up when he says is going to. Ray had done maintenance on our old boiler prior to this complete replacement. He actually performed maintenance on our old steam boiler, unlike when Boston Standard and Sila did maintenance they would simply turn it on and made sure it fired up. When Ray came and did maintenance after the 4 years we had both Boston Standard and Sila maintain our boiler he disassembled and cleaned out the incoming piping, replaced the glass water tube level, added a skimming drain, skimmed the boiler, etc. The prior 2 companies never did that level of work and it was in bad shape. In addition, not many technicians have knowledge of steam boilers these days even though they are still quite common in New England homes. Back to the new replacement boiler that we just had completed. Ray did a fantastic job on the installation. I really couldn't ask for better service. He was timely and efficient (we had our heat back on the same day), explained everything thoroughly (usually multiple times for my benefit) and has called and come back to check on everything a couple times since the installation. He's really gone above and beyond. We have 1-pipe steam radiators and he understands the intricacy of steam quite well. Ray also did all the plumbing when we had our kitchen renovated. He was our contractor's choice for a plumber (which is how we found Ray) which gave him that extra credibility knowing other professionals use his services. I would not hesitate to use Ray again in the future and recommend him to everyone."

"Frances is pleasant to talk with and was punctual and responsive. My problem was that he's probably too busy. When I received his invoice, he charged me for the recessed lights that *I* had already purchased and then I had to prove myself by showing him the receipt. He charged me 2x the Home Depot price for Romex (which I had 100 feet of in my garage, ready to go). He put in dimmer switches that didn't match the coloring of my house project (old switches were almond, new switches should have been white) and then indicated he thought I wanted almond color since those were in other places (so were the white!). He should have asked what color I wanted, but didn't and then didn't offer to replace them. This experience left a bad taste in my mouth, I'd not hire him again."

"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."

Water Heaters questions, answered by experts

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

Standard electric water heaters (about 40 gallons) typically need a 30-amp circuit breaker. But if you have a newer model, a tankless water heater, or one that’s more energy efficient, you’ll likely need a higher amperage to power it. 

Having the right size circuit breaker for your water heater is an important part of making sure it heats water efficiently and runs safely. A licensed electrician can help you navigate your options, and determine what you need for your new water heater.
