Recommended Customer Reviews
Jo No N.Main Stream is very helpful, answers all my questions, and accommodates my work schedule for service and maintenance.
Kate R.These guys were absolutely amazing! Just had a new high efficiency boiler and super store water heater installed by Eric and his team of experts and I can not be happier!! They were punctual (10 minutes early, actually), SUPER clean, and 110% professional! Eric had the estimate completed and returned to me in less than 48 hours and had the job scheduled within a few weeks time. The job took exactly the amount of time they predicted and they were so helpful in getting all the paperwork completed to help me get my rebates through Mass Save. Everything was done ""by the book"". Finding a reliable contractor of any sort is nearly impossible these days but I feel like I hit the jackpot with MSM! I felt 100% confident with them working in my home, even if I had to step out for a bit, leaving them to ""do their thing"". I would highly recommend Main Stream Mechanical to anyone looking to upgrade their heating system. In fact, I will be calling Main Stream this spring to service my central air. If you're shopping around for a company to service your heating or AC or looking to upgrade your system, look no further than Main Stream! You won't be disappointed! HIGHLY RECOMMEND THESE GUYS!!!
Lisa M.we had an oil burner service company for 20 years and the owner retired a few years ago. we thought we would never find that level of service again. we decided to convert to natural gas, and we used mainstream mechanical. we also installed a whole house generator. these guys do great work, are professional, and know their stuff! we are always assured that no matter what time of the year, day or night, if we have a problem they are there! we highly recommend mainstream. Lisa and Richard M.
