MASI Plumbing, Heating & AC

I am remodeling and doing upgrades to my childhood home and it was time to replace the 40 year old natural gas boiler and 25+ year old hot water tank. Back when the boiler was installed it only had a efficiency of 67%+-. As you can imagine after working hard in all these New Hampshire Winters throughout the years I'm sure the efficiency has dropped dramatically(as I could tell by my energy bills). I knew I was on borrowed time with both these units and figured lets get this done during the Summer before the worst would happen during the Winter. As most people in Southern NH knows MASI's has been here for a long time(over 60 years)and is a family run business. Being a business owner myself I know that customer service is a key part to business. Anyone can sell you product, but it's the

Bobby Boisvert and his team saved the day! The Grand Opening and launch of our new hardwood flooring wholesale distribution center in Hudson, New Hampshire landed on an amazingly hot streak of weather. Bobby and his crew got in here early. Got the work done well and promptly, then tested the system over the next couple days and everyone was comfortable and impressed with our new location. Couldn’t have done it without MASI- Steve Diggins, Operations Manager, Specialty Forest Products, Hudson, NH

We have used MASI for multiple projects in our house. Most recently, they replaced our old steam heating system with a hydronic system, and remodeled a bathroom. The staff are always very professional and communicative. I am never left wondering if they are going to show up on a given day. Highly recommended!

Masi Plumbing did a wonderful install of a hybrid HVAC system replacing old inefficient equipment. The install team headed up by Doug was extremely professional and courteous. Their work was clean and accomplished with much care. We appreciated that at the end of each day they reviewed the work they completed and explained what the next days goals would be. We highly recommend Masi for anyone considering updating their HVAC system.

We manage 83 apartments in Nashua so we regularly need quality work done in a short time frame and at a good price. Masi delivers on all three of those areas. They can do it all, including Boilers, water heaters, bathroom remodels, mini-splits, plumbing repairs and more. We couldn’t recommend them more!
