Clean water is something you should be able to take for granted. It’s necessary for drinking, showering, and cooking. Unfortunately, the majority of water in Southern New Hampshire contains harmful chemicals, bacteria, and various contaminants. Are you sure the water from your tap is pure and healthy? An effective way to be confident in a clean supply of water is the installation of a water filtration system. Get in touch with MASI Plumbing, Heating & A/C at (603) 889-2331 for a free estimate, flat rate pricing, and trustworthy results.

Came home to my central a/c not working. After checking a few things, I called Masi Plumbing, based off of consumer reviews here. The person who answered the phone was accommodating to my needs and had a service person here super promptly! The service person was very friendly, highly informative and fixed the issue promptly- and not at a high cost either! Will def be calling them for our needs again, and referring them as well. Thanks a million Masi Plumbing!

My pipes froze and burst on a Sunday evening. I called several plumbers who would not give me the time of day. MASI Plumbing to the rescue! They sent a plumber (Nick) out immediately who was able to repair the broken pipes that evening, even though though he had already worked all day! A huge thank you! I highly recommend MASI Plumbing and will be using them exclusively in the future.

Bought a new boiler system from them this year and they gave us the most comprehensive quote for the right work (pointed out the need for fresh air and a new oil line which we knew were needed) at a good price. Unfortunately one of our parts in the system failed, but they had it replaced and our system up and running within 2 hours, and covered under warranty, so no cost to us. They have always been very friendly, down to earth, but professional. Great to work with!
