Absolutely fantastic HVAC install
Dustin and his co-worker did an absolutely fantastic job installing our brand new HVAC system. From start to finish, he kept me apprised of what was happening and any changes or upgrades that needed to be made. There were no surprises or issues. I cannot recommend Monomoy Mechanical and Dustin highly enough. In fact, I’ve already asked the company to look at another small project.

The entire team is phenomenal
Richardo, Matt, the entire team is phenomenal. I feel so fortunate to have found Matt and his team. They are trustworthy, responsive, very talented, and experts at their craft. On this occasion, they came out on a weekend in the pouring rain to fix an issue with an outdoor shower. They could have pushed it to a sunny, warm, dry day but instead just came out on a cold, rainy, windy spring day to address and resolve an issue my landscaper had discovered just a few days prior. It's comforting to know I have a great team that I can rely on. If you need an HVAC/plumbing mechanical company anywhere near on/off the Cape, these are the guys. Now to just try to persuade them to come to my primary residence outside of Boston.
Jeffrey Katz
Excellent Experience and Quick Response
I called my (old) HVAC company for repair of my on-demand hot water system. They have an AI assistant instead of a human who answers calls. The earliest appointment was two weeks out. The AI assistant reassured me that I was a "preferred customer," but wasn't able to schedule anything sooner.
I then called Monomoy Mechanical and spoke with Matt in the office, who understood the issue, reviewed the techs' locations and schedules, and scheduled an appointment for later that afternoon. Tim, the tech who came out, was experienced, knowledgeable, and an excellent communicator. He quickly diagnosed the issue. A part was in stock at the shop, and the repair was completed two days later. As a new customer, I was impressed by the quick response and professionalism of Matt and Tim. This was an excellent experience from the first call to having hot water again.
Peter Hussey
Very friendly and knowledgeable
Tim was very friendly and knowledgeable, able to explain the problem with my water heater in terms I could understand.
Dorothy Gibson
On time, knowledgeable, and considerate
Matt was on time, knowledgeable, and considerate. He was willing to work on a boiler no one else could bother with. I greatly appreciated his time and assistance.
Kim Gagliardi
Excellent service and a fine man
Thank you. Excellent service and a fine man. Mat reviewed all concerns; he made all necessary repairs and reviewed all fixtures in both bathrooms to ensure there were no hidden mishaps. I am so relieved. No need to ever look for a new plumber. Thank you, thank you.
Marjorie Mclaughlin
One of the Nicest Plumbing and Heating Company
Fantastic! Probably one of the nicest plumbing and heating company I’ve worked with. I maintain four houses in Chatham and he is by far the easiest person to work with. I would highly recommend him to anyone.

Couldn't Have Asked for a More Fluid Experience.
David was great, super knowledgeable, super courteous, friendly, direct, and skilled. Couldn't have asked for a more fluid experience. Also, the gentleman who came out to assess initially—I believe it was Matt, but I'm not certain—and the young lady I spoke to on the phone all demonstrated cohesive teammanship and a mutual understanding of my issue, all with shared dedication to attack and solve the problem, which could not have been done in a better fashion. Thank you, guys.

If you have this issue, Call Monomoy!
Matt came on short notice to pressurize a 10-year-old Rinnai boiler that had stopped working. He knew immediately what to do and even showed me how to correct the problem the next time it occurs. Photo is of boiler issue before repair. If you have this issue, call Monomoy!

Cleanup after was immaculate
They were able to send Ricardo on the same day as my call about a toilet leak seeping downstairs. Rico was efficient and thorough. He called in a second person for the last part of the work so one could be upstairs and one below. Cleanup afterward was immaculate and invoice was very reasonable.
Barbara Prindle-Eaton

Jacky Penswick
Can't Go Wrong with Local Professionals
Matt and Dave replaced a failing boiler in our home. They provided great recommendations for what brand to get for reliability and warranty (Ideal). They did a great job and had a very good price. Was impressed with communication from start to finish and how quickly they got us on their schedule as we kept applying band-aids to our failing unit. The installation was completed in one day and looks great. Don't think you can go wrong with these local professionals. Thanks Monomoy Mech.

Monomoy Mechanical is the home plumbing and HVAC company you’ve been looking for
This was a replacement boiler in the never-ending chase for energy efficiency. The installation was amazingly fast. You’d think Dave and Matt were mechanical engineers. Every pipe and piece of equipment is perfectly straight and in line. They made some suggestions and improvements which made this system nearly silent. The heat output is incredibly fast. Way faster than our previous boiler. Now we can shower, run the dishwasher, and do a load of hot wash laundry and not run out of hot water in the shower! When the work was completed, you could have eaten off the floor it was so clean. Honestly, Monomoy Mechanical is the home plumbing and HVAC company you’ve been looking for: smart, intelligent mechanical work and at a reasonable price—installed and cared for by perfectionists.

Super Happy With the Customer Service
Super happy with the customer service, installation, and fair pricing experience we had with Monomoy. After the installation took far less time than expected, they actually lowered the price for me, even though I had already accepted their initial proposal, signed the contract, and paid half the deposit. I will definitely use them for all my HVAC needs going forward! Brewster, MA
