On time, knowledgeable, and considerate Apr 23, 2026

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.

If you have this issue, Call Monomoy! May 27, 2025

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!

Can't Go Wrong with Local Professionals Nov 23, 2023

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 Nov 2, 2023

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.

Excellent service and a fine man Apr 9, 2026

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.

One of the Nicest Plumbing and Heating Company Jan 8, 2026

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. Nov 25, 2025

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.

Fast Response and Effective Solution May 22, 2025

My hot water wasn’t working, and they came out within 4 hours of me calling. The tech diagnosed the issue as an electrical one with a faulty switch. He was able to bypass the switch, and we are all set in under an hour!

Cleanup after was immaculate May 20, 2025

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.

Tim D. Was Absolutely Amazing May 7, 2026

Tim D. was absolutely amazing. He went above and beyond to address the issue I was having with a newly installed thermostat. He was patient and gave thorough step-by-step instructions for the thermostat as well as the app that goes with it. I would have Tim back for any repair in a heartbeat. Monomoy is lucky to have Tim representing their company. Well done, Tim!

We Are Very Pleased With the Install Apr 21, 2026

We recently had a Fujitsu mini-split system installed by Monomoy Mechanical of Yarmouth, MA, and we are very pleased with the install and performance of the Fujitsu equipment. Jason Houle was our contact from beginning to end. Jason was extremely helpful in the process, he answered all of our questions and was able to arrange the install on a day we had asked for. Dustin and Dave were the installers and made short work of the job. They were able to work the line set through the attic as we asked and were very considerate of protecting our floors by laying down drop cloths and cleaned up as they worked from room to room. Once the job was done they walked me through the functionality of the system, the do's and don'ts, and the things to look out for. We had reached out to 3 other companies in and around the Dennisport area for quotes and that's mostly what we got, just quotes. Monomoy was really great in answering any questions about pros and cons before we had even put down a deposit and when you call the company, there was a person that actually answers the phone and she was very polite and helpful. If you find yourself looking to have your heating and cooling needs met, I would strongly recommend reaching out to this great team. Sincerely, John

Amazing! Three Days After the Storm Feb 27, 2026

Amazing! Three days after the storm, we finally got our power back only to realize the heat didn’t come back on. Called Monomoy Mechanical. Within 45 minutes of our call, we had a technician at our house assessing the problem. Matthew left to get the part needed and was back within 45 minutes. Within a 2 hour period we went from no power to power, no heat to heat! We would highly recommend this company, they were speedy, professional and truly understood our frustration.
