David Sacra
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.

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.

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.

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.

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.

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.
Jeff & Jenn Long
Tim D. Was Absolutely Amazing
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
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

Questions & Answers
How often should I have my heat pump inspected?
We recommend having a professional inspect your heat pump at least once a year, ideally before the heating or cooling season starts. Regular inspections help identify potential issues early and ensure the system operates efficiently.
How long does a heat pump repair take?
The time required for a heat pump repair depends on the issue's complexity. Many common repairs can be completed in a few hours. However, more extensive repairs might take longer. Your technician should be able to provide a time estimate after diagnosing the problem.
Will repairs affect my heat pump warranty?
Repairs by unauthorized technicians may void your warranty. Always use certified professionals familiar with your heat pump brand and model. Checking warranty terms before repairs can prevent unexpected issues and ensure coverage if available.
What maintenance can prevent heat pump repairs?
Regular maintenance can prevent breakdowns and costly repairs. Clean or change air filters every 1-3 months, ensure the outdoor unit is free from debris, and schedule a professional inspection at least once a year to check for wear and optimize performance.
