Every pipe and piece of equipment is perfectly straight and inline. They made some suggestions and improvements which made this system nearly silent.

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
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.

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 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.
