"Great service by ADT! Integrated with Google. Officially have a smart home!"

"I’d love to leave a 0 star review if I could. The level of disorganization and miscommunication with this company has been staggering. Their customer service is garbage. Don’t waste your time, money, or energy on this company. False promises and sub-par work across the board. We will gladly take our business elsewhere in the future. We had an initial consultation with someone named Darren for a heat pump/furnace replacement. We also lumped in a sub-panel install & dryer replacement. Darren assured us that everything would go smoothly, all the work would get done over the next week. The HVAC & electrical teams showed up several days earlier than expected, which sounds great in theory, but required us to take an unexpected day off work. The wiring they ran to the thermostat was installed hap-hazardly and now just dangles off the HVAC plumbing. The electrical team installed the sub-panel, but installed it too close to our irrigation control box. Now we can’t open the door to the irrigation control box. The electrical team also installed an outlet for the new dryer in a location we wanted, but left the rest for a plumber to finish. When the plumber showed up a week later, he said the dryer could not be installed in that location. He then tried to charge us for additional work that we already had paid for in our initial contract with Darren. (He did actually charge us to cap the gas line to the old dryer). Multiple teams also told us they would haul away our old dryer. That never happened. On top of everything else, we were told (multiple times by Darren and the HVAC team) that, as a part of our 3 year maintenance plan, they would come back quarterly to install a new filter on the furnace. When we called about that today, we were told “that’s not a service we’ve ever offered.” The customer service is absolute garbage. We already feel cheated out of the money the plumber charged us. You’d think after all this, the least they could do is toss in a few filters. We’ll never use this company again. I’d caution anyone else to get EVERYTHING written out in detail before you do business with this company. Better yet, just go to someone else."

"They were fantastic! Start to finish they were great on time and on budget!"

"Great work!"

"Jonathan installed breakers and 50A outlets in my garage for car charging. He has very reasonable pricing (obtained multiple quotes), and he completed the job efficiently while addressing many requests. He is a contractor who responds quickly, even after the initial payment!"

"Professional service with exceptional care. The communication from start to finish was top notch. I will be hiring this team for all electrical needs for my home."

"Zach exemplifies the true qualities of a tradesmen, a service change in the middle of winter with snow beneath your feet did not seem easy. But he got it done quickly and the work looked even better. I would recommend Zach to any one of my peers or friends. Thank you again and be careful up on that ladder!"

"I hired Merrimack Valley Plumbing to install a boiler in my home, and my experience was overwhelmingly disappointing. While the boiler functions, the installation process and quality of work raised numerous red flags. I want to share my experience to help others make an informed decision when considering this company. Installation Issues Code Violations: The exhaust is less than 3 feet from the gas meter, and the holes drilled in the joists for intake and exhaust are less than 2 inches from the bottom, both of which do not meet code requirements. Improper Venting: Both the exhaust and intake vents are installed too close to the ground (not meeting the 12-inch clearance required for expected snowfall) and are too close to each other (less than the 12-inch separation required). Unsealed Penetration: The hole drilled in the siding was left unsealed, creating a potential entry point for rodents. Condensate Drain Issues: The installed condensate pump is leaking and wasn’t tested. Additionally, rather than a permanent drain installation, they daisy-chained it into a pump for a portable air conditioner. Wiring Errors: The zones for the primary bedroom and second floor were wired backward, causing overheating in both areas. Missing Outdoor Sensor: The outdoor temperature sensor, critical for proper operation, was not installed. No CO Alarm: A carbon monoxide alarm was not installed, which is essential for safety. Unprofessional Workmanship: Trash, including a metal duct pipe, was left in the crawl space near live electrical wires. Process Concerns Permit Delays: The company failed to file permits before starting work. I only discovered this after contacting the town permitting office myself. Mismanagement and Delays: The project stretched far beyond the promised timeline, with repeated excuses about missing parts and limited crew availability, despite prior assurances that the job would be completed in two days. Broken Promises: They claimed a project manager would take measurements in advance to ensure a smooth installation, but no one came. Additionally, they rescheduled initially, promising a larger crew, only to send a single plumber on the first day. Misinformation and Deception Throughout the project, I encountered multiple instances where Merrimack Valley Plumbing provided misleading or false information: - They lied about the dates permits were filed. - They claimed delivery issues caused delays, though they should have anticipated these based on the advance photos provided. - They repeatedly shifted blame rather than taking accountability for the delays and issues. Overall Experience While the boiler itself works, the installation was riddled with code violations, safety oversights, and poor workmanship. Additionally, the company’s lack of transparency and repeated dishonesty made an already frustrating situation worse. I would not recommend Merrimack Valley Plumbing to others. Their lack of professionalism, disregard for safety codes, and failure to take responsibility for their mistakes created an unnecessarily stressful and costly experience."

"Scott did an excellent job for us. We needed an EV charger installed and a few other things done. He came by, sized up the job and gave us an estimate. In a few days he showed up ready work. He installed the EV charger, re[laced 4 thrmostats, and fixed a doorbell. All went well. His price was reasonable. He worked quickly and efficiently and got everytjing right the first time. I highly recommenr Moses Electric and would glady hire Scott for future electrical jobs."
