"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."

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"Very well, above and beyond the call of duty."

"I reached out to couple of companies and ultimately decided to go with NETR, and I’m glad I did. From the salesman Chip, to the installer Daniel Rodriguez, their professionalism was exceptional. Their work ethic and attention to detail sets them apart from other companies in this business. Daniel is an expert and went above and beyond to make sure everything was tidy and perfect! They’re really invested in customer satisfaction!"

"The work was done correctly and promptly, but quite expensive. On the plus side, he presented all the options and didn't really try to upsell. Just the facts."

"Found this company from someone's recommendation, now really bad recommendation! Anyway, had sinks backing up - something plugged some place. I was actually out of town, so wife dealing with this situation. Date was August 15, 2018. 1st guy came out, looked good, but next day same situation. A very GOOD tech came out who fixed it, we thought. No issue with them coming back out - which was good. Then on 11/5 had new town water meter installed. After install, need to run water from upstairs tub/shower. After a few minutes while I was down in the cellar, water starts coming through the celling! Run upstairs and sinks on 1st floor were overflowing. Shutoff tub, call Mill Town. So for 3rd time they came right out (again good) - asked for same good tech, got him. He fixed, best he could but (this time) put blame on some drain pipe in cellar being too small? They did not charge extra, but said this was last free time for this issue. For this service original date was 8/15/18 and 8/16/18 and wife was charged $287.50. Not sure fair or bad price. So now we are going to have both gas range and dishwasher replaced. Call Mill Town to assist, and also asked for insinkerator (garbage disposal) install, as we had recently changed from septic to in-town sewer. Date was scheduled for afternoon of Wed 11/14, as that was the window Home Depot stated for delivery. Monday AM find that HD will delivery around 11/noon and Mill Town could not come earlier, so had to reschedule. 11/23 was Mill Town first open date. This time scheduled them for AM. Of course this time HD schedules the appliance delivery for 11-3, which I only find out about the night before. Mill Town arrived on-time around 9, un-hooked old range and dishwasher, added new connector for gas, and then installed 1/2 HP garbage disposal, Badger 5. Finished this around Noon, and we are still waiting for HD delivery with no real good info from them. Tech took lunch, and then had to leave, which I understand. Said they would come back to finish. Paid them $1602.60 for install of Garbage Disposal, with new unit (electric already there) and un-hook dishwasher and range, Here maybe 4 hours, even at $200 for equipment, that is $300+/hr??? HD was delayed with appliances (trunk broke down) and actually did not arrive until 5:30 PM. In 15 minutes appliances in house and old removed. Call Mill Town around 5 PM (Friday night) to say appliances would be delivered in next 30 minutes, for which they said if they came out then would be after hour rate. Told to call them back tomorrow. Called them on Sat AM, they said they would try and would contact me back. Never heard from them. Called them back Sat afternoon, told me to call them back Monday AM. Said I wanted to talk to Service Manager, was told they would tell him to call me. Called again Monday AM, said they would put me on stand-by. Why I was not there already after Friday evening and multiple calls on Sat, who knows?? They would call me if they had any openings. Now this is for job I already [over?] paid for. Also on Sunday evening wife was using sink, and with new garbage disposal install, sink was leaking. Turns out no plug in the hook-up for dishwasher, which was not yet installed! Told them this on Sat, still on standby. During day on Monday called them multiple times, same story on standby. Was told later in afternoon (too late) that they had called me 4 times, had tech available, but since no answer they sent him elsewhere. My iPhone showed no messages or no incoming calls, nor did my home phone which has Verizon Fios call screening and mailbox, which sends me an email for any left messages. Again request call from Service Manager - said he would call me Tuesday AM. Now Tuesday evening and no call from either Mill Town or Service Manager. I have at this point in time contact another plumber to try and get some one out. Hopefully someone from another company will be here on Thursday. By then almost a week with no range, no dishwasher and a leaking sink. I have placed a hold on check payment to Mill Town. This is the only thing that I am 100% sure I will get a call back from them about. DO NOT USE THIS COMPANY!! Follow-on - now Tuesday 11/28. I got a friend to help me get a plumber today - Powderly from Billerica (978-663-0164). They came out this AM and finished all to PERFECTION. At least now I have a plumber to call and trust. Cost to me was $275. They said for what I had previously done, probably no more than $200. So total should have been no higher than $600 (on high side), not $1602.60!!! Then perfect timing. No more than 15 minutes after Powderly finishes and leaves, guess who calls? Yes Mill Town, and they think Service Manager had already called and spoken to me, which of course never happened. I am sure the only call I'll receive from Mill Town will be about payment, and maybe this review!"

"Good communication to let me know when the technician was expected to arrive. Technician was knowledgeable and took the time to answer questions. Overall, happy with the experience."

"Seamless. From the moment of making the appointment with the sales rep to come out to the follow-up phone call, I could not have asked for this installation to go better at a difficult time. They listened to my concerns regarding the look on the outside of the house and the location of units inside. They assisted with all aspects of the Mass Save program making the application process easy. They took care of actual submission of the paperwork where most companies wanted to provide the info to me to then submit."

"I would not hire these guys again"
