"Duct Kings was fantastic! Jeremiah was very helpful on the phone, answering all of my questions and scheduling my appointment. Daylis did an amazing job cleaning my a/c and dryer ducts and vents. She was professional, courteous, knowledgeable, and thorough. I highly recommend Duct Kings!"

"The technicians came on time, found the issue and presented an estimate SO QUICKLY, and the follow up visit is already scheduled! So impressed with their turnaround time, professionalism, and friendliness. 5+++"

"It went very well. The men were very thorough in their work. They were very friendly. They were on time. One of them cleaned our ceiling fans even though that was not required to be done. It was very thoughtful of him (I think it was John)."

"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."

"Good. No complaint"

"It's the worst air duct cleaning company. Last week, they came and performed air duct and dryer vents, unfortunately, lot of dust still coming through the system. When j went and checked filter lot of dust piled up on the filter. The person who came up for air duct cleaning told me while leaving, he had cleaned filter, need not replace it for another 2months, but the very next day itself when I went checked lot of dust piled up onto filter."

"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 booked a service and was given a 4 hour window. The technician apparently arrived about 1 hour before the window, claimed to have called me but left no message and simply left with no availability during the actual 4 hour window that was promised. This is poor service and I have no heat. Unbelievable and unprofessional."

"Starting the project this week but I wanted to cancel the job so the other five know."

"Rob had recently replaced my kitchen and bathroom faucets and I called him to see if he could now replace my gas water heater. I was happily surprised when he said he’d be out within a couple of days and I was REALLY pleased with his estimate. For both jobs, Rob showed up when he said would and was both fast and efficient. He’s a great guy - dependable, reasonable, professional and focused on providing good service to his customers. Rob is my “go to” plumber from now on!"
