Merrimack Valley Plumbing, LLC is a locally-owned and operated company committed to providing fast, affordable, and high-quality Plumbing. We offer HVAC repair, installation, and replacement services. We specialize in heating controls and simplifying complicated plumbing and HVAC systems to make them user-friendly. We strive to find solutions that fit everyone’s comfort needs, from construction projects to air conditioner replacement.
"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."

Gas fireplace repair services FAQs
Fixing a gas leak costs about $45 to $150 per hour for a plumber or gas line specialist. The job’s overall cost will vary depending on the location of the leak. A leaky junction or connection behind the stove or dryer will likely cost about $120 to $170. But for a leak that requires a gas fitter or plumber to excavate a pipe in the yard, the cost could rise to $1,500 to $5,000. Keep in mind that gas leaks are very serious issues, so don’t hesitate to contact a plumber or gas line specialist immediately.
The cost to install a fireplace is $2,440 on average. This cost can range from $150 to $8,000 or more, depending on the type of fireplace, the materials used, and the size.
Electric fireplaces cost around $1,000 to install, and mostly only require wiring installation. Installing a wood fireplace from scratch could cost upwards of $10,000, depending on the foundation needed to support the weight of the fireplace. In addition, gas fireplaces can cost between $2,500 and $10,000.
The cost to remodel your fireplace is $1,200 on average. This cost can range from $400 to $2,000, depending on the extent of work needed.
If you add a hearth to your fireplace, you can expect to pay between $3 and $200 per square foot. However, if you're refacing your fireplace, the price tag will depend on your chosen materials. If choosing tile, you can pay between $1 and $50 per square foot, depending on the design. Stone is a more expensive material, averaging between $60 and $70 per square foot.
Yes, it can be worth installing a gas fireplace, depending on your home heating needs. The cost to install a gas fireplace can be much lower than the cost to install a comparable wood-burning fireplace. The convenience of starting a fire with the flip of a switch and turning it off just as quickly makes a gas fireplace a big time saver over starting and maintaining a wood-fueled fire. A gas fireplace also does not require ash cleanup or frequent chimney cleaning to remove creosote and other buildup that can lead to chimney fires. Gas fireplaces burn and heat much more cleanly than wood fireplaces.
A gas fireplace insert costs about $3,600 to install, on average. The cost to install a gas log insert ranges from about $700 to $6,500, depending on the size, type of insert, how it works, and heating needs. Gas fireplaces need electrical and gas lines installed properly, so hiring a pro is recommended rather than trying to DIY installation.
