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."

"With the latest job John and his team completed for us, I am now able to say that for the better part of two decades, the electrical work needs of four generations of my family have been completed by 4th Generation Electric. As John and I were catching up before the install of our transfer switch and generator hook up, he recalled when we first met almost 20 years ago. From that time forward, he and his teams have completed work for my family that spanned from outlet installation and replacement, wiring our full new build construction home, inclusive of aiding with the installation of the power line from the street (which was 700 feet away from the house), outside patio electrical work for an elaborate tiered landscape, generator hook up requirements, among other things. Just as our electrical needs grew over time, and John and 4th Generation Electric have as well, the same level of attention to detail, focus on customer satisfaction, and not only the desire to strive for perfection but the expectation to do so, has been the standard that he knows not only his customers expect but that he expects for himself and his teams. It’s easy to write a review like this when it writes itself. If you have any sort of electrical work needs, big or small, you’d be doing yourself a disservice not asking John for a quote."

"Joe O'Connell did extensive rewiring to replace knob/tube wiring in our 150 year old house. The project involved running new wires through walls and ceilings into over six rooms, along with upgrades to electrical panels. Joe and his assistant were very courteous and respectful - they were careful to cover the hardwood floors and use drop cloths to control the dust, and vacuumed up at the end of each day. Joe did great work, everything to code, no cut corners, and brought to my attention some concerns outside the scope of the project that we also had him address. He is a good communicator and returns phone calls promptly. I completely trust him and the work he does, and recommend him highly."

It’s important to ask an electrician a few questions before you commit to hiring them so you can make an informed decision as a consumer. If you’re getting estimates or considering hiring an electrician, ask them these questions:
Are you a full-time electrician?
Are you bonded, licensed, and insured?
What level of experience do you have as an electrician?
Can you please share three references?
Do you do residential or commercial electrical work?
What kinds of electrical work are you most familiar with?
Will any subcontractors be performing the work?
Are permits and inspections required?
Who is responsible for obtaining permits and inspections?
What is your schedule?
Do you offer a guarantee or warranty on your work?
Will you sign a do-not-exceed clause to keep the job within the budget?
Yes, you should get a quote or an estimate from an electrician. Most electricians offer free estimates or quotes. When getting quotes, do your research and verify each electrician’s license. Get quotes from three different electricians to compare. If the prices or items listed appear different on the quotes, ask the electrician to clarify. Learning as much as you can about the electrical work you want done will help you get the most accurate estimate.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
