How Can We Help? Let Us Reach Out To You.
Merrimac is one of the smaller towns in the Merrimack Valley, tucked along the river just south of the New Hampshire line, with a rural character that has changed less than many of its neighbors. 128 Plumbing, Heating, Cooling, & Electric has served Massachusetts and New Hampshire homeowners since 1992, and we know Merrimac’s mix of older riverside homes and newer rural construction well. Instead of juggling separate contractors for each system in your home, our team handles it all, from a leaking pipe to a failing heat pump to an outdated electrical panel, with upfront pricing and licensed, insured technicians on every job.
