- JMJennifer Marcolongo3 days ago5.0Gallagher Electric, Inc., are a couple of very responsive, respectful, and responsible electricians! I have been having John and his company service my electrical needs for over 15 years, and they are the only electrician I would trust! I feel they know their work technically, of course, but are also really approachable and respectful of the home, kiddos, pets, the mess...! Truly dependable company, and the alarm system they offer is really the best value around!
- PKPeter KornikJul 2, 20265.0I have been a Merrimack resident for 20 years, and that whole time dealing with an improperly wired garage. The Gallagher Electric team did amazing work in 1/3 the time I was expecting, and at a fair price. For once, everything connected to the electrical box in my garage (inside lights, outlets, attic lights, garage door opener, exterior lights, pool pump) all work and are to the latest safety codes. I couldn’t be happier!
- JVJan White (VegasLady)Jun 12, 20245.0All the staff at Gallagher Electric are friendly and polite. They respond promptly when any issues arise. My new generator install and subsequent routine maintenance were performed as promised. I would highly recommend them for your generator needs.
- SPSteven PiniApr 20, 20235.0Gallagher Electric installed a whole house generator after 3 separate power outages in our neighborhood this winter. They were prompt, reasonably priced, and an authorized Generac dealer which came with a 7 year warranty because of the special Generac was running. The entire electrical install took a day followed by a propane install a couple days later. I would highly recommend John Gallagher and his team! Update in 2024: I had them do another project for me this year (hook up a hot tub) and they again provided exceptional service - helping through the permitting process, showed up when they said they would, and left the job site looking great when they were done.
- JMJoan ManningMay 4, 20225.0I highly recommend Gallagher Electric for any home needs. John installed a full-house generator for me and has done other electrical work in my home. He is responsible, dependable, professional and an overall nice guy. I’m proud to support local, small businesses in NH. Joan Manning
