Residential Electrical Services in Merrimack

Commonly asked questions by Merrimack residents

  • How do I know if my Merrimack home needs a panel upgrade?

    The most common signs are frequently tripped breakers, a panel that feels warm to the touch, flickering lights when appliances kick on, or a panel that's simply decades old. If your home was built before 1990 and has never had the panel replaced, it's worth having an electrician take a look.

  • Do you pull permits for residential work in Merrimack?

    Yes. Any work that requires a permit under New Hampshire electrical code gets one. We don't skip that step to save time, and we'd encourage you to be skeptical of any contractor who suggests otherwise.

  • How long does a typical residential electrical job take?

    It depends on the scope. A straightforward outlet installation or fixture swap might take an hour. A full panel replacement is typically a half to full day. An EV charger can be installed in a days work. We give you a realistic time estimate before we start so you can plan around it.

  • Can you work around my schedule?

    We do our best to accommodate homeowners who work during the day. When you call Gagnon's Electrical Services, we'll find a time that works for both of us.
