Why Plaistow and Haverhill Homeowners Are Upgrading to 200-Amp Service Before Fall

FOR IMMEDIATE RELEASE

PLAISTOW, N.H., July 7, 2026 – Moore Electric is upgrading a steady run of southern New Hampshire and Merrimack Valley homes from 100-amp to 200-amp electrical service this month, as peak-summer air conditioning and heat-pump use pushes older panels past what they were built to handle.

Most of these homes were wired decades ago for a lighter load. Run central air, a heat pump, the fridge, and the dryer at the same time on a hot July afternoon, and a 100-amp panel is carrying more than it was ever meant to. Homeowners who see the strain now are choosing to fix it before fall, instead of waiting for heating season to add even more demand.

What an overloaded panel looks like

A panel usually gives you warning signs before a breaker quits for good. Lights that dim or flicker when the AC or a big appliance kicks on. A breaker that trips again and again during normal use. A panel cover that feels warm to the touch, or a steady buzzing from the breaker box. Any one of those is worth a look. Together, they point to a panel that is running at its limit.

“A lot of homes around here still run on 100-amp service that was fine in its day, but it was never sized for a heat pump and a couple of AC units all pulling at once,” said Brenden Moore, Master Electrician and owner of Moore Electric. “When I open up a panel in July, I can see where it’s been working too hard. Moving up to 200 amps takes that pressure off, and doing it now means it’s handled before the heat turns back on in the fall.”

A 200-amp service gives a home the headroom for the equipment people are actually adding: modern high-efficiency HVAC, an EV charger in the garage, a bigger kitchen. Booking the work in mid-summer also means a calmer schedule. Once cold weather hits and heating systems come back on, panel and service upgrades stack up fast.

Moore Electric handles the full upgrade, from pulling the permit and coordinating with the utility to the final inspection. Brenden Moore is personally on every job, the same way he has run the business for more than 25 years.
