Safe, code-compliant panel and service upgrades for New Gloucester homes and businesses — from 100-amp to 200-amp service and beyond.
About 68 percent of occupied homes in New Gloucester heat with oil, the highest share in Cumberland County, and that single number drives most panel upgrades here. An oil boiler or furnace draws very little electricity, so many houses were built with a 100-amp service that was fine for decades. Replace that system with cold-climate heat pumps, add a heat pump water heater, and the winter load can outgrow the service quickly. Add an EV charger or an electric range and a load calculation often shows a 200-amp service is needed before the first heat pump is mounted. Doing the upgrade first, rather than squeezing heat pump circuits into a full panel, also avoids the double-tapped breakers and overloaded feeders that turn up when equipment is added piecemeal over several winters.
The age of the house shapes the job. Most New Gloucester homes were built after 1980 and usually have breaker panels that are sound but full, where a subpanel or a service upgrade adds room. The older village homes and farmhouses, about 11 percent of the housing, can still have fuse boxes, 60-amp services or panels from brands such as Federal Pacific and Zinsco that are worth replacing outright. A full upgrade typically includes a new meter socket, service entrance cable, panel and grounding, and Goodnow Electric pulls the New Gloucester electrical permit and coordinates the Central Maine Power disconnect and reconnect.
About one home in five in New Gloucester is in a two- to four-unit building, a higher share than any other town in the county except Portland and Westbrook. In those buildings, each unit usually has its own meter and panel, the meter bank is shared, and upgrading one apartment for heat pumps can raise questions about the whole building's service. Mobile homes, about 8 percent of the housing, often take power from a pedestal or pole that is part of the upgrade. Whole-home surge protection is a sensible addition while the panel is open, and a free written estimate lays out the options first.

“We had a major issue happen near Easter, we called multiple people, this company was right on ball calling us back. He is amazing, instead of making us feel insecure he assured us that we was in right direction, took time out of his own day to answer us after hours and even called back for a follow…”
