Electrical Panel Upgrades
in Southern NH
100A to 200A service upgrades, full panel replacements, sub-panels, and dedicated circuits by licensed NH electricians. Built to support EV chargers, heat pumps, additions, and modern electrical loads.
When Does a Panel Need an Upgrade?
Many Southern NH homes have 100-amp service or older panels, but age or service size alone does not determine whether an upgrade is needed. Before adding an EV charger, heat pump, hot tub, or major addition, our electrician completes the required load calculation and inspects the equipment. If the service needs more capacity or the panel condition calls for replacement, we coordinate the permit, utility work, meter equipment when required, panel replacement, and final inspection.

Frequently Asked Questions
How do I know if I need a panel upgrade?
Frequent breaker trips, damaged or overheated components, no room for required circuits, and panels with known safety concerns such as older Zinsco or Federal Pacific equipment are reasons for an electrician to evaluate the service. Planning an EV charger, heat pump, hot tub, or addition is another good time to review capacity, but a 100-amp service does not automatically need replacement. We inspect the panel and complete the required load calculation before recommending an upgrade.
How much does a panel upgrade cost in Southern NH?
A 200A panel upgrade in Southern NH typically runs $3,500 to $6,000 depending on whether a new meter base is required, the complexity of the existing wiring, and utility coordination needs. We provide free written estimates.
How long does a panel upgrade take?
Most panel upgrades are completed in one day. We coordinate with the utility for any required power shutoffs and schedule the inspection. Power is restored the same day in most cases.
Do I need to coordinate with Eversource myself?
No. A.J. LeBlanc Heating handles all utility coordination with Eversource, Unitil, or Liberty on your behalf, including the disconnect, reconnect, and any required permits.
Do you replace Federal Pacific and Zinsco panels?
Yes. Federal Pacific Stab-Lok and Zinsco panels are widely recognized as a safety concern, and we recommend a licensed evaluation to determine whether replacement is needed. We replace these panels with modern 200A service throughout Southern NH.
