Learn moreElectrical & Generator FAQ
What size generator do I need for my home?
Generator size depends on the circuits and equipment you want available, their running and starting loads, the fuel supply, and any load-management plan. Our electrician and fuel gas fitter review those conditions before recommending equipment.
How much does home EV charger installation cost?
A Level 2 home EV charger installation (240V, 40-50 amps) typically runs $1,000 to $2,500 in Southern NH, depending on the distance from your panel and whether a panel upgrade is needed. Our quote identifies the electrical work, permit, and inspection scope. We provide free estimates and coordinate required permits and inspections.
What is a whole-home standby generator?
A standby generator automatically turns on within seconds of a power outage, with no action required. It's permanently installed outside your home and connects to your natural gas or LP line, for hands-off backup without gasoline refueling. Unlike portable generators, standby units run automatically whether you're home or away, and can power your entire home or just essential circuits.
Do I need a panel upgrade for an EV charger or heat pump?
Possibly. An EV charger or heat pump adds electrical load, but a 100-amp service does not automatically require replacement. Our electrician reviews the panel, existing loads, equipment requirements, and available load-management options before recommending an upgrade. If the existing service cannot safely support the project, we explain why and include a clear quote.
Are your electricians licensed in New Hampshire?
Yes. Our electrical work is performed by New Hampshire-licensed master and journeyman electricians, and A.J. LeBlanc Heating is fully insured. Our electricians are background-checked employees. We obtain permits and coordinate inspections when the work requires them.
