What size generator do I need for my home?
Generator sizing depends on which circuits and appliances you want powered during an outage. A 10-14kW standby unit can power most essential loads in a typical NH home. A 20-22kW unit covers larger homes or those with electric heating or heat pumps. We do a free load assessment to recommend the right size for your specific home, not just the most expensive option.
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 quotes include all electrical work, permits, and inspection. We provide free estimates and handle all permitting and inspection.
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, so it never runs out of fuel. 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. Many older NH homes have 100-amp panels that are already near capacity. Adding a 40-50 amp EV charger circuit or a heat pump often requires upgrading to a 200-amp panel. We assess your current panel during the estimate. If an upgrade is needed, we'll tell you upfront with a clear quote.
