New Hampshire is in Climate Zone 6 - Cold (heavy heating, light cooling). Homes here typically have higher heating demands than cooling.
EV charging calculations consider your driving and electrical situation:
EV charger installation should be done by a licensed electrician because:
For plug-in hybrids or low-mileage drivers (under 30 miles/day), yes. For full EVs with typical driving (40+ miles/day), Level 1 is usually too slow to fully replenish overnight.
Expect $500-2,000+ for installation depending on complexity. If your panel is full or undersized, add $1,500-3,000 for panel work. The charger unit itself runs $300-700 for most Level 2 options.
If you're running a 240V circuit, you need an electrician in most jurisdictions. The electrical work requires permits. Some portable chargers that use existing 240V outlets (like dryer outlets) don't require new wiring.
32A is most common and handles most EVs' maximum charge rate. 48A is better for future-proofing or high-capacity EVs. Match the charger to your car's maximum charge rate and your available electrical capacity.
