Question 1

Do I need to upgrade my electrical panel for a heat pump?

Accepted Answer

Most heat pump systems require a 240V, 30–60 amp circuit. If your home already has electric HVAC (central A/C), the existing panel is likely adequate. If you're replacing a gas-only system in an older home with a 100-amp panel that's already near capacity, a panel upgrade to 200 amps may be needed. An electrician can perform a load calculation to determine if your current panel has enough headroom.

Question 2

How much does an electrical panel upgrade cost?

Accepted Answer

An electrical panel upgrade from 100 to 200 amps costs $1,500–$4,000 on average, including labor and permits. Costs vary by region and whether the utility needs to upgrade the service entrance. Some utilities offer rebates for panel upgrades associated with electrification. The federal home improvement tax credit provides 30% back on panel upgrades required for heat pump or EV charger installation (up to $600 per year).

Question 3

What size electrical panel do I need for a heat pump and EV charger?

Accepted Answer

A 200-amp service panel is sufficient for most homes with a heat pump, heat pump water heater, Level 2 EV charger, and standard appliances. For homes adding multiple high-load appliances simultaneously, a load calculation is essential. Smart panels (Span, Leviton) allow load management that can often defer or eliminate a panel upgrade by intelligently prioritizing circuits.
