Electrical Panel Upgrades for Heat Pumps: When Might You Need One?

A heat pump needs its own 240-volt circuit, and electric backup heat can add a large load. Whether your panel can handle it depends on its size, your other appliances and a load calculation by a licensed electrician.

When an upgrade is more likely

  • The home has a 100-amp (or smaller) service.
  • The panel has no space for a new double-pole breaker.
  • You are adding other large electric loads at the same time, such as an EV charger, electric range or electric water heater.
  • The heat pump uses large electric backup heat strips.
  • The panel is old, damaged or a type electricians recommend replacing.

How an electrician decides

A licensed electrician performs a load calculation based on the electrical code: the square footage of the home plus its major appliances. If the calculated load exceeds the service, options include:

  • Upgrading the panel and service (for example, 100A to 200A).
  • Adding a load management device or smart panel that limits large loads from running at the same time.
  • Choosing a variable-speed heat pump with smaller backup heat.

Typical costs

ItemTypical cost
Panel upgrade or replacement$521–$2,103 (about $1,286 average)
200A panel installed$750–$2,000
100A to 200A service upgrade$750–$2,000
Meter box install or replace$200–$800

Most panel and service upgrades require a permit, and your utility may need to disconnect and reconnect power.

Ask HVAC contractors whether their quote includes the electrical work, or whether you need a separate electrician. See heat pump vs. AC and furnace and electrical panel replacement cost.
