If you’re considering installing a heat pump in your Hillsboro or Beaverton home, congratulations — you’re making a smart investment in efficiency and comfort. But before your contractor breaks ground, there’s a critical conversation to have: your electrical panel. Many homeowners in the Portland Metro area are surprised to learn that their existing electrical service can’t support a modern heat pump. Here’s what you need to know.

The Demand: Why Heat Pumps Need More Power

A heat pump is fundamentally different from the forced-air furnaces and window AC units that many Oregon homes still rely on. Instead of burning fuel or running a traditional compressor intermittently, a heat pump uses electricity to move heat in and out of your home year-round. In winter, it heats your house by extracting warmth from outside air and pumping it in. In summer, it reverses the cycle.

This constant, efficient operation requires more electrical capacity than most older panels can provide. Most homes in Hillsboro, Beaverton, Forest Grove, and Cornelius built before 2000 have 100-amp electrical service. Many have only 60 amps. A typical heat pump installation requires 200-amp service — sometimes even more if you’re also planning EV charging, a backup generator, or a hot tub.

What Does a Panel Upgrade Involve?

An electrical panel upgrade replaces your existing service panel with a modern one that can handle higher loads. The process typically includes a site assessment where an electrician evaluates your current service, load requirements, and the distance from the utility meter to your panel. Then comes permitting — local building departments in Hillsboro, Beaverton, and other Portland Metro cities require permits for panel work to ensure safety. Your electric utility may need to upgrade the lines serving your home, and then a licensed electrician removes the old panel and installs the new one, rewiring circuits as needed. Finally, a building inspector signs off before the system is energized. The entire process typically takes 3–7 days.

The Financial Picture

An electrical panel upgrade in Oregon typically costs $3,000–$6,000, depending on your home’s current setup and local labor rates. This might seem expensive — and it is a real investment — but consider the long-term benefits: heat pumps are 2–4 times more efficient than traditional furnaces and AC units, meaning lower heating and cooling bills every month. Oregon’s cool climate is ideal for heat pumps, allowing them to operate efficiently even in winter. An upgraded panel future-proofs your home for EV charging, backup generators, and other electrical upgrades. And you’ll see increased home value — buyers appreciate modern electrical systems and efficient HVAC.
