“Highly Recommend — Honest, Professional, and Great Value. Zero Homes recently replaced my old furnace and AC with a heat pump and high-efficiency gas furnace. I worked with Conner on the initial quote — he was incredibly honest, transparent, and took the time to walk me through multiple options, helping me understand the pros and cons of each. Their pricing was very competitive compared to other vendors.”
Electrical Panel Upgrades
Electrical Panel Upgrades
Your electrical panel is the hub that powers every circuit in your home. An upgrade replaces an older or undersized panel with a modern, higher-capacity one, so it can safely run today's electric equipment, a heat pump, a heat pump water heater, an EV charger, or an induction range. Many older homes top out at 100 amps or an aging fuse box, and electrification usually needs more room than that. We size it right, pull the permits, and coordinate the utility, so your panel is ready before the new equipment arrives.

The Basics
What Is an Electrical Panel Upgrade?
Your electrical panel, sometimes called the breaker box or service panel, takes the power coming into your home and splits it across the circuits that run your lights, outlets, and appliances. Every panel has a capacity, measured in amps, and a fixed number of breaker slots.
An upgrade means swapping an older or maxed-out panel for a larger, modern one, most often a 200-amp panel with open slots for new circuits. Depending on your home, that can be a straight panel swap, a full service upgrade that involves the utility and your meter, or, in some cases, a smart panel or subpanel that adds capacity without a full replacement.
You don't always need one. But when you're adding several large electric loads at once, an upgrade is what makes the rest of your electrification possible, and safe.
Find Your Fit
Do You Need an Electrical Panel Upgrade?
Not every home does. It comes down to your panel's age, its capacity, and how much you're adding. Here's how it usually breaks down.
Best For
If any of these sound like your home, a panel upgrade is the right path.
- 100-amp service, a fuse box, or anything smaller
- A panel with no open breaker slots left
- Older or recalled panels (Federal Pacific, Zinsco, Challenger) that aren't safe to add to
- Planning several electric upgrades, heat pump, water heater, EV charger, induction range
- Adding a large 240-volt load like an EV charger or a whole-home heat pump
Not the Right Fit
If a full upgrade isn't necessary, your Home Advisor will tell you.
- A modern 200-amp panel with open slots and headroom to spare
- A single small addition that fits inside your existing capacity
- Cases where a smart panel or load-management device can free up room instead of a full replacement
Not sure? Your Home Advisor will tell you straight on the first call, no upsell.
