Your house was wired for a stove and a furnace. A permitted 200-amp service means the EV, the heat pump, and the air conditioning stop fighting each other.
Most sites make you book a visit to hear a price. Here is the honest range for a 100-amp to 200-amp service upgrade in Orange County, and the things that move it up or down. Your fixed quote comes after a free 45-minute assessment — no allowances, no day-of surprises.
Ranges reflect typical Orange County pricing for a full 200-amp service upgrade. Your quote is fixed in writing after the assessment and does not change unless you change the scope.
Open any panel door and you'll find a hand-written index of what each breaker feeds. This is ours — the work we take on, and the work we'll quote you separately for.
Send a photo of your panel door and your zip code. We'll read the label, tell you what service you have now, and say plainly whether you need an upgrade — before anyone visits.

We read your panel, count the circuits, and calculate what your household actually draws against what the service can carry.

“Our insurer sent a non-renewal letter over the old Zinsco panel. They pulled the permit, dealt with the city and the utility, and had it swapped in a day. We sent the sign-off to the insurer and the policy went through.”Homeowner, Anaheim1953 build · 100A to 200A upgrade Placeholder testimonial — replace before launch
If yours isn't here, ask it on the form and we'll answer before we ever talk about scheduling.
In Orange County, a 100-amp to 200-amp service upgrade typically runs $2,500 to $6,500, including the city electrical permit. A straightforward swap in the same location sits at the low end. A new service mast, a panel relocation, or a utility-required meter-main combination moves it toward the top. You get a fixed written number after a free 45-minute assessment.
Four to eight hours on install day, and you get power back the same afternoon. The whole project runs two to three weeks from your first call to final inspection sign-off — the permit is the slow part, not the work.
If you are not adding load and nothing is tripping, 100 amps may be fine. You likely need the upgrade if you are adding a Level 2 EV charger, a heat pump, or central air; if your panel is full and has no room for another breaker; or if your insurer has flagged the panel. The free assessment includes a load calculation, and if the honest answer is that you don't need an upgrade, we will tell you that.
These panels are known to fail to trip under fault conditions, which is why many insurers will not renew a policy while one is installed. Replacement is the accepted fix — swapping individual breakers does not solve it. If you have one, treat it as the reason to move now rather than later.
Yes. We file the electrical permit with your city, schedule the utility to pull and reset the meter, and meet the inspector on site. You do not call city hall, and the permit fee is inside your quoted price rather than added afterwards.
No. The number in your written quote is fixed and covers the panel, labour, permit, and utility coordination. The only way it moves is if you change the scope — for example, adding an EV charger circuit while we are already there. Anything we find during the assessment, such as a corroded mast, is priced before you sign, not after.
Mostly not, as of 2026. SGIP closed its ratepayer-funded budgets at the end of 2025 and TECH Clean California closed single-family reservations in November 2025. SCE's Charge Ready Home program is still open for panel upgrades but is income-qualified, so most Orange County homeowners will not qualify. We will not quote you a rebate we have not confirmed is live that week.
A person reads it, usually within the hour during business hours. If you sent a photo of your panel door we will tell you what service you have now and whether you need an upgrade at all — by text or email, whichever you chose. Only then do we talk about booking the free assessment. There is no obligation and no deposit at any point before you sign a written agreement.
Three short steps. Nothing on the first two identifies you, and we only ask for contact details once you have told us what you need.
