A panel upgrade in Pasadena is one of those things most homeowners put off until something forces their hand — a breaker that keeps tripping, a letter from their insurance company, or an electrician pointing at a 1970s panel in the garage saying it needs to go. Summer is exactly when that moment arrives. Nothing pushes an old electrical panel harder than an air conditioner running all day in California heat. If you have been thinking about a panel upgrade or wondering if your home can handle everything you are plugging in, this guide will help you understand what is going on, what it costs, and how to get it done without paying full price.
Why Summer Is Hard on Old Panels
Most older homes in Pasadena were built with 100-amp service panels. Back in the 1960s and 1970s, that was plenty. A home back then had a few lights, a refrigerator, and maybe a TV. That is a very different world from today.
Now think about what a modern home in Pasadena runs at the same time: central air conditioning, a refrigerator, a dishwasher, a washer and dryer, several TVs, computers, phone chargers, and maybe an EV charger in the garage. All of that together can push a 100-amp panel to its breaking point before dinnertime.
When summer comes and the AC kicks on all day, the stress goes up even more. Breakers start tripping more often. Some that were barely holding on finally give out. Panels that have been getting by for years show their age when the heat is on. At best, you get annoying outages. At worst, you get a fire risk — because an old panel that cannot trip under overload sends that extra power into the walls instead of shutting the circuit off.
The U.S. Consumer Product Safety Commission says electrical panel failures are one of the leading causes of house fires in older homes. In Pasadena, where a lot of the housing stock was built before 1985, this is not a small risk. It is a real one.
The Signs Your Panel Is Struggling
Your panel will usually give you warning signs before something serious happens. Here is what to look for:
- Breakers that trip when you run two appliances at once — If your kitchen breaker trips every time the microwave and toaster are both on, the circuit is being overloaded. If the breaker trips even with light loads, the breaker itself may be worn out.
- A breaker that keeps tripping and cannot be reset — When a breaker trips and immediately trips again after you reset it, there is a fault on that circuit. Stop resetting it and call a licensed electrician.
- A panel door that feels warm — The outside of your panel should feel close to room temperature. If it is warm or hot, something inside is getting too hot. That is a warning sign.
- A burning smell near the panel — If you can smell something burning near your electrical panel, treat it as an emergency. Something is overheating right now. Do not wait.
- Lights flickering all over the house — When lights flicker on multiple circuits at the same time, it usually means a problem at the main service level, not just one circuit.
- A Federal Pacific or Zinsco panel — These two panel brands have well-documented problems with breakers that fail to trip when they should. Insurance companies flag them. Home inspectors flag them. If you have one, get it evaluated now, even if it is not showing symptoms yet.
How Insurance Companies Are Pushing This Issue in Pasadena
A lot of Pasadena homeowners are getting letters from their insurance company right now. The message is clear: upgrade your electrical panel or we are canceling your policy. This is happening most often with Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco panels, which insurers say carry a higher fire risk.
From our panel upgrade work across Pasadena and Los Angeles County, roughly 4 in 10 jobs we do on older homes are partly driven by an insurance requirement. In most of those cases, the homeowner thought the cost would be huge. Then they found out about the rebates, and the number became a lot more manageable. A panel upgrade that costs $3,500 before rebates can cost under $2,000 after the federal IRA rebate and SCE programs are applied.
The other thing we hear a lot: people waited for the insurance deadline to get close before calling. That is almost always a mistake. Scheduling gets tight as the deadline approaches, and rushed jobs cost more. If you have an insurance letter sitting on your counter, call now while there is still time to do it right.
“Every panel upgrade I do in Pasadena, I open the old box and see the same thing — breakers that have been reset so many times the mechanism is worn out. The breaker still looks fine from the outside, but it will not trip when it needs to. That is the part that scares me most.”

What the Panel Upgrade Process Actually Looks Like
A panel upgrade means taking out your old electrical panel and putting in a new one. For most Pasadena homes, that means going from a 100-amp panel to a 200-amp panel. A 200-amp panel gives you twice the electrical capacity — more than enough for air conditioning, EV charging, and everything else a modern home runs.
Here is how the process works, step by step:
- Assessment visit: A licensed electrician looks at your current panel, checks the service entrance (the wires coming in from the street), and does a load calculation to confirm what size panel you need.
- Permit application: The contractor files a permit with City of Pasadena Building Department. For most Pasadena homes, panel upgrade permits are approved within a few business days.
- Installation day: Power is shut off for a few hours. The old panel comes out, the new one goes in, and all your circuits are reconnected. Power comes back on the same day in almost every case.
- Inspection: A city inspector comes out to check the work and make sure it meets code. A good electrician’s work passes the first time.
- Utility coordination: If the service entrance also needed to be upgraded, SCE comes out to inspect and reconnect on their end.
From the first phone call to a completed inspection, most Pasadena panel upgrades take one to two weeks. The actual installation day is typically four to eight hours of work, during which the power is off. Most families plan around it and stay home for that day.
Panel Upgrade Cost in Pasadena — Before and After Rebates
This is the part most people want to know. Here are realistic numbers for Pasadena projects based on what we actually see:
- 100-amp to 200-amp replacement (no service entrance change needed): $2,200 to $3,800
- 100-amp to 200-amp with service entrance upgrade: $3,200 to $5,500
- 200-amp panel swap (same service size, just replacing the panel): $1,800 to $3,200
- Panel upgrade combined with EV charger installation: $3,000 to $6,000 total — doing both at once saves $500 to $900 compared to two separate jobs
These ranges include the permit fee from City of Pasadena Building Department (usually $150 to $400), all labor, and all materials. They do not include drywall repair if the service entrance work requires opening a wall.
How the Rebates Work
The federal government created the Inflation Reduction Act rebate program, which gives qualifying homeowners up to $4,000 toward a panel upgrade. This is not a tax deduction — it is a direct rebate on the cost of the project. Income limits apply, and the rebate is higher for lower-income households.
On top of the federal program, SCE rebate programs have their own incentive programs for panel upgrades connected to home electrification — things like adding an EV charger or switching from gas appliances to electric ones. These utility programs are separate from the federal rebate and can be stacked with it.
Red Electricians has a dedicated person on our team who handles rebate paperwork for every qualifying project. You do not have to figure out the forms yourself. We take care of it, and the savings come off your final invoice or arrive as a refund, depending on which program applies to your situation.
These programs have funding caps. When the money is gone, it is gone. Homeowners who schedule their panel upgrades while the programs are funded get significant savings. Those who wait may find the programs have changed or closed. According to the U.S. Department of Energy, the IRA programs are among the largest home energy incentive programs in U.S. history — but they are not guaranteed to last forever.
Combining Your Panel Upgrade with EV Charging
If you drive or plan to drive an electric vehicle, your panel upgrade and EV charger installation work perfectly together as one project. A 200-amp panel has room for a 40-amp Level 2 EV charging circuit alongside everything else your home runs — something a 100-amp panel usually cannot do safely.
When you combine both jobs in one visit, the electrician runs the EV charger circuit while the panel is already open. The permit covers both. The city inspection covers both in one visit. Doing it this way saves you money on labor and makes the whole process simpler.
According to the International Energy Agency, EV ownership is growing fast across California. In Los Angeles County, we are seeing this in our scheduling — requests for combined panel upgrade and EV charger jobs have doubled in the past two years.
Planning for Solar and ADUs
If you are thinking about adding solar panels to your home in the next few years, now is the right time to plan for it. Solar systems connect to your main panel, and battery storage systems like the Tesla Powerwall need extra space and specific wiring. An electrician who knows solar can set your new panel up so it is ready for solar when you want it — saving you the cost of modifying the panel a second time later.
California’s ADU (accessory dwelling unit) boom is also driving a lot of panel upgrades in Pasadena. When you pull a permit to build a garage conversion or backyard cottage, the city requires that your main electrical panel can handle the added load. If it cannot — and with a 100-amp panel, it usually cannot — the panel upgrade has to happen before the ADU permit is approved. Plan for this early.
For a full panel installation assessment in Pasadena, contact Red Electricians. We cover all of Pasadena and Los Angeles County with licensed, permitted, and inspected work. If your project also includes plumbing — common during ADU construction — our partner network includes a Irvine plumber for customers who need both trades coordinated.
How to Get a Good Quote
When you call for a panel upgrade quote in Pasadena, having this information ready helps the electrician give you an accurate number without a lot of back-and-forth:
- The brand and amp rating of your current panel (on the door or a label inside)
- Approximate age of your home
- Whether you have or plan to add an EV charger or solar system
- Whether your property has a detached garage, pool equipment, or workshop with its own subpanel
- The name of your insurance company if they sent you a notice about the panel
Always ask for the quote in writing. Make sure the permit fee is included. Ask whether the company handles rebate paperwork as part of the job. And ask what panel brand will be installed — Square D, Eaton, and Siemens are the ones with the best track records and the widest parts availability in Los Angeles County.
Panel repair is sometimes the right answer for a specific problem, but a full replacement is almost always the better long-term investment when the panel is old or flagged. Your electrician will tell you which makes sense after looking at your specific situation.

Frequently Asked Questions About Electrical Work in Pasadena
Before scheduling any electrical project, homeowners in Pasadena typically have a few common questions. Here are direct answers to the ones we hear most often:
How long does the average panel upgrade take in Pasadena? A standard 100-amp to 200-amp panel upgrade takes one installation day — typically four to eight hours for the electrical work — plus the time for the permit approval and the post-installation inspection. From first call to completed inspection, most projects take one to two weeks total.
Will my insurance go down after a panel upgrade? Some insurance carriers offer lower premiums for homes with updated electrical systems. More commonly, the benefit is the elimination of a surcharge or the restoration of coverage that was being canceled or non-renewed because of the old panel. Contact your carrier directly after your upgrade is complete and the inspection is signed off to ask about any premium adjustment.
Can I stay in my home during the work? Yes, for panel upgrades and most electrical projects. There will be a period during installation day — typically four to eight hours — when the power is off to the whole house. For rewiring projects, power is off in the areas being worked on but usually maintained in other areas. The electrician coordinates with you on the schedule to minimize disruption to your daily routine.
What is the difference between a panel upgrade and a service upgrade? A panel upgrade replaces the main panel box and the breakers inside it. A service upgrade also replaces the service entrance — the wiring from the utility meter to the panel. Some properties need both; others only need the panel. The assessment visit determines which scope your property needs.
