Electrical Panel Upgrade in Glendale, Peoria and Sun City
Your electrical panel is the center of the house. Every circuit starts there, and when it is old, undersized or damaged, the rest of the system pays for it. A panel upgrade replaces the main breaker panel with one built for how you use power now, with room for the circuits you need and breakers that actually protect the wiring behind them. It is one of the most useful electrical projects an older home can have.
Vortech handles panel upgrades from start to finish: sizing the new service, pulling the permit, coordinating the power shut off with the utility, installing and labeling the panel, and meeting the inspector. Panel work is done under ROC 341933 (CR-11 Electrical). We do not do this as a rushed swap. Panels deserve careful work because everything in your home depends on them. Expect clear answers and no surprises about the process.

How the Job Goes
- Evaluate the panel and loadWe look at the existing panel, service size and condition, and add up your real and planned loads, such as AC, EV charging and appliances, to recommend the right size.
- Permit and utility coordinationWe submit the permit and coordinate with the utility so the power can be disconnected and reconnected safely and on schedule. We keep you informed about the schedule at every stage so you can plan around the outage.
- Replace the panelPower is shut off, the old panel is removed, and the new panel and breakers are installed, with circuits reconnected, labeled and grounded to code.
- Inspect and restore powerThe inspector reviews the work, the utility restores service, and we test every circuit and walk you through the new panel. You get a clearly labeled panel and the confidence that it passed review.
Why This Matters in Arizona
Arizona homes lean on electricity more than most. Air conditioning is the biggest load and runs for much of the year, so panels in the West Valley spend long summer afternoons at heavy draw, which wears breakers and connections. Many homes in Sun City, Sun City West and older parts of Glendale were built decades ago with 100 amp or smaller service and few circuits, and they now need to carry replacement AC units, mini splits, and increasingly EV chargers. Monsoon surges add stress on top of that. Upgrading the panel is often the step that makes all of those additions safe, and it prepares the house for whatever you plan next.
How Much Capacity Does Your Home Need
Service size is measured in amps. Many older homes have 100 amp service, which can be enough for a modest house with gas appliances, but it gets tight fast once you add central AC, an electric range, a pool pump and an EV charger. A 200 amp service is the common choice for most modern homes because it leaves headroom for those loads and for future additions. Capacity is about the whole house, not one appliance, so the calculation looks at everything running together on a hot day.
The right size is not a guess. We total up the connected load and what you plan to add, then check whether the service entrance and meter base can support it. Sometimes the answer is a larger panel with the same service, sometimes it is a full service upgrade. Cost depends on which one applies, the location of the panel, and the condition of the existing equipment. Either way, you get a recommendation with the reasoning behind it.
Permits, Inspection and the Utility
Panel replacement requires a permit in Arizona, and the work is inspected before power is restored for normal use. In cities like Glendale, Peoria and Surprise the permit goes through the city. In unincorporated areas like Sun City and Sun City West, permits generally go through Maricopa County. We handle the paperwork and the inspection appointment so you do not have to. Permits also mean a second set of eyes confirming the work is safe, which matters for insurance and for resale.
Because the main service is involved, the utility is part of the job. Power must be disconnected before work and reconnected after approval, and that scheduling affects how long you are without power. Timelines vary with permit processing, inspector availability and utility scheduling, which is why we explain the sequence at the start rather than promising a day. We keep you updated at each stage so you can plan around the outage and the inspection.
Most Asked Questions About Electrical Panel Upgrade
What homeowners search for most, answered.
Do I need 200 amp service?
You may need 200 amp service if your home draws more than your current service can supply. Many newer homes are built with 200 amp service, and older ones often have 100 or 150. Large central air conditioners, electric ranges, pool equipment, EV chargers, electric water heaters and added square footage all push demand up.
How do you remove a circuit breaker from a panel box?
Removing a circuit breaker from a panel box is work for a licensed electrician. Even with a breaker switched off, the main lugs and bus bars inside the panel stay live unless the main service is shut off at the meter, and a slip can cause serious shock or an arc flash.
How many sub panels can you have on a 200 amp service?
There is no simple fixed number of sub panels on a 200 amp service, because what limits you is the total load, not the count. A sub panel is fed by a breaker in the main panel, and the combined demand of everything must stay within what the service can supply.
How do you upgrade an electrical panel in a home?
A panel upgrade is performed by a licensed electrician with a permit. The process generally includes a load calculation, coordination with the utility to disconnect and reconnect power, replacing the panel and meter base if needed, new breakers and grounding, labeling and an inspection by the city or county.
Frequently Asked Questions
How do I know if my panel is outdated?
An outdated panel often shows rust, scorching, frequent tripping, no spare slots, or fuses instead of breakers. Age matters too, because panels from several decades ago were not designed for modern loads. An electrician can inspect the panel and tell you whether it is safe to keep or should be replaced.
Should I choose 100 amp or 200 amp service?
Most homes with central AC, electric appliances or an EV charger benefit from 200 amp service. A 100 amp panel can work for a small home with modest loads, but it leaves little room to grow. We calculate your actual load before recommending a size.
How long will I be without power during a panel upgrade?
The power is off for part of the day while the old panel is swapped for the new one, with additional time depending on inspection and utility reconnection. We plan the sequence with you ahead of time so you know what to expect and can prepare.
Does a panel upgrade require a permit?
Yes. Panel replacements in Arizona require a permit and an inspection, whether through the city or Maricopa County. The permit protects you by confirming the work meets code, and it is part of what we handle for each upgrade. We also schedule the inspection and meet the inspector on site when needed.
Can a new panel handle an EV charger and a mini split?
Usually yes, if the panel and service have enough capacity. Both EV chargers and mini splits need dedicated circuits, and a load calculation shows whether your current panel can support them or whether an upgrade is needed first. If it cannot, we explain the options and what each involves before you decide.
Will a panel upgrade lower my electric bill?
No, a new panel does not reduce the energy you use. What it does is make your electrical system safer, more reliable and able to handle new equipment. The savings, if any, come from the efficient equipment you can now install, not the panel.
