Your home may need a panel upgrade if breakers trip often, lights dim when big appliances turn on, the panel feels warm or buzzes, or you’re adding an EV charger, a pool, or a remodel. A licensed electrician can check your panel’s capacity and tell you whether an upgrade or a simpler fix makes sense.
If you live in Queen Creek, San Tan Valley, Gilbert, Mesa, or elsewhere in the East Valley, here’s what those warning signs mean, what we check on site, and how Henderson’s Electric Solutions handles the permit and utility shutoff when an upgrade is the right call.
What are the warning signs of an overloaded or aging panel?
These are the signs homeowners and inspectors most often notice before a panel or service upgrade:
- Breakers that trip often, especially when the AC, oven, dryer, or other big loads start at the same time
- Lights that dim or flicker when a large appliance turns on
- A panel that feels warm, buzzes, or smells like hot plastic
- Outlets or switches that are warm, scorched, or no longer hold a plug tightly
- A panel that’s full, with little or no room for new breakers
- An older panel style that electricians and home inspectors often flag, including Federal Pacific (Stab-Lok) and Zinsco
- Plans to add load: a Level 2 EV charger, a pool or spa, a casita, or a kitchen remodel
One sign alone doesn’t always mean you need a bigger panel. Sometimes a bad breaker, a loose connection, or a dedicated circuit for one new load is enough. We start with an inspection and a load calculation so the recommendation matches your house, not a guess.
For a closer look at what we check inside the cover, see our electrical panel inspection guide.
Do I need a bigger panel for an EV charger, pool, or remodel?
Not always. Before we recommend an upgrade, we run a load calculation that accounts for your AC, range, dryer, water heater, pool equipment, and everyday circuits, then see how much spare capacity is left.
Depending on the numbers, the plan may be:
- A new dedicated circuit on the existing panel
- A power-monitoring, load-managing EV charger when charging is what you’re adding and capacity is tight (Randy’s usual recommendation in that case)
- A subpanel for a casita, shop, or pool pad
- A panel replacement at the same service size, if the enclosure or breakers are the problem
- A service and panel upgrade when the home truly needs more capacity
Homes in Queen Creek and San Tan Valley often sit on newer tract panels that were sized before EV chargers and pools were common. Older Mesa, Tempe, and Chandler homes can have smaller services that need a closer look. Either way, we size the work to what you’re adding—not to a one-size-fits-all amperage.

Who handles the SRP or APS shutoff?
We do. When a panel or service upgrade needs the power cut at the meter, Henderson’s Electric Solutions schedules the disconnect and reconnect with SRP or APS. You don’t have to call the utility yourself or wait on hold for a window that doesn’t match the crew.
Randy Henderson is our licensed electrician (Arizona ROC CR-11 #341452), and he’s responsible for the work on every job. We usually install Square D or Eaton panels and materials.
Does a panel upgrade need a permit?
Yes, a panel upgrade or service change generally needs a permit and inspection in East Valley cities and counties. We pull the permit where one is required, meet the inspector, and leave the work ready for final approval. On projects run by a general contractor, the GC usually holds the permit and we work under their plan.
Current electrical code calls for surge protection whenever a home’s electrical service is installed or replaced, so on a panel or service upgrade we build whole-home surge protection into the plan.
What brands do you install?
We usually install Square D or Eaton panels and materials. Exact breaker types and enclosure size depend on your service, the utility requirements, and what the load calculation calls for. Ask us for our license number and insurance certificate anytime you want them on file.
Frequently asked questions
How do I know if my home needs an electrical panel upgrade?
Your home may need one if breakers trip often, lights dim under big loads, the panel feels warm or buzzes, the panel is full, an inspector flagged an older style such as Federal Pacific (Stab-Lok) or Zinsco, or you’re adding an EV charger, pool, or remodel. A load calculation confirms whether an upgrade or a simpler fix is right.
Can a load-managing EV charger help me skip a panel upgrade?
Sometimes. When capacity is tight and charging is the new load, Randy often recommends a power-monitoring, load-managing charger that shares capacity with the rest of the house. A load calculation tells you whether that’s enough or whether the panel still needs to change.
Will you coordinate the power shutoff with SRP or APS?
Yes. For panel and service work that needs the meter shut off, we schedule the disconnect and reconnect with your utility.
Do you pull the permit for a panel upgrade?
Yes, wherever one is required. On general contractor jobs, the GC usually holds the permit.
Is Federal Pacific or Zinsco always a reason to replace the panel?
Those panel styles are ones electricians and home inspectors often flag because breakers may not trip reliably. We inspect what’s on site and recommend repair or replacement based on condition—not a blanket claim. You can look up specific products on the U.S. Consumer Product Safety Commission site.
