How do I know if my electrical panel needs to be upgraded?

Signs include frequent breaker trips, flickering lights, a burning smell, or if the panel is over 25 years old or uses fuses instead of breakers.

How long does a panel upgrade take?

Most residential panel upgrades can be completed in 4-8 hours, though larger or more complex installations may take longer.

Will I need a permit for panel work?

Yes, electrical panel work typically requires permits and inspections to ensure safety and code compliance.

Can I add more circuits to my existing panel?

It depends on the panel's capacity and available space for additional breakers.

What's the difference between 100-amp and 200-amp service?

200-amp service provides more capacity for modern homes with multiple appliances, HVAC systems, and potential EV chargers.

How do I know if my electrical panel needs to be replaced?

Your panel may need replacement if you have recurring breaker trips, flickering or dimming lights, burning odors, buzzing sounds, visible corrosion or scorch marks, insufficient breaker space, or an outdated panel model. A licensed electrician can assess the panel’s condition, capacity, grounding, and safety features to determine whether repair or replacement is needed.

Should I upgrade from a 100-amp to a 200-amp electrical panel?

A 200-amp upgrade may be recommended when your home’s electrical demand exceeds the capacity of an existing 100-amp panel. Common reasons include adding an EV charger, pool or hot-tub equipment, a larger HVAC system, an induction range, a workshop, solar equipment, or a home addition. Load calculations help determine the right panel size for your household.

How much does it cost to replace an electrical breaker panel?

Panel replacement costs depend on the panel size, current wiring and grounding condition, number of circuits, required permits, equipment selection, and whether the project includes service upgrades, rewiring, surge protection, or added circuits. Trust Point provides an upfront quote after evaluating your home and offers flexible financing options for qualifying projects.

Why does my circuit breaker keep tripping?

A breaker can trip because a circuit is overloaded, an appliance is drawing too much power, wiring is damaged, a short circuit is present, or the breaker itself is failing. Avoid repeatedly resetting a breaker. If it trips again, a licensed electrician should identify and correct the underlying issue.

Are Zinsco or Challenger electrical panels unsafe?

Some older Zinsco and Challenger panel models have known safety concerns and may warrant professional evaluation, particularly if they show damage, overheating, corrosion, or unreliable breaker operation. An electrician can identify the panel type, inspect its condition, and recommend the safest repair or replacement option for your Phoenix-area home.

Why do my breakers keep tripping?

Repeated tripping usually points to an overloaded circuit, a worn breaker, or wiring that wasn't designed for today's loads, common in older Phoenix-area homes running modern AC, appliances, and electronics. A proper diagnosis identifies the actual cause so the fix lasts, rather than resetting the symptom.

Why do my lights flicker or outlets stop working?

Occasional brief dimming when large equipment starts can be normal, but persistent flickering or dead outlets often trace to loose connections, aging components, or circuit capacity issues. Because we service both electrical and HVAC, we can identify whether the cause is in your wiring or your cooling equipment in one visit.

When should I consider a panel upgrade?

Signs include frequent breaker trips, limited capacity for an EV charger or new AC, an older fuse box or sub-100-amp panel, and warmth or buzzing at the panel. An evaluation of your home's existing capacity tells you whether an upgrade is genuinely needed, we'll give you an honest recommendation and an upfront price.

When Do You Need a Panel and Breaker Upgrade?

If you fall under any of the following categories, you may need a panel and breaker upgrade:

You’re experiencing electrical issues: Flickering or dimming lights, distinct burning smells, buzzing sounds, or scorch marks near your panel may indicate an electrical issue.
You’re planning home improvements: If you’re planning a major upgrade, such as installing an EV charger, hot tub, pool equipment, or an HVAC system that requires more amperage, your Phoenix home may need an electrical panel upgrade.
You’re buying or selling a property: Your home systems need to meet current electrical codes to complete the sale and purchase of a home. If an electrical inspection report flags the home’s electrical panel as outdated, unsafe, or noncompliant, a replacement is the next best step. In addition to electrical panel replacement or upgrade, a full home rewiring may be necessary for maximum safety and code compliance.
