Electrical Panel Services in Las Vegas & Henderson

What Electrical Panel Services Cover

Electrical panel services cover everything involved in delivering safe, reliable power from your utility service into your home or business — the main panel, breakers, sub-panels, service capacity, and the wiring connections that feed your circuits. In Las Vegas and Henderson, many properties still run on panels and service sizes built for a different era: 100-amp service, fuse boxes, and breaker panels with no room left for modern loads.

Panel work is not one-size-fits-all. A homeowner adding a Level 2 EV charger may need a panel upgrade or a dedicated circuit. A business with a dark channel-letter sign needs sign lighting repair tied back to the panel. A growing family with a new ADU may need a sub-panel fed from the main. An older home with a recalled panel brand needs full replacement — not another patch. Penny Electric handles each scope with licensed electricians, load calculations, permits, and inspection coordination.

In the Las Vegas valley, heat loads matter: central air conditioning, pool pumps, and tankless water heaters all draw significant amperage at startup. Henderson and Summerlin homes built in the 1980s and 1990s frequently arrive at our assessment with 100-amp panels already at capacity before the first EV charger or kitchen remodel is even planned. Service upgrades to 200-amp capacity and smart panel options like Span are increasingly part of a complete panel strategy — not luxury add-ons.

Whether you need a targeted breaker repair, a sub-panel for a garage workshop, a full panel replacement for an obsolete brand, or a service heavy-up before solar and battery backup, the right first step is an honest assessment by a licensed contractor who will not upsell scope you do not need.

Because panel and service work sits upstream of everything else — HVAC, kitchen appliances, pool equipment, solar, battery backup, and EV charging — getting the panel right is the foundation for every other electrical upgrade. That is why we treat panel services as a distinct category with dedicated specialists, not as an afterthought on a general service call.

Signs Your Panel Needs Attention

Not every electrical problem starts at the panel — but many do, and the signs are easy to miss until something fails completely. Breakers that trip every time the air conditioner starts, lights that dim when the dryer kicks on, or a panel that feels warm to the touch are all signals that demand is exceeding safe capacity or that components inside the panel are failing.

Other signs are more urgent: a burning smell at the breaker box, scorch marks on breakers, buzzing or crackling from inside the panel, or breakers that will not stay reset. These are fire-risk warnings — not inconveniences. If you have a fuse box, an obsolete panel brand, or a panel that an insurer has flagged, replacement may be required before you can renew coverage or pass an inspection.

Planning ahead matters too. If you are adding solar, a Tesla Powerwall, a Span smart panel, an EV charger, a tankless water heater, or a home addition, your existing panel and service size should be evaluated before those projects start — not after a failed inspection or a tripped main breaker mid-install.

Penny Electric serves homeowners and businesses across Las Vegas, Henderson, Summerlin, Green Valley, and the broader valley. Every panel project starts with a load assessment and ends with permitted, inspected work — because the panel is not where you cut corners.

Choosing the Right Panel Service

Homeowners often ask whether they need a panel upgrade, a panel replacement, or a full service upgrade. The answer depends on what is actually limiting your power: an obsolete or damaged panel, insufficient breaker spaces, or total service amperage that cannot support your load. Upgrading breakers inside a 100-amp service will not help if the main disconnect is already maxed when the AC and oven run together.

Sub-panel installation solves a different problem — distributing power to a remote area like a garage or ADU — without necessarily increasing total home capacity. Circuit breaker repair addresses a failing breaker or wiring fault when the panel itself is sound. Span smart panel installation replaces the entire panel with an app-controlled unit for monitoring and backup prioritization — a different outcome than a standard capacity upgrade.

Our job is to match the scope to the problem. If a $300 breaker replacement fixes the issue, that is what we recommend. If your panel brand is on an insurer's watch list, we will tell you replacement is the safe path. If your EV charger project requires 200-amp service, we will quote the heavy-up before the charger install — not after a failed inspection. Explore each service below for details, pricing approach, and FAQs specific to that scope.

Penny Electric has served Las Vegas and Henderson since 2008 as a family-owned licensed electrical contractor (NV C-2 #74758). Panel and service work is a core part of what we do — not a sideline. We carry a $950,000 bid limit, which means we can handle everything from a single breaker replacement to a full 200-amp service upgrade with utility coordination, permits, and final inspection.

Every panel project includes upfront pricing after an on-site assessment. We do not start work without a clear quote, and we do not recommend scope you do not need. That approach is why our customers leave us 4.9-star reviews across 671 verified jobs — honest assessment, permitted work, and a panel you can trust for the next twenty years of upgrades.
