Arlington’s Go-To Experts for Main Electrical Service Panel Installation

Power your property with safety, confidence, and future-ready efficiency.
Whether you’re renovating your home, adding an EV charger, or just tired of flickering lights and tripping breakers—a modern Main Electrical Service Panel is essential. And in Arlington, no one does it better than McCarthy Electric & Technologies. With over 25 years of trusted electrical expertise and certified technicians, we deliver panel installations that exceed code—and expectations.

What Is a Main Electrical Service Panel—and Why It Matters in Arlington

Your main electrical service panel is the control hub of your entire electrical system. It distributes electricity from the utility company into various circuits throughout your home or business. Also known as the “breaker box,” this panel is vital for:

  • Managing circuit loads

  • Protecting your home from overloads and fires

  • Powering high-demand appliances like air conditioners, EV chargers, and hot tubs

  • Ensuring safety and code compliance

In Arlington—where older homes, rural properties, and growing families are common—many service panels are outdated or undersized. If your panel is more than 20 years old, or you’re noticing dimming lights, flickering outlets, or constant breaker trips, it might be time for a professional assessment.

The McCarthy Process: Seamless Main Electrical Panel Installation in Arlington

We take pride in delivering a clean, efficient, and transparent installation experience for every Arlington resident. Our process is designed to give you confidence at every step:

1. Consultation & Load Evaluation

We begin with a free estimate and onsite visit, where our technician evaluates your existing panel, electrical usage, and future plans (e.g., adding a hot tub, EV, or kitchen remodel). We perform a formal load calculation, required for any serious upgrade, to determine the right amperage for your needs.

2. Customized Panel Upgrade Plan

Whether you need a 200-amp panel for your growing household or a smart panel that gives you app-based control and energy tracking, we walk you through every option—without upselling what you don’t need.

3. Permitting & Code Compliance

We handle all the necessary permits with the City of Arlington and Snohomish County. Our installations not only meet but exceed state and local code requirements, ensuring safety and long-term value.

4. Professional Installation

Our certified team arrives on time, respects your property, and executes the installation with precision. We specialize in minimizing drywall or structural disruption, leaving your home clean and intact.

5. Testing & Safety Verification

Once installed, we conduct a full system inspection—checking grounding, breaker integrity, and load balance. We walk you through your new panel, label everything clearly, and ensure you feel empowered to manage your system.

6. Support That Doesn’t End at Installation

We offer 24/7 support, emergency service, and extended warranties. You’re not just a project to us—you’re a neighbor. And your safety is our top priority.

Signs You Need a New Service Panel

  • Flickering or dimming lights when major appliances run

  • A panel that’s over 20 years old (especially if it’s Federal Pacific or Zinsco)

  • Melted wires or a burning smell

  • Inability to add circuits for hot tubs, EV chargers, or new appliances

Don’t wait until it’s too late. A faulty panel can lead to fire hazards, property damage, or injury. Let our team evaluate it before small issues become big problems.
