Panel Upgrades

Electrical panel upgrades for Arizona homes. Increase your home's capacity, replace outdated panels, and meet modern electrical demands safely.

H&M Electrical performs electrical panel upgrades for Arizona homes, including 100-amp to 200-amp upgrades, obsolete panel replacements, and subpanel installations. A panel upgrade increases your home's electrical capacity to safely support modern appliances, HVAC systems, EV chargers, and other high-demand equipment while meeting current Arizona electrical codes.

When You Need a Panel Upgrade

Your electrical panel is the heart of your home's electrical system. If your panel cannot keep up with your home's demand, you will experience frequently tripped breakers, the inability to add new circuits, and potential safety hazards. Panel upgrades are commonly needed when adding major appliances, installing EV chargers, upgrading HVAC systems, or purchasing a home with an older 100-amp panel that does not meet modern needs.

  • Upgrade from 100-amp to 200-amp service
  • Replace hazardous Federal Pacific, Zinsco, and Pushmatic panels
  • Add subpanels for garages, workshops, and additions
  • Install new panels during home renovations and remodels
  • Bring panels up to current NEC and Arizona code requirements

Hazardous Panel Replacement

Certain panel brands have documented safety issues. Federal Pacific Stab-Lok panels and Zinsco panels have known failure rates that can prevent breakers from tripping during an overload, creating serious fire hazards. If your Arizona home has one of these panels, replacement is strongly recommended regardless of the panel's age. H&M Electrical assesses your existing panel and provides honest guidance on whether replacement is necessary.

The Panel Upgrade Process

A panel upgrade typically involves coordinating with the utility company for a temporary power disconnect, removing the old panel, installing the new panel with updated breakers and wiring, reconnecting all circuits, and restoring power. H&M Electrical handles all permitting, utility coordination, and final inspection. Most residential panel upgrades are completed in one day.

Arizona Expertise

Arizona homes face high electrical demands due to year-round air conditioning. A 100-amp panel that was adequate when the home was built often cannot support modern HVAC systems, EV chargers, and today's appliance loads. Arizona building departments require permits and inspections for panel work, and H&M Electrical handles the full process. Desert heat also accelerates wear on older panel components, making timely upgrades a safety priority.

Our Experience

H&M Electrical has performed panel upgrades across Arizona, from replacing hazardous Federal Pacific panels in older Phoenix neighborhoods to installing 200-amp service in growing Mesa communities. We coordinate with Arizona Public Service and Tucson Electric Power for seamless utility work and handle all permitting and inspections.
