Frequently Asked Questions

How much does it cost to replace an electrical panel?

The cost varies depending on the size of the panel and the complexity of the job. Harmony Electric provides free estimates tailored to your specific needs.

How do I know if my panel is outdated?

Panels older than 25 years, or those that frequently trip breakers, overheat, or have safety recalls (e.g., Federal Pacific or Zinsco panels), likely need replacement.

Can my electrical panel support modern appliances?

If you’ve recently added high-demand appliances like EV chargers, HVAC systems, or hot tubs, your current panel may not have the capacity. Upgrading ensures your system can handle the load.

Do I need a permit to replace my electrical panel?

Yes, permits are required for electrical panel replacements. Harmony Electric handles the permitting process to ensure compliance with local regulations.

How long does an electrical panel upgrade take?

Most panel upgrades are completed within one day, although the timeline can vary depending on the complexity of the project.

What’s the difference between a fuse box and a breaker panel?

Fuse boxes are older systems that use fuses to protect circuits, whereas breaker panels use circuit breakers. Breaker panels are safer, easier to use, and more compatible with modern electrical demands.
