 Trustindex verifies that the original source of the review is Google. I had a great experience with Harmony Electric! My house was lacking overhead lighting in all bedrooms, and we wanted an EV charger installed, as well as a few other items. Randy came to the house and thoroughly detailed the work to be done, providing a very reasonable estimate in a timely manner. Randy and his team at Harmony Electric were prompt, professional, and made sure all work was exactly as we wanted. They made sure to clean up after project completion. Excellent work……I would highly recommend Harmony Electric!

 Trustindex verifies that the original source of the review is Google. We recently purchased a new hot tub and were referred to Harmony Electric for the electrical installation. From start to finish, the entire experience was outstanding! Randy responded quickly to our initial inquiry and came to our home to provide a detailed estimate. He took the time to explain everything thoroughly, answered all of our questions, and made the entire process simple and stress-free. On installation day, Blake and Logan arrived right on time and couldn’t have been more professional or pleasant to work with. They did an exceptional job running the electrical for our hot tub and paid close attention to every detail. It was obvious they take great pride in their work and genuinely care about doing the job the right way. Their workmanship was clean, organized, and of the highest quality. It’s refreshing to work with a company that values professionalism, communication, and customer service from beginning to end. We couldn’t be happier with the results and would not hesitate to recommend Harmony Electric to anyone looking for honest, dependable, and high-quality electrical work. Randy, Blake, and Logan were all outstanding, and we truly appreciate the excellent service they provided! ~Bill Taylor

 Trustindex verifies that the original source of the review is Google. Honestly one of the best companies I've ever used. I love how Randy does business. Scheduling was organized, easy and the estimate was fair and didn't change. The guys who showed up were right on time, didn't mess around, knew what they were doing, and we're very professional. It is hard to find younger people who want to work and do a good job. You can tell that they've been trained very well. I will be using them again in a few months. Highly recommend

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.
