 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
