Prompt, Professional Pro's at a fair price !!! Robert Thompson2025-02-02Trustindex verifies that the original source of the review is Google. Harmony electric has now successfully installed the electrical for my hot tub when we bought it and when we moved it to our new home. Both times I was extremely impressed with Pricing: Randy undercut multiple offers by a long shot with superior service. I have seen other hot tub installs that cut corners, not these guys. Upfront billing, no surprises, no upcharging. Communication: Randy explained the whole process with both houses and what was needed from an electrical standpoint. Reliability: I know I can count on Harmony and they will be there when we need them. For example, our family was ill the day of the electric install so Blake came out to hook up the tub the day it was delivered to make sure there was no freezing or issues with it sitting unplugged. Product/Service: Harmony uses superior metal/waterproof piping all along the house over contours and locked into place. Other installs I have seen use flimsy plastic or don’t cover the wire leading up to the tub. That’s a no go and a hazard to my family I don’t want to risk. Follow-Through: Blake showed me through the whole install when it was finished and even buttoned up my old power box that had lost its screws. Stop looking and go with Harmony for any of your electric needs! Jim Minton2025-01-31Trustindex verifies that the original source of the review is Google. I contacted Harmony Electric in the evening using the scheduling feature on their website. I was requesting a repair to the service panel wiring for the air conditioner. Randy called me promptly the following morning with a very reasonable quote and a commitment to perform the work that afternoon. Job well done at a great price. Problem solved thanks to Harmony Electric! Ryan Hawes2025-01-29Trustindex verifies that the original source of the review is Google. Harmony Electric was recommended by Colorado Custom Spas to install our circuit for the spa. In addition to the spa, they moved breakers to the subpanel to make room for the hot tub breaker and also ran a new circuit for the shed. They did a great job, had it all done in half a day and were great to work with right from getting the quote, scheduling the day of the spa delivery and getting the job done.

Randy came recommended from Colorado Custom Spas to help install our new hot tub, and he delivered. He is responsive, prompt, knowledgeable, and has fair pricing; everything you could hope for in a contractor. He braved bad weather on the day of our delivery in order to ensure our hot tub set up went smoothly and got the job done. I plan to use him for all future electrical needs.
