Posted on Google Mark EarlyTrustindex verifies that the original source of the review is Google. I worked with Randy, Blake and Logan for the electrical installation of my hot tub. I can’t say enough about how thorough and professional those guys are. The communication was outstanding the quality of their work was even better. I’m definitely going to use those guys again for some electrical upgrades in my garage. 5 stars for sure and would have give 10 stars if it was an option. Thanks guys for a great experience! Mark EarlyPosted on Google Ben HranchakTrustindex 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 recommendPosted on Google Eric MiyazawaTrustindex verifies that the original source of the review is Google. Randy showed a lot of patience and persistence working with the power company and county to complete what we needed done.Posted on Google Shane BussartTrustindex verifies that the original source of the review is Google. Very good job on a 50 amp GFI for our new spa!Posted on Google Jared MckennyTrustindex verifies that the original source of the review is Google. These guys do it right. If you are looking for an electrician that pays serious attention to detail Randy is your man!Posted on Google Tammy TallentTrustindex verifies that the original source of the review is Google. We needed our new hot tub wired up. Randy came out and walked the install. Got an estimate the next morning. Price was super competitive and they were ready to install in a day. Great install. Ran the wiring from the front of the house to the back through the crawl space. Not fun but they did a great job and performed the install in 3 hours. Full warranty of their work for the life of the hot tub. Not sure if anyone offers that. I highly recommend Harmony Electric for anything electrical.Posted on Google Elise McIntireTrustindex verifies that the original source of the review is Google. This company is the best! Randy is thorough, honest, and kind. I sent a request for an outlet that wasn’t working and within hours he was able to come to my home in Parker, CO and help me. He sent me an estimate before coming which is something that I’ve never seen from an electrician. Once Randy got here he found that it was just a breaker that was flipped. I felt very silly for making him come all the way out here for that so I tried to pay him for all the time and gas money he spent coming out here but he wouldn’t accept it. He could have easily charged me the full estimate and I would’ve happily paid it. Bottom line- this company is great and is not looking to make an extra buck by scamming people. I will be calling him for ALL of my future electrical problems!Posted on Google Brandon GoshornTrustindex verifies that the original source of the review is Google. Very pleased with Harmony Electric’s work at my home. Logan and Blake were very knowledgeable and respectful of my home and just good people. They made quick work of the things I needed done. One involved troubleshooting an electric baseboard heater in my garage that could have burned down my house. Luckily they figured that out! They also added new receptacles and some ceiling lights to my unfinished basement area. I’m glad I called these guys! Thanks Randy and the team.Posted on Google SashaTrustindex verifies that the original source of the review is Google. Randy and his team are the best in the business for your electrical needs.
