Kind, professional and prompt service from Ace Electric! I am working on my mental health and have some anxiety around having others see the extreme clutter in my home. I mentioned this when making appointments with service manager Brandon. Tony and David came out promptly, and they very kindly and efficiently installed all new smoke detectors and inspected all wiring in our attic. Turned out we needed several repairs after damage from squirrels getting in. For the attic repair, Brandon soon emailed us the quote and, again, technicians Conard and Levi were prompt, super nice and professional. They not only made the repairs found in the initial inspection, but they also double-checked everything in case there was any other damage that might have been missed. Thank you so much to all the guys at Ace and to Claudette at their office, who's always so kind and helpful! Highly recommend! ??

Ace came to install electric in a home addition we are working on. They were amazing! Everything looks great and the crew was nice and easy to work with. Thank you!

Christine Albrecht

Our maintenance work with Ace Electric was completed on time and within budget. The technicians, Chad and Nick were efficient, easy to work with, clean and competent. A couple of times we ran into areas where we needed to modify the original plans. Chad was knowledgeable and suggested several options to resolve the situations. He and Nick were willing to do whatever it took to get the job done. We are very satisfied with the work and recommend Ace for future work you may have.

Caroline Sparks

These are our go-to guys for all our electrical needs. Whenever we need them, they are always very professional and knowledgeable and genuinely care about doing a quality and safe job. For our most recent project, we needed a new circuit run and additionally asked if they would put in afci/gfci breakers as an upgrade for our panel. Chad showed up very promptly and did everything we asked, including investigating a shared neutral and fixing it for us. He explained everything he was doing and answered all our questions. We are very happy with the work. 10/10

On the whole, it was a very positive experience. Chad was kind, professional, and knowledgeable. He inspired confidence that I could trust in the work that would be performed. This first service call was a simple light fixture replacement, but the real project will be having my electrical panel upgraded which is the primary reason I needed an electrician. I'm waiting for estimates for that work and don't know yet how to rate Ace in this department, but I can say that the service call charge for today's light fixture work was fair and within my expectations. I'll follow up to edit the review after the big project, but so far, I feel good about choosing Ace!
