"Devin Dotson, the owner, spent the day at my home installing a new 200 amp electrical panel. I was very impressed with the quality of his work. He did a great job. He was thorough, marked every new fuse and labeled what each one was connected to. Then he tested everything in the house to ensure it was working properly. I couldn't be happier with Current Electric and highly recommend them."

"Great experience. Quick to respond with a quote, very reasonable price, complete and professional service. The three men were very courteous and respectful. They finished in the expected time and left all the work areas very clean. Their offered service was more complete than the other electrical companies we considered; they installed some fixtures that some other highly rated electrical companies declined to handle."

"I'm so glad we went with JM Electric to replace/upgrade our electrical panel. They were fast, efficient, professional, courteous, and above all gave great advice. They even installed my husband's new garage heater after installing the designated electrical wire for it. I have no clue as to what or where the wires go beyond the outlets themselves. I just mentioned what we needed, Josh and Zach explained everything prior and handled everything on installation day. Definitely will be hiring them again if we ever need more electrical work. Thanks again JM Electric! (Josh and Zach)"

"Not an overly fancy outfit but showed up when they said they would, did the job they said they would, and we're very pleasant to work with throughout the project. I would gladly hire again or refer to anyone who needs electrical work."

"They upgraded my electrical panel and was definitely the best quote i received. Charles was polite and picked up on things few other companies were able to. We scheduled and they came in and did the work but the mistake i made was paying in full before the work was 100% complete. It seemed like i was no longer a priority and it took numerous attempts to schedule in a time and more importantly get them to commit to it. It took about a month before the job was finally 100% complete."

"We requested a quote for electrical outlet work on Sunday and received a response via email by Cory on Sunday evening. Scheduled them to come out Monday morning and Chris came out on time and got our dryer up and running within 15 minutes. We had just moved to this home over the weekend and Ultra saved us and they were very reasonable in pricing. We highly recommend this company to perform all your electrical needs."

FAQs for electrical wiring or panel upgrade projects in Denver, CO

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
