    Ceiling fan
    Maira V.

    We cannot express how happy we are with the outcome!! Justin and Dan did a phenomenal job, and took only about an hour to install both fixtures. We inquired with at least 5 other companies but Sigma provided the best value and a free estimate, and I felt the most confident with them given the other reviews. The chandelier was installed at the perfect height, and it's level. The fan is nice and sturdy. They were very thorough in ensuring everything worked and did not rush. We'll definitely be calling them again for our electrical work! Thank you!

    Installed all this! In a day!

    Our house is 22 years old and has fixtures to match. We contacted Sigma to do the installation of all new fixtures (4 bath lights, 3 fans, and a chandelier). Got a too low price on the install based on the amount of time and the complete rewiring necessary for two of the fans. I felt sorry for the guys, they were there all day and hitting roadblocks. Despite all the extra time and effort that was not accounted for, they STILL honored the original price. These guys worked their butts off for us all day and absolutely put customer service above all else. We couldn't be happier. 10/10. Highly recommend.

    Fast, friendly and professional all around. Highly recommend!! Justin came out to give quick estimate. I wanted a 220V outlet for my Tesla charger. Their pricing was fair and reasonable. Pre paid for permit in advance. Was able to schedule installation within a week. Justin returned to install. Job was done within an hour or so. Cleaned up after themselves and I was able to charge my Tesla immediately.

He completed everything in a timely and efficient manner without cutting corners. He was very respectful of my home, kept the workspace clean, and made sure to tidy up as much as possible before leaving. Although the original invoice didn't include the permit, I asked about it during the job and he was able to add it on the spot. He clearly explained the next steps, including how the inspection process would work (either in person or by video), which gave me peace of mind. It's been a few days now, and everything is working perfectly. The installation looks clean and professionally done. I truly appreciate his attention to detail, communication, and professionalism. He came back a week later to drop off the permit. I would absolutely recommend Christian to anyone needing electrical work.

    Experiencing a major electrical failure on Memorial Day was an absolute Nevada homeowner nightmare…read more Our main power box failed unexpectedly, and like most people would expect on a holiday, I couldn't get a single electrician to answer the phone. Understandable, but still incredibly stressful when you're suddenly without power. Ampere Electric was the exception. Not only did they answer the phone, they had someone at my house within an hour. Unfortunately, by the time they arrived it was late in the evening and there wasn't much that could safely be done until NV Energy could disconnect service the next morning. What impressed me was that they didn't make promises they couldn't keep. Instead, they told me exactly what would happen: they would coordinate with NV Energy first thing in the morning, get the power disconnected, and begin work immediately. That's exactly what happened. Patricio and Carlos arrived early and worked hard all day. They replaced the equipment, completed the installation, and had everything finished by around 3 PM. At that point, the only thing left was waiting for NV Energy to return so final restoration could take place. Unfortunately, NV Energy was completely inundated and running far behind schedule. This is where Ampere really separated themselves from every other contractor I've worked with. Patricio and Carlos could have easily packed up, told us we'd have to wait until the next day, and moved on to their next job. Instead, they stayed. They waited outside my house for hours. They repeatedly apologized for the inconvenience even though the delay wasn't their fault in any way. They had done their job and done it well, yet they refused to leave until the entire situation was resolved. NV Energy didn't arrive until nearly 8 PM. Patricio and Carlos were still there. The moment NV Energy completed their portion, they immediately restored everything, verified that power was working properly, and stayed until we were fully situated and every aspect of the job was complete. That level of customer service is rare. They didn't leave us stranded. They didn't pass the problem to someone else. They didn't do the minimum. They saw the job all the way through from start to finish, even when it meant spending their entire day and evening making sure their customers were taken care of. I am incredibly impressed with Ampere Electric, and especially with Patricio and Carlos. If you want a company that does what they say they're going to do, communicates honestly, and treats your problem like it's their problem, this is the team to call. Five stars, without hesitation. I can't thank Patricio and Carlos enough. Seriously.

Didn't do a bad job after the fact, but lost power to all the electrical outlets in one room, and all the power in the other room. I called around for an expert. I thought it might have something to do with the breaker panel. 24-7 lived up to their name as they were able to have someone come out within the hour. A couple of other places didn't have people until two or three days later. Rene showed up. I told him everything I did and after some trial and error, he figured out the problem. I did everything correct, but there was a bad GFCI outlet that I didn't even touch that was stressed out. We ended up replacing it. He fixed it and checked all my work while teaching me about electricity. He was really professional, respectful and a patient teacher. He let me ask all the questions I wanted. He even took off his shoes even when I said it wasn't necessary. If there are future projects where I need a professional, I would definitely call these guys and Rene again. And the work is guaranteed for one year.
