This company was assigned to me by Fidelity Home Warranty. Ethan came out and within seconds said my electric problem was not covered by the warranty. He then asked for money to assure my follow up appointment to fix the problem. He sent out two guys that searched around the attic and crawl space. After running up more than a thousand dollars of charges they said they fixed it. After I paid within a day the problem reappeared. When I asked for a refund they blocked me.

I asked Fidelity to send out another company and that electrician said the problem was covered and he fixed it in five minutes.

When you read this Ethan, send me a refund.

My home warranty company used this company. Not only were they able to repair my electrical system they were also able to recommend and repair issues that I wasn't aware of. I could have had an electrical fire, thanks for their knowledge and work I have no more problems. Yes will use again with or without my home warranty.

Came out to the house on a potential home warranty repair. Confirm repair type wouldn't be covered but they did offer competitive pricing as I wanted to replace the fan to the attic anyway. No complaints

One And Only Electrical Service are super awesome. When I called they fit me in for an appointment the same day . Mike installed a ceiling fan for me. When the fan I bought had some issues he went above and beyond to make sure everything was in great working order. Mike was really knowledgeable and efficient! I would definitely use this company again!

The guys did a great job considering there was an issue with the 2nd bedroom. He was able to fix and it looks great. They were quick and efficient. They covered all the areas while working. Once completed they showed me how to use the new fans. Thanks so much!

I called one and only which is a licensed electrician, when I made the appointment I specifically asked for the licensed electrican to come and do the work. I received two guys that didn't speak English and pulled up in a low riding honda with a monster face on the outside. At first he didn't have booties to cover his shoes but they he went back to his car and got them. They needed to install 3 lights, which they did. However they broke my old lightening fixture while taking it down and the glass smashed on the ground. They were responsive and quick with making the appointments but when I reviewed my complaints the office person apologized but sounded like she really didn't care at all. I had to pay $175 for each light fixtures.
