Great service! Rayan made sure to explain what he was doing and why, he is very nice and patient with all the questions we had. The work was done the same day and they made sure to leave everything clean afterwards. Reasonable price after checking with other companies.

Mister Sparky replaced my breaker panel, and did an outstanding job. Carnell did the installation, and I highly recommend him. He was pleasant and very knowledgeable. The City inspector who inspected Carnell's work said that everything was absolutely perfect, and that he wished all work would be done that way. I am confident that my home's electrical system is now very safe, and I appreciate the great job that Carnell did at my home.

The tech was knowledgeable and did inform me of the issue - great. However, this company overcharges ridiculously. The tech tested the smoke alarm and it would not go off because it needs new batteries. He then told me he could change them, cool. He showed me the invoice, $175 - to take 15 seconds to change batteries. $700 just to label a breaker box. Also, the tech kept pressuring me to sign with them after I repeatedly told him I needed to talk to my fiancé about the pricing. Take your business elsewhere.
