"Very pleased with quality, promptness following schedule, and care taken not to damage hosta plants in the construction area to install 18 kw whole home generator and transfer switch. The project went smoothly in spite of a one day rain delay. The generator and transfer switch were tested with a simulated loss of utility power and everything worked as expected - generator started and transfer switch allowed the generator to power the house automatically. When utility power was reenabled the transfer switch moved back to utility power position and the generator shut down. The price was fair and would certainly have no reservations to recommend them for any electrical work and would use them again."

"Current Electric helped us tremendously with our Electrical Box upgrade. We first wanted our power line to be placed underground and Current Electric helped us with the logistics with contacting the electric company. Second, when it was time for the installation to happen, the technicians came on time, worked diligently, and cleaned up after the project was completed. I would hire them for any of our future projects."

"This is the first time I used Mr. Sparky, and they will definitely be my new go to electricians! I love that they are a small locally owned business! I called about a small non-urgent project, and they were able to come the same day, despite being backed up due to many local flooding issues. Kasey was extremely friendly and helpful on the phone and communication was excellent from start to finish. James showed up on time and was very sweet, yet professional, and my cats even loved him :) He was respectful of me and my property, and took care of my issue in no time. The price was very reasonable! I will definitely call them again, and would highly recommend!"

"Jim was very fast at coming to evaluate what we all needed to have done. He did a great job and cleaned up after he was finished. While he was here we had an issue come up for another electrical problem and he ordered the part and came back as soon as he got the part. Will definitely hire him again when we need electrical work."
