I recently hired Sherwonto Electric for a panel upgrade and EV charger installation, and I’m very happy with the work.

The entire process was smooth from start to finish. They were professional, knowledgeable, and very organized. The panel upgrade was done cleanly and safely, and the EV charger installation works perfectly.

They explained everything clearly, arrived on time, and kept the workspace tidy. You can tell they take pride in their work and follow proper electrical standards.

I would definitely recommend Sherwonto Electric to anyone looking for electrical work, especially panel upgrades or EV charger installations. Great experience overall. 👍
