Had Chasov do several upgrades to our house with lighting and outlets -

Our house was not easy to navigate with minimal attic space and blow in insulation etc

Alex & Harry were a pleasure to deal with - very professional, showed up on time, cleaned up super well after each day

Screws on switch panels were all orientated vertically - details!

Top notch work - highly recommended

I recently got a bid for a project from a different electrical company that I was very unhappy with. Not only was the quote very high, but their suggested approach was extremely complex and would have involved tearing down walls and tearing my yard.

Then I remembered that I'd had a positive experience with Chasov Electric several years ago so I reached out. Michael came out to inspect our property and immediately proposed a much simpler and more cost effective solution. He took photos on his tablet and sent mockups of his proposed design in advance.

Harry and Alex completed the project and they were delightful to work with. They arrived on time, confirmed details and decisions with me throughout the day, and carefully inspected all their work prior to departing. I'm very happy with how the work turned out.

I can't speak highly enough about the professionalism and creativity of Chasov Electric. They are true engineers and ""electrical magicians."" I would definitely recommend them, especially for any projects requiring creative or complex electrical solutions!

Thanks to Michael for rectifying my issues with the previous job very promptly. The huge holes in my bathroom were patched up and the job was finished yesterday. Michael called me for a follow up and gave a very thorough explanation of how jobs, like the one I had, are supposed to be done. For the owner of the company to provide such EXCELLENT customer service/customer recovery is a great reflection of the company. Furthermore, I am using Chasov Electric again for another possible job on the house-depending on how the consultation goes if it needs to be done. THANK YOU. THANK YOU. THANK YOU.

Michael responded to my call same-day and quickly diagnosed the that the problem we had with our lights flickering and furnace not working was on the PG&E line. This allowed me to get PG&E out quickly and even though they didn't believe me at first, turns out Michael was right! Thanks again!

We wanted to post appreciation of Chasov's owner and his referred rep Dmitri Jermoljev. Chasov concentrates on construction jobs, but has resources for residential and homeowners.
They were prompt, good problem solvers, treated us with a well organized approach, presented reasonable solutions and were in the $$ range for professional licensed electricians (versus handyman range, no knock against handypersons).
Initial contact was friendly, professional, low pressure, not distracted, and they were available even though busy elsewhere.

We ended up getting a package from our neighbor's contractor (all crew are on site this month - carpentry, tile, electrical, plumber), for several services we needed last minute. Chasov presented a trustworthy, responsive contact in all our interactions which is why we're posting here.

Main point: Both Chasov and Dmitri were good communicators, presented solutions clearly and were familiar with and had confidence in handling issues any homeowner of a San Francisco has to contend with due to the mix of contractor and vendor skill levels out there.
Check the other positive reviews and consider them.
Thanks Dmitri and Michael Chasov!

Love this place! I have used them twice for electrical issues in my condo. They are very responsive! Dmitri was scheduled to come over. He was very prompt. He's friendly and very knowledgeable. The repair required a new part and that part was obsolete. They found a replacement part and notified me when it was in. The actual repair was done in a short time. Excellent customer service!

Michael is a genius. Pure and simple. He helped diagnose an electrical wiring problem between my condo and my neighbor's condo that was in existence since the place was built 35 years ago.

Very professional, direct, and honest.

I wish all contractors I hired were of this caliber!

Had an emergency repair for outside light fixture. They were fast and charged a very reasonable fee. I would use them again for electrical work for sure.

I interviewed three electrical contractors to upgrade the circuitry in my San Francisco row house. Michael Chasov was the last. He was the only 'diamond certified' contractor of the three, and his web site was much more polished and professional than that of the others - for whatever that's worth, as a nice web site design hardly guarantees a good contractor.

I felt just a bit nervous about hiring him. Michael is a fluent English speaker, but English isn't his native language, and I fretted about a couple of small miscommunications during our consultation. I would be contracting with him for critical electric circuitry; any potential for misunderstanding worried me. But he was so obviously sharp that I decided to push these concerns aside, and am now quite glad I did.

The crew arrived at 8:00 on the dot and finished earlier than expected. I can't judge their work as an electrical expert could, but, for what it's worth: I was impressed by every aspect of what they did in my home. Their installation of the new wiring was much more thorough than I expected, and Victor did a terrific job of explaining the scope of the work after they were through.

The full name of the company is 'Chasov Electrical, Voice & Data.' Michael seemed thoroughly familiar with the internet plumbing required to network a home; he might be an excellent contractor to work with on such a project.

A circuit went down and resetting the circuit breakers didn't help. I called Chasov and he talked me through two of the things that most commonly go wrong. It was the second, and we have power throughout the house now. Chasov is top of my list now for our upcoming job when we redo our knob and tube!
