Edison is great! He has taken the time to walk us through our generator options and installation process. Always returned calls and emails. I dont believe half of the reviews on here.

Didn't use them, but they gave me a call back almost immediately and were very polite and helpful.

Absolutely on point and professional! We had lost power to our home do to a problem in the main electrical panel, and Edison and Russ responded very well to our needs. They had already fixed our generator so it was reliable to provide us with back up power in the interim keeping my grandfathers oxygen machine working. Not the cheapest outfit in town, but I am a firm believer that you get what you pay for.

Edison of High Sierra Electric installed our stand-by home generator and automatic transfer switch years ago. The system has worked flawlessly through many power failures and the High Sierra crew continues to perform all scheduled maintenance. I recommend High Sierra Electric without reservation.

Edison, owner of High Sierra Electric is awesome. He has come to our rescue more than once at our home and he has always been very professional and very efficient!
I believe he now specializes in generators. He would be the first business we would go to if we were in need of such work.
Very ethical - deserves nothing less than five stars!

The folks here were wonderful! They TOTALY went above and beyond to fix my electrical problems and my generator in my motor home van. And the personal customer service is the best. I depend on my van for work in the Bay Area on the weekdays and the generator was dead and there was several power drains that NOBODY could find (myself included). This made the van unuseagble. So, my wife went to drive it over there and it broke down on the side of the road. She called to cancel the appointment and they offered to drive over to troubleshoot it or work with the towing agency to get it over there (she actually just ran out of gas and needed to switch the tanks). Once we got it there, they tracked down the power drains and checked in with us every step of the way constantly letting us know how much time was into it and how far they got. I know my way around electrical so they kept explaining exactly what they where going to do and provided me with the option to do certain simple things myself if I so desired (put in a terminal, etc). What I liked is that they looked at it from a customer spending/function standpoint. This van is old and has had a LOT of tinkerers wire in all kinds of things over the years so frankly it was a mess electronically. I really didn't think anyone would take on the job frankly. They focused on the cost and prioritized according to my needs. When it came to the generator, it had several things wrong (switches that were cracked and broken, rotten filters, a fried circuit board, carb gummed up, etc.). Then, knowing I really need it on the weekdays, they arranged their technicians to be there on the weekends. Sure enough, by Saturday afternoon, they had it all ready to go, installed it - all done! They walked me through what they did, how to care for the generator, maintenance, operations, the works. Throughout all the work, I never had to shell out money for a hotel because I was able to use the van every weekday thanks to the fact that they worked around my schedule. The van is like a new motor home to me. No draining batteries. Generator starts right up purrs like a kitten so now everything works (air conditioner, micro wave, etc.). A week later I even got a follow up call. They wanted to check up on their work to make sure it wasn't draining down anymore and it was working as designed! Shops like this is why I live in Nevada County!

Absolute Crook. Took my brand new rv in to have them look at the generator that was acting up based on DeMartini RV sending me there. So many things went wrong but the main thing was that he supposedly did 650.00 worth of work to a generator that was running. We never got a quote from him and he just replaced the fuel pump, hoses etc. We never got an oral estimate he just did the work and held our rv for ransom...nor did we get the used parts back when we asked for them and the generator pretty much works the same. He says he spent 6 hours on the generator which I find very hard to believe.
Even worst...He did the work on Monday...I had to call on Tuesday to find out what he discovered might be wrong. He called back two hours later demanding payment of 650.00.
Then we simply wanted to call the Dealer on a new rig who sent us to him to find out if they were paying for it or if I was. It was literally hours after the job was complete and he would not stop harassing us for payment.
Simply put...I doubt he even did any work and he threatened to lock up our rig for two weeks if we didn't pay him way too much money that he did not quote us for.
The other thing is we caught him lying about many things including he said the dealer told him they weren't covering it....Which was totally untrue because I was in the dealers office the only time they spoke and the dealer told him they were submitting the bill to the builder of the RV.

Their trouble shooting process is to simply replace everything! VERY expensive. When my RV was returned they had failed to recognize that once they had opened the propane line all of the gas fired stove, refrigerator and water heater would not work without bleeding. They never checked them and did not care when I called it to their attention! VERY crappy service- will for sure tell all my friends to never use these guys!

These guys came out to service my Kohler generator for a specific problem. They charged me around $300 for a standard service check but did not remedy the problem. I called and talked to the owner and told him that the service techs knew ahead of time why they were coming out but instead of addressing the specific issue they simply performed a routine maintenance service. He said he was not responsible. They didn't even notice that one exhaust pipe looked completely new (paint not burned off on an 8 year old genny? Hello!) and that this would indicate the generator was running on only one cylinder. When asked about this, the owner said it probably needed a valve adjustment. My Kohler doesn't have adjustable valves you muttonhead. When I brought up the idea of providing quality service as good business practice the owner replied, ""Are you threatening me?"" Woah! Steer clear of these kooks.

I have a Kohler generator which had failed. I called High Sierra looking for the part.
The person who took my call, took all of the information needed to be able to order my part.
One week later when I still had not heard from them, I called back, only to find out they don't sell parts.
Why couldn't their employee tell me this when I first called.
Talk about VERY LOUSY customer service.
Anyone doing business with them is a fool.
You have been warned.
