Swartz Diesel is a rarity in modern times. Don and Chris run a business the old fashioned way, with honesty and first class, highly technical knowledge about Diesel repair. Theyre very pleasant to work with and they provide excellent customer service. I felt like I was dealing with friends though we just met.

Great service! Friendly people! Recommend them always!

Very informative and takes care of his customers

Our go to fuel service as the largest commercial Solar company in southern California!

Incompetent mechanic, be careful with them. They overcharge and way under deliver. I’m surprised they are even still in business. You’re better off with Walmart in comparison of detailed engine work.

Took it in for an issue. Paid an absurd amount to have it fixed (enouygh to buy a decent used car. They returned it with the same issue. Then ignored my calls for weeks.

HORRIBLE service this guy told me it would be $3528.00 to replace my turbo the day I went and picked it up the price went up to $4900.00!!! I argued with the man for 30 minutes, telling him I never agreed to an additional amount And that I didn’t have that much money. He then told me he was going to take parts off my truck that would void the warranty on my turbo. But it was the only way the price was coming down. So he did he took to filters off the truck and than said it would void the warranty but he doesn’t do work for free. At that point he lowered the price to $4216.19.which is still $700 more than the original price quoted for turbo but now my warranty on the turbo is void. To top it all off the guy lost my key fob in his shop had to have another one programmed, so someone there has a key to get into my truck. Scam artists for sure!!!!

Called to have my vehicle worked on and he said there is easier work out there and he didnt have time for it!

Swartz Diesel is the place to go in Nevada County. Theyll take excellent care of you!
