A1 Smog Check *STAR* Station, Livermore CA

I took my car there to be tested, and because I had gotten a new battery, the car did not pass the test because, after a new battery, the car needs to be driven a couple hundred miles. I took it back for a retest, which required an additional cost, and the car passed. The staff was professional and efficient. Just a FYI, if your car just got a new battery, should be aware, which I was not, but you need to drive the car a few hundred miles.

They do an efficient job at a reasonable price. Be aware, their price sign does say that they charge for re-tests. The place is really tucked in the back there (see pic) which also just kind of makes me think it must be a pretty good place. You know, those good quality shops that can't pay premium price for a premium retail location because they don't scam their customers? That kind of place. Staff was super nice. Just walk in (door looks like, "is it a door to the garage? Am I supposed to go in there? " But its the office like a normal place.) Not a ton of parking if you have to wait you should be able to find a few spots right in front of the garage. No appt necessary. Only had to wait like 15min and 1 person ahead of me. Total cost for my car (2 door coupe, nothing fancy,) was $54.75.

This was first ever smog test for my Prius. They were really busy when I came mid-morning in a Wednesday, but he was juggling all of us customers efficiently.

I went on a Monday morning June 2023. Only 1 car ahead of me. The whole process took about 10-15 minutes so was very quick. Their website had a $25 discount (you just had to mention it). The regular price was $69.95. But after the DMV certificate fee $8.25, STAR directed fee $10, and transaction fee $1.75, you only get about $5 discount. So total for my civic was $64.75. Comparable to Vasco Quick Lube smog $66.25 in Jan 2023. I was a little disappointed because I thought I would get a better deal. But the price is fair for the area.

A1 Smog is an honest place to do business. The staff are courteous and very professional! Highly recommend!

I was scheduled to have my 25 ft RV smogged at another place, but their machine was not working. I went to A1 Smog and they took care of me quickly and at a fair price. Excellent service.

They were welcoming. The shop is in the cut if you know what that means. When GPS tells you to take a right. Then look to the right. They are right there. I will go again.

Good pricing and fast service.even with my '96 Dodge Van.highly recommend this place for a smog certification. It's tucked away in the back of some other buildings off the main street, but it's worth the effort to find it. No appointment is needed, but I usually call first.always done in 20-30 minutes max!

Great price, no hassle, straight forward, and they won't upsell you for repairs like other places. My mother went to a place off airway and they tried to scam her for a repair saying the smog check didn't pass. She went to another smog shop and dealership and they said nothing was wrong.

My go to place for smog checks. Good service affordable pricing, and quick even if you're a walk-in.

Very attentive and courteous
to their customer service I will definitely keep coming back to this business

Been taking my cars to this place for many years... The tech/owner is very honest, knowledgeable and helpful to make sure your car passes the smog check without breaking your bank!

I wish i would of know about this place 3 months ago when i had my other car smog’d for $75. I came here today with no appointment and no coupon for a discount. They gave it to me anyway. Only paid $55 And was in and out in 15-20 mins. Cheapest smog in Livermore
