Recently they hired a new tech that has been telling me I need to make an appointment. So I called during the week and was told they never set appointments and "It's first come first serve". It's always been that. I went back again and the tech refused to serve me without an appointment. So I called again. I was told again "first come first serve". So I went back and the tech said no. He said my car takes 45 minutes and Honda and Toyotas only take 15 minutes so her doesn't want to do my car. So I try a third time and he tells me I'm hostile and won't accept my appointment. I am not hostile. Especially if someone is going to put hands on my cars. I will repeat my statement to the tech. A customer should not have to worry how long one vehicle takes over an other. Six days a week the other tech says they have always been first come first serve and customers should be able to expect consistent service. When i asked for the managers name is when the new tech said I was hostile. I called the other Smog Queen locations and they also said, "FIRST COME FIRST SERVE!" It's too bad this tech will lose a VERY LONG term customer I also check the other location and they confirmed they do not make appointments.

* Visited on a Thursday around 11:30am :)…read more I had gotten my car smog here after looking for a nearby star certified station. It was pretty quick and easy- literally finished within 15-20 minutes and that's without an appointment. I believe the pricing was $100 for the smog, but there's a coupon on their site for $30 off- be sure to check out their site. Mind you, it's 1 stall and I came while they weren't busy.

I've been coming here for 8+ years. It's not the most convenient location for me on a weekday, but…read moreit's the best-priced smog shop I've found. For my first appointment this year, I was running quite late. I texted Francis with my updated ETA, and we agreed it made more sense to reschedule. I appreciated the quick responses and easy communication. At my rescheduled appointment, I arrived about 5 minutes early. Appointments were running roughly 10 minutes behind, which wasn't a problem, but it's worth building a little buffer into your schedule just in case. As always, once my car was in, the process was quick and straightforward. I was in and out without any issues. Note: I tried using Yelp's "Project" feature and never received a response. When I contacted the business directly through their website, I received a reply within 24 hours.

I was in and out within 10 minutes, with a paper copy of my certification plus it was submitted to the DMV and showed up online almost immediately. The shop was SUPER clean, the guy running the place (Cesar, I think?) was friendly, fast, and thorough. I cannot recommend this place enough.

Unfortunately had a poor experience here…read more Brought in a manual transmission car from 1986 for a smog check, called beforehand to confirm if they could do it, and they said they were able to. The worker seemed uncomfortable moving my car around since it was a manual. He got it on the dyno and stalled it 3 times while it was on the dyno, so it wasn't a pretty sound each of those times. After the third stall, he said that he couldn't complete the smog because something was broken and not able to connect. Now the worst part was that while he was trying to get it off the dyno, he revved really high and had the clutch midway which essentially burns the clutch. Now we both know that it happened because it smelled like burning clutch, which is pretty distinct. I called the owner and all he could say was that if it drives fine then sorry, but it's fine. They told me to come back another day when the machine actually works. Now I'm left with no smog check, a worse off clutch, and grease marks from the worker's hands on my hood, shift knob, and steering wheel lol.

All I could find were tiny signs marking crowded, tiny shops in crowded, tiny parking lots that gave me a bit of a panic attack. I plugged into Waze, which took me here. Ah, so peaceful! No waiting, no confusing parking lots or ambiguous signs, just a bright flashing sign for smog checks and easy access to where I needed to park. The wait area was an oasis of peace. This will be my go-to now!

The car was pulled in and the back lens covers (which are tinted) were clearly visible. He charged me $180 to do the inspection and said it failed because of the tinted lenses. I said, "you could have told me before you took my money" and he said "this is how I get my business". An up front business would say, "before I take your money, know that this car will not pass". But he is not an up front business. We argued. I felt scammed. He said he wished he never sees me again. That's okay. I give 1 star because I am not going to try to pull my payment.
