I've never had a quicker smog check ever. 15 minutes in and out. Passed and certificate sent. I always come here for my 2 vehicles and the experience is the same. Quick and painless. read more

Two customers ahead of me when I arrived, so waited 5 minutes to process my work order. Two cars ahead of me, so waited 15 minutes to take in my car. Once the car was serviced, it took 5 minutes to complete the smog check process. It was a total of 25 minutes, which was very efficient considering 2 customers were ahead of me. Additionally, there was a $20 discount for mentioning Yelp, so even the price was exceptional. This was my 2nd time taking my car here for smog, and I will continue to come back. read more

I have been coming to this place for a while. Service is always good. Will continue to come here for future smog test.

This has to be the easiest smog check process I have ever had. The staff kept me informed of issues I had and gave me a thorough breakdown on possible future problems. They go beyond my past experiences with smog businesses. I will be bringing my cars here in the future. Great job west valley smog! read more

First time taking my car in for a smog, my husband usually takes care of these things. My registration was late and I only had 2 days to take care of it. I don't know where my husband goes but looked online I saw such great reviews for here. Wow, I don't know what hit me. Drove in, the receptionist took my registration and told me how much it would be. She asked how I heard about them and I said yelp and she took 20.00 off! Mechanic took my car, the receptionist said my car passed, rang me up, got my registration and tags and I'm done and across the street for a oil change. I'll always come here for all 5 of our cars. Thank you West Valley Smog! read more

I was visiting my friend in this area and decided to get my registration out of the way since I was early, and Natasha assisted me. I couldn't believe how quickly everything was done and not even expensive at all for the convenience. She was very enjoyable to work with and despite this location being a bit out of my way, I'll make the trip just because I trust the people there to take care of us. Thanks Natasha!

Great experience at West Valley Smog! Nothing but good things to say! Good: + Very friendly. Over the phone and in person. + Good prices and very competitive. They have coupons available in the mail and on Yelp so be sure to get those. When I was there a customer called in and needed a smog, but said the price was too high for her budget. The guy on the phone was kind enough to drop the price down without asking her for a coupon (same price as with a coupon). That's honest business. + Inside, the business was clean, comfortable, cool and had dart board for customers to kill some time. + For a small fee, they can also renew your car's registration. Save time from going to the DMV. It's worth the nominal fee. I highly recommend WVS based on the great experience I had. read more

Great group of people working here, needed a smog check done quick to make it to DMV before they closed and they got me in and out in record time..didn't sit for more than 5 minutes AND made it to the DMV to get my title transferred.

I'll be back every time I need to smog and highly recommend this place to anyone who's in need of a smog check! read more

Long story short, my registration renewal forms got mailed elsewhere and I never filled out a change of address with the DMV because I totally forgot. Called earlier in the day to see if we can do a smog check and registration without papers and you can! Johnathan helped us as we came in and we were seriously in and out in less than 10 minutes even though we were a walk in appointment (on a Saturday morning). Smog done, registration paid, and I got my stickers! He even changed my address for me and sent that to the DMV. I get why they have 5 stars on yelp. This place is amazing. I will refer this place to everyone I know. Thank you guys for the great service and experience! read more
