My AC went out in this excruciating heat . I dropped it off and Allan fixed it. I am now driving with ice cold air.

This man is not trustworthy or honest he tried to charge me $700 to recharge my air-conditioning unit saying that system had a crack in it. I Took it elsewhere and they told me there was no crack recharged it for $400 read more

My husband usually handles the car stuff so I was grateful that I was able to bring our car here for a smog check without being pressured for extraneous services. He did let me know there was a small gasket leak but said it was not an emergency and he can handle it in the future if I'd like. Was in and out in 25 minutes for the smog check. read more

I trust him with all my family cars. Thanks Mr. Alan for take care all my family cars! read more

WOW! I am impressed!! The AC in my 2007 Honda Civic had stopped working a few weeks ago. I had seen Kool Auto's signs for sometime, saying they work on Acs so when I noticed there were no cars there this morning, I decided to pop in and check them out. Approximately 30 minutes later I am driving home in a cool, air conditioned car!! The AC relay wasn't working properly and my cabin filter was EXTREMELY dirty. Both are good now and the cost for the repair was very reasonable! Yay! Also, the waiting area was a heavily shaded garden. It was so cool and peaceful. I think I have found my new mechanic! Thank you Alan & Kool Auto Service! You totally made my day read more

My 2 tire pressure sensors were broken. Alan diagnosed and fixed the problem effectively. The price was reasonable. read more

I don't usually write reviews, but Alan deserves one! He is all about honest, quality service--no upsells, just what your car truly needs. I brought in our family-prized 1997 Jaguar for basic maintenance, and Alan worked his magic. I'm confident bringing in our other cars, knowing he has his customers' best interests at heart. Definitely reach out ahead of time since he's a one-man show... though with this level of service, that might not be the case for long! Highly recommend! read more

I found this place for my mom, but have ended up going here myself as well. Alan is the most straightforward, down-to-earth, trustworthy mechanic. He doesn't want to keep clients waiting in a queue at the shop, so he asks you to just check in with a quick call, and will give you a good time to come with your vehicle. This alone saved me a 1/2 day or overnight dropoff, which can be such a hindrance when your car needs a repair, and can leave you stranded at other auto shops. His service was fast, friendly, affordable. While I never look forward to car repairs, I now feel I have another reliable support system and would feel safe bringing any of my loved ones' vehicles to Kool Auto Service. Thanks! read more

My truck need brakes and Kool auto did a complete job on all four wheels. New pads, rear rotors and front discs. The next day I began to notice a vibration when applying the brakes. The hotter the brakes got the more vibration. I took it back and the owner/mechanic said the brakes where fine and the reason for the vibration was because the control arms where faulty and need to be replaced. He wanted more $$$$. I did not trust him so after two visits and trying to get him to fix the brakes that were under warranty. I went to another mechanic and explain to him what had happened. He checked it out and said the rotors and discs need to be turned. Problem fixed. I went back to KOOL and forced him to give me a refund. Mr KOOL, I was not looking for perfection I was simply looking for honesty. You say I only went back once. Let me remind you. The first time I went back I told you the brakes didn't feel right and the hotter they got the more vibration I felt on the pedal. You went with me for a test drive. When we got back you lifted the truck on the crane and did not inspect the brakes you just began moving the control arms with a crow bar and tried to convince me that there was the new problem. I returned a week later and told you that the problem was getting worse and asked you to inspect the brakes. You tried to assure me that the problem was the control arm and you said that I would have to do a realignment to get things right. That meant more $$$$. I used to work on my own cars so I know enough of when someone is lying to me. read more

Quick and polite service. I recommend calling ahead so you can find out how long your wait might be. When we called he said come in 15 mins and we were the only ones there. Really reasonable prices and this will be my second time going. Recommend! read more

I just moved to the OC and was looking for a good legit mechanic. Alan is now my new mechanic. He's honest and straight to the point.

Support small businesses! read more

Brought my car in for an oil change, Allan is good at his job. It was done quickly and efficiently. I was charged half do what I usually pay at Jiffy lube and the only reason why I didn't go there is because of all the issues that are coming on the news about them. This place was great, it was at good prices and I will be a returning customer. read more

Kool Auto Service - Auto Repair Near Me - La Habra, California

My family has been going to Kool Auto for 4-5 years. He has never let us down. He's done oil service, smog testing, and other repairs. Twice we've been in with our cars needing what others have said would be expensive repairs. Both times I expected that the repairs would be in the hundreds. Both times they turned out to be less complicated repairs. He has had the opportunity to charge us for expensive repairs but didn't. He is by far the most honest mechanic I've ever dealt with. His prices are reasonable. He is reliable. He is straightforward. I wish that all service providers followed Alan's example. I hope he stays in business for many years. read more
