Cannot say enough good things about Leo and all there. My 2020 KIA Optima experienced severe electrical damage from a rat infestation. Leo and company took that car and completely repaired it. Could not be happier. Leo communicated powerfully and clearly and respectfully in a very dependable way. A great pleasure dealing with him. read more

Super quick, fair price, great communication. I'd absolutely recommend and come back. My AC had been gradually getting worse for the last year or two, so I called in. Leo was quick to respond, explained everything they'd be doing, so I brought my car in for diagnostics. Quick call back, he explained what parts of the AC system needed repair and why, the cost breakdown with parts and labor, and answered questions I had about the other options for preemptive maintenance. They fixed the AC, it was an easy pick up and my AC works great again. read more

Excellent, honest service. Leo, the owner, and Michael, one of the technicians, were direct, no nonsense. The air conditioner in my 2007 Rav R was blowing warm air. I took it to a Toyota dealer who RECOMMEND REPLACING HIGH PRESSURE SIDE AC LINE at a cost of $1591.00. Looked on Yelp and found One Stop Auto Air Conditioning & Electrical in Pasadena with 4.6 Stars (156 reviews). I called and Leo thought they could do it for less and recommended I bring it in. I did. They confirmed the leak and repaired it in a couple of hours for a third of the Toyota estimate. Not only that, but because I was didn't have anyone who could come pick me up, Leo moved me ahead of other cars waiting, including a Bentley, and got the job done in a couple of hours. Leo asked me to bring the car in to him if I had any problems, and he'd take care of it. My air conditioning is blowing cold! Just in time for summer, which is going to be a hot one. Can't recommend them highly enough! read more

Leo and his team are true professionals. They are honest and do good work, very friendly, and helpful. Thank you read more

I had a great experience with One Stop Air Conditioning! They got me in right away, and Leo kept me updated throughout the entire process, explaining what was wrong with my car. The repair was completed quickly, and my car was ready the same day. Most importantly, my A/C is working perfectly again! I really appreciate the excellent service, communication, and quick turnaround. I highly recommend One Stop Air Conditioning to anyone who needs their A/C repaired! read more

Great technicians. These guys know what they are doing. I had a leaking ac and a general mechanic was not able to find it. Eli here found it very quick. He had good communication, let me know what it would cost and was flexible. Professional and efficient. Highly recommend read more

I brought my car in on a Friday afternoon for an A/C diagnostic. Within a few hours, I received a quote to repair the compressor at a very fair price. The mechanics got to work right away, and I was able to pick up my car by noon the next day. The repair was done professionally and with great attention to detail. The team went the extra mile by replacing the filter and a few other related components. Now the A/C works like it did when the car was brand new. The owner was very friendly throughout the process and kept me updated on the progress of the repairs. The entire experience was smooth, honest, trustworthy, and stress-free. I highly recommend this shop to anyone who needs A/C diagnostics or repairs. Excellent service, fair pricing, and quality workmanship! read more

Was supposed to arrive by 9:30am. Overslept due to moving the night before and phone died. Got there at 10:15 he still took me in. Informed me about the honda civic ac issue as the warranty is extended to 10 years but also let me know that not only the under warranty part front seal and compressor was leaking but my evaporator as well. Quoted me and let me know hed try to finish that day which was really nice. There is no lounge so just went to the nearby Vons Starbucks to do some work. Theres some coffee shops nearby too. Him and his guys worked on my car and got it all fixed and let me know exactly what to say to the honda servicemen. Do note that the evaporator core was not underwarranty and is the toughest job to replace as shown in the photo below. The front seal and condensor are the easier job which he let me know he made it easy for the honda service guys to see and diagnose. Thanks to him i wasnt charged for the diagnositic at the service center just like he said. All in all, my car was done from 10am to 4pm and my ac was blowing cold and he was 100 percent right on the honda service. Ac is blowing cold, only issue was that there is a alittle musty smell but will update if it lingers for more than 2 weeks. read more

A bit rude over the phone. I don't think a business should ever assume you don't know or understand how automotive parts work. Sounds a bit shady. I will take my business elsewhere. read more

Great service and very informative. Results are amazing and couldn't be more happy. Thank you!

Leo and his crew have helped me on numerous occasions and each time they have gone above and beyond the call of duty. When they could have charged me extra for a tough to get part they found a way to fix it and make it work. That's what makes a place like this exceptional. Thank you. read more

I would really recommend One Stop Auto Air Conditioning, really professional and knew exactly what was the problem! Leo and his team was quick and precise in the repair! Very reasonably priced and didn't take advantage of us not knowing anything about AC repair. I would definitely give them 5 out of 5 stars! read more

I took the 2021 Toyota Tacoma for electrical work, Leo and his team were very professional and took care of the wiring to fix the lights. I was happy with the service. I would recommend them for any electrical or A/C issues. Previously they fixed a broken window that would not roll up. Make sure to make an appointment as they are always busy. read more

Leo the owner was able to help me right away with a complicated replacement of my AC condenser for my hybrid vehicle. It's not an easy job and the dealer would charge big bucks . Back on the road with AC blowing cold. Recommend 100% :) read more

I brought two of my cars here and they'll always provided great service. This last time I visited they took me in last minute as a walk-in and did an ac service on my car. They're knowledgeable with older cars as well. read more

This place is amazing. Leo and staff is super friendly and was able to meet all my ac needs. He was able to also explain everything that was wrong with my compressor as well. Definitely highly recommend this place if you have AC issues with your car. read more

Leo was great. Had my car in there at 9 am and it was done by 3:30 pm with a new AC compressor. Not inexpensive but reasonable considering parts cost and labor. read more

Professional, explains their work clearly, does the job right, and stands by their work.

what can I say? there's a reason why they have so many good reviews. they do a great job, they don't take forever and they're nice people. highly recommend this place. they fixed an electrical issue with my back lights that were ALL not working, in one day, and they all work great now. read more

Literally right around the corner from me and Leo was very easy to work with. Found a compressor for me that's getting more and more difficult to find for my 1991 Alfa Romeo Spider. Converted the car from R12 to R134a and now I have nice cool air in my vintage car. Leo is no nonsense and turns around cars quickly. Bring on the summer heat! read more

They suggested a hard reset for my car issue and told me they wouldn't be able to help with that since they don't have the equipment. They suggested I go to a nearby repair shop that does, so just for being honest and helpful, I gotta recommend the place. read more

Leo at One Stop Auto AC & Electrical was friendly, reliable, and responsive! He came as a recommendation for my mechanic, Hrant at Hrant Auto Services. Leo's team are seasoned mechanics that did a great job with my 2013 Toyota Prius C. Thanks, Leo! The auto shop is set just off Foothill Blvd on Vista Ave, roughly a block west of Sierra Madre Blvd. There's a small, but relaxing waiting area. By why hang around when there's plenty to do a few blocks south along Colorad Blvd. If you've got choices, then choose One Stop Auto. read more

Came in 8 am, had a new compressor and working A/C by 3pm. Other shops refused my car because it was too old and a foreign brand. Couldn't be happier with experience. The parts and labor came with a one-year warranty. read more

I can't say enough good things about this shop! What should have been 3 to 4 day long job ended up being done in just a 1 day and a half--I was honestly shocked at how fast and efficient they were. Leo was amazing throughout the entire process, keeping me updated every step of the way. He didn't just tell me what needed to be fixed--he educated me on the process, making sure I understood everything. He even provides a PHOTO PROOF! That kind of transparency and communication is rare in auto repair shops! Beyond that, they are extremely fair and generous. I got estimates from other places, but this shop went above and beyond, proving that they truly care about their customers, not just making money. From the moment I met Leo, I could tell he was honest and cared more about his clients than making an extra buck. He always guarantees that his guests and clients feel safe and comfortable, which is something you don't always find at mechanic shops. You can tell these guys have a real passion for what they do. A lot of people don't realize how hard it is to be a mechanic--fixing complex problems while balancing a high volume of customers is no easy task. It can be a lot of pressure, but they handle it like pros. If you're looking for honest, skilled, and fast mechanics who actually care, this is the place to go. Highly recommend! read more

Took car there based in recommendation from our mechanic Hrant in Pasadena who I trust and use for my cars. Look him up if you need work done. Anyways, Leo took in my 1998 Toyota' 4Runner and diagnosed the AC. During the process, he sent me pictures of the mess. This truck served duty on three of my father's ranches and critters had made nests inside the system, which is common. I will post the pics to show what they had to do. The AC hasn't worked in years. You'll see why. The work wasn't cheap and there's good reason for that - it was a mess!!! A day and a fraction later, its blowing cold as ice and we are thrilled. I believe in supporting local business and hard work. Expensive yes, but well earned. They had to tear 1/3 of the car apart to do this job. I recommend them 100% read more

Let me take you back about a year and a half ago. I bring my 2018 Honda Civic in because it's blowing out warm air. I've brought my previous car in to Leo and they seemed professional and about as honest as you can expect from an auto shop. He told me that the Civics around my year have been having AC problems (wish I knew that before purchasing my car but oh well) so he would take a look at it to try to figure out the problem. They don't take too long, maybe 45 minutes to an hour and tell me that it's a condenser and compressor problem and to fix would be $1600. That's no small chunk of change but it was in the middle of summer and it just needed to be done so what was I going to do? They end up "fixing" it and my car is cool again. Not. Only a few months go by and what do you know, warm air again. I bring it in and explain to Leo the situation and he says he'll take a look at it. They said they would put in a special dye and put in some freon and to wait until it blows out warm air again. A few months later it blows out warm air and I bring it in and now they say it's an AC evaporator core leak. The quote: $1600! I'm not about to get it "fixed" again only to have some other part go wrong and pay more money. You would hope that one trip would be all it takes to get it fixed (with a new car you would hope no trips tbh) but this whole situation really bothered me and made it seem like they were just out to get money. I'm sure there's a little part of me that understands that they're just doing their job but I feel like they should've tried to look for all leaks the first time. Maybe I'm just the world's unluckiest car owner. But fool me once, shame on you. Fool me twice, shame on me. I ain't getting fooled twice, I'm just going to be AC-less thanks to One Stop. read more

Was recommended One Stop Auto by Hrant to fix windows that would not roll down. We spent $1500 the first time (May 2021) to replace all 4 window motors and to get a new car battery. A week or so later, the windows stopped working again. Life got in the way (covid, pregnancy) and we did not bring the car in again until November 2021. He "fixed" the window, then it stopped working again within days. Brought it back December 2021. "Fixed," stopped working within days. Finally brought it back in April 2022 (at the very end of the one-year warranty) and he finally fixed it for good (well, 3 of the 4 windows work consistently - 1 gets stuck. He only replaced the 1 window motor that consistently does not work). According to them, for the initial repair (in May '21) he was sent a faulty window by Subaru. At the end of the day, is it his fault that we was sent a malfunctioning window? No, of course not. But it IS HIS FAULT that it took FOUR TRIPS for him to finally realize the problem and fix it. (I should add that, when I visited in December '21 during the height of the omicron wave when there was an indoor mask mandate, he did not wear his mask inside his office) (I should also add that, when I called to schedule a time to bring my car back in the 2nd or 3rd time, he casually said "Bring it by tomorrow morning!" When I showed up, he said "We're busy today, come back tomorrow." UGH) Two stars only because he ultimately did fix the problem and the warranty made all of the additional trips free. Would not recommend or use again. read more

Awesome service, quality work! Came with a wiring problem in my car and got it back couple hours later.

After, 2 other shops, failed or ripped me off. One Stop Auto AC came through and fixed my AC. Highly recommended!

Leo and his team were total professionals. I had questions after my heater core was replaced on my 2001 Silverado. Leo is very responsive and understands the work he does very well. I recomend these guys any day. read more

The car's air conditioner was not cooling. I contacted 5 Auto repair shop. Mr Leo was very polite in answering all my questions and gave two alternate solutions to pick from to set the AC right with pros and cons. Very helpful. Now I can be comfortable in the scorching heat read more

One Stop Auto A/C really is one stop! I dropped my car off before the Christmas holiday (amazing) because my A/C stopped working. In less than a day, OSA found a crack in my radiator that was causing the A/C compressor to fail. After giving them my extended warranty companies phone number, they took care of the rest. It took a long time for me to get my car back but that was 100% my extended car warranty companies fault. They were probably spending more time calling people about their car's extended warranty than checking in on my claim (kidding but not really). Once my claim was approved, my car was fixed in 2 days. I would definitely recommend OSA to anyone who is having issues with their car's A/C or cooling system. read more

Hell the f**k no! Complete scammers!!! Was referred here by Hrant because my break lights weren't working after taking my car in to get the breaks changed. Guy at hrant tells me that my break lights weren't working which was a complete surprise to me. Being that I never actually see my break lights go on while I'm driving he has me stand behind my car while he hits the breaks and sue enough, nothing... So I go over to this place with a friend of mine following me in case I need to leave my car for a while. When I get there this guy takes a look and tells me I need to leave my car with him overnight. I'm honestly not getting a good vibe from him and I swear there was nothing wrong with my break lights before bringing my car to Hrants. So I tell him I'm good. I'm just going to bring my car to the dealership and have them fix it. Now at this point the guy suddenly gets confrontational with me. Telling me don't be ridiculous, dealer will charge me way more. Now I really don't like his attitude and I insist on him giving my keys back so I can just take it to a dealer. He goes and gets another guy and they speak in a different language for a minute. Then the guy I'm talking to gets down and does something around my break pedal then tells me ok it's fixed.... They really did not want me to take my car to the dealer. I'm sure they were afraid the dealer would tell me they were trying to rip me off. As soon as I insisted they give me my keys back he suddenly knew exactly what was wrong with my breaks and fixed it in less than 2 minutes. These mother f**kers are running a straight up scam! I'm super pissed at this point and go back to confront the guys at Hrant at which point the owner gives me a full refund for my breaks He swears the guy that worked on my car there was new and that his normal guy was away. I don't know if he was telling the truth or if this is some setup they have but my friend witnessed the whole thing. DO NOT TRUST THESE GUYS! read more

My alternator died on my way to work to a point where I lost power steering. Leo was quick to set up a call to discuss the problem and gave me a reasonable quote. I was able to drop off my car with Mike before noon and it was ready by 3:30p. They replaced my alternator, put air into my tires, and checked all systems were good. I definitely recommend this place if anything in your car needs to be fixed. Everyone was nice and service was quick. Thank you, Leo and Mike! read more

Called about an electric issue they said it was too long of work. No one seems to want to work anymore.

Clearly, I can appreciate how many of One Stop A/C customers have experienced excellent service. Bluntly, anyone who give this shop less than 5 stars is not willing fully understand the value of an expert shop. Not only have I had my car (Cayenne Turbo S) A/C serviced, but I had an issue with my RV - Moto Moto A/C performance. Leo's definitely knowledgable and was always available to answer my questions. Top-Tier service! Keep up the good work guys... read more

10/10!!! Brought my car in because my AC stopped working and left it for the day to be diagnosed. Got a call a few hours later from Leo, what a sweet man. He kindly explained to me what was wrong and why they needed to do A,B,C. He was very patient with all my questions and so helpful... just so damn nice! Which as a woman taking a car to an auto shop, is not always the case, unfortunately. I opted not to get the work done as it's a little out of my budget right now (and this is on me because I didn't really do my research on ac repairs) but I highly recommend this shop for the customer service and respect alone! Leo even waived my diagnostic fee, like the Angel he is, and told me to save it to put it towards the repair whether it was with him or someone else!!! There are still honest/good people in this world and Leo is one of them! read more

TLDR: great business, fast, quality work, good prices. A little over a year ago I realized I had a small leak in my ac system. So I went to autozone and bought up some triple AC sealer and put it in my car's AC system. I followed instructions but a few days later going to drive my car, my AC system wouldn't stay on. It kept clicking and turning off. So I searched and called around a few places and the owner here was really straight forward about the risk of the sealer products. I was planning a big camping trip and I needed my AC ASAP. So I took my car into the shop and dropped it off. They had to clean/flush out the whole system because the sealant acts like a heavy glue. They also needed to swap in a new condenser and compressor. They had my car back to me the end of the next business day. AC has worked great ever since. So very happy. So a little under the year mark I was noticing some dirt and oil build up at the condenser coil connector so I took it in. They fixed me up and changed the seal for me and I haven't had a problem since. I will 100% go back to this shop for any AC needs. Thanks again guys and great work. ** keep your receipts (or at least a photo) and don't be afraid to call back IF you do have any issues. 1 year warranty on the job in my case. Great guys and great service. read more

Leo took care of my new to me Miata immediately giving me cool air with a year guarantee. Great service, price and communication.

Leo was extremely helpful in getting my ac in my Honda back to blowing cool air. I was pleasantly surprised how efficient the whole process was. My air conditioning hasn't been working the last couple of months and being in Southern California that is extremely painful. I contacted Leo via yelp messaging on Thursday night...he responded right away and even told me I can drop off my car the next morning before they opened to accommodate my work schedule. I filled out the paperwork and left my keys with them. Throughout the day I got calls from Leo updating the status of car. When I left work Friday afternoon my car was ready and I was rest assured with a 1 year warranty. I highly recommend this place. read more
