Thank you so much for your help! Being without an AC in the middle of summer is not fun! I called so many places before someone referred me to this location and was able to get the problem fixed by the end of the day! Thank you LEO for having such an efficient team. :-) read more

I have an old 1988 Mercedes 560SL and wasn't sure any mechanic would want to take it in to diagnose my broken A/C. Leo and his team were able to diagnose the simple problem of a bad A/C pressure switch caused by the Aux fan not operating properly. They swapped the switch and got me back to my car in under 2 hours. Great service and communication and I'll be glad to be back again for any A/C issues. read more

They are quick to diagnose and give an estimate. Work is done with quality work and no issues. Hopefully, I don't need to return bit definitely want to recommend this shop for others read more

During the recent heatwave, I noticed my AC wasn't working. I tried to book appointments at other places, but they didn't carry the type of frion needed for my 2018 civic hatch. After I quick google search, I found One Stop, gave the shop a call, and was told they could squeeze me in. Upon arriving at the shop, Leo told me about how common it is for 10th gen civics to have AC problems and that they do 10-15/week. He texted me photos and updated me on the progress of my car and I was able to pick it up earlier than expected. Upon picking my car up, I cranked up the AC and it was good as new. I appreciated the service that was provided, fair pricing, up front, and no BS. I would recommended this shop to anyone having problems with their AC, especially 10th gen civic read more

I 100% reccomend One Stop A/C Repair! I arrived early without an appointment, Leo was able to squeeze my car in...diagnosed and replaced parts, serviced my a/c all within 1 day! I had my car back same day, I appreciate their professionalism and services! read more

My Air Conditioning was not blowing cold air any longer. I searched Yelp and found One Stop Auto Air Conditioning and decided to take it to them based on the good reviews. Leo and his team had it fixed in one day. Leo knows his business and is very knowledgeable. I've worked many years in the auto service industry and it's always a pleasure to find someone like Leo. Price was fair and the work was stellar. I highly recommend read more

Sent here as recommended by Hrant. Had my Prius V towed to this place to get it checked. Received a call later from Leo quoting me $4800 to change the hybrid batteries and replace the fuel pump. $4800???!!! Least to say I had the car towed back home. Paid the $100 "diagnostic fee" which I feel is another rip off. Glad to get my car out of that shop. Addendum: had my car fixed at another local repair shop. Ended up paying way less than what this place was quoting me for. They charged me for diagnostic fees that probably was never done. Probably just gave me a guesstimate. No error codes provided. Their mechanical guesses were way off than what the true problem was. read more

Amazing business with very knowledgeable owner and staff. Took me in on such short notice and fixed my AC super fast. I would recommend this shop to all my friends and family! read more

And on top of that he backs his warranty 100% I had a car that I hadn't driven in a while and I was trying to get the air conditioning at work and it wouldn't work so I had to take it back to him it's because I didn't know what I was doing but it still work perfectly it was just me but he check the car out at no charge and went through everything so what else can you ask for a reasonable price and they're kind he's the best read more

Great company, the owner is very honest and I will always take my vehicle to one stop for air conditioning service.

My Air Conditioner in my Work truck was not Working and it gets very Hot and uncomfortable without AC I needed it fixed right away! I went into one-stop auto airconditioning and electrical Leo the Owner diagnosed the problem quickly gave me a reasonable cost without trying to gouge me or charge me a diagnostic or estimate fee. I'm very pleased with the service I will be all my work trucks to him from now on. read more

All the dashboard and GPS screen lights went out one day. I took my car to Hrants who directed me here. They said the wires needed to be fixed and it would be a couple thousand dollars. They drove me to a car rental place so I would have a car to go to work. They called me to say that in fixing the car, the odometer now indicated lower mileage. After I paid and picked up the car, I noticed that in fact, they had replaced the odometer with another (used) one. It had a different frame from mine. Anyway some of the indicator lights weren't working so I brought back the car the same day. They said, oh, we were able to fix your odometer and I found that my original one was put back. Leo and his assistant were very kind and professional in attitude. . read more

Leo is amazing, was able to fix my car's issue, very responsive and even helped me with advice so that I wasn't hustled by another mechanic shop. A very caring and stand up man! Thank you Leo read more

Michael and Leo are a great team who rally care about their customers. I spoke more with Michael, who came up to my car as I pulled into the lot. I explained to him that the AC in my '09 Honda Civic was going on and off for about a year before it stopped working (only hot air was blowing). There is a $100 charge to figure out what's wrong with your AC, but it's waived if you end up fixing it with them. I was recently laid off from my job and Mike and Leo worked together to work with my budget. They were able to replace the AC clutch instead of replacing the entire compressor. For more complicated AC repair jobs, definitely give One Stop a try! read more

My mechanic, Hrant, sent me to One Stop for a mechanical issue with my VW. This is a family owned & operated shop, which I like. I did not have an appointment, but Mike was kind enough to let me leave my car for analysis. I got a call from Leo letting me know the issues with my car and we proceeded with the repairs. The folks here are great, were able to fix the problems, and the price was reasonable. read more

This review is long overdue but their good service compelled me to write this review. I had a an older Volvo whose air conditioning was no longer working. After a while, I frankly got used to it but their are some of those days when we all just die in the S. Cal heat. Anyway, after calling around, I took it in to One Stop, the owner checked out the car, suggested that a part could be repaired and gave me a quote of about $1000 versus the $1500 (approximately) for a replacement of the failing part. He attempted the repair, but the part was no good so, on his own, got the replacement new part. When I came to get the car, he told me what happened and I expected to be asked to pay for the new part and he honored his original quote. SUCH A RARE AND COMMENDABLE amount of integrity and honor AND, now 4 years later as the heat is picking up again, my A/C runs strong and cold! These guys are GREAT! read more

My husband was hoping that the first two shops were wrong about needing a new compressor for our Scion. No such luck, but the price for the repair was lower than the ones previously quoted. We were happy to have them do the job. They have a large stock of parts on hand and they pass the savings on to their customers. The team at One Stop inspires confidence. Their shop is clean and well-organized. We were very happy with the repairs. We especially liked talking to Mike, he made us feel like we were new friends, not just customers. I understand they get really busy in the summer. If you have an air conditioning problem, don't put it off. Highly recommended. read more

Poor customer service, unfriendly and rushed. I'd find another shop that isn't so stressed.

The gentlemen at this auto electric/air-conditioning repair shop are at the top of their profession. I received exemplary care and was impressed with the results. I strongly recommend them for any auto electric and Air conditioning concerns. read more

So glad I found Leo and his team. They were very straight forward and informative. Leo was willing to take the time to explain and show everything involved so I could make an educated decision. They were also not pushy or rushed like many auto shops. They truly care about their customers and stand behind their work with a 1 year warranty which provides allot of confidence. I would fully recommend anyone to work with them! read more

Excellent service and great price. They overhauled my AC. The work came with a 1 year warranty. read more

Edit: Owner just called me threatening to press charges for writing this review and told me that writing it was threatening him, so I changed "fight them" to "argue with them" to more accurately convey my meaning in case it was unclear. Misdiagnosed my problem, did $2,000 of work my car didn't need, didn't do work they claimed to have done. My 06 Pathfinder wouldn't start and I suspected an electrical malfunction so I took it here. They diagnosed the problem and did ~$2,000 of work. The car drove away, but 1 day later wouldn't start again. This time I took it to another mechanic who diagnosed a transmission issue and told me the diagnosis at One Stop was ridiculous (it was a single fuse [#10] at most, but probably 100% a transmission issue). The car has now been working for 2 months after the second mechanic. I later lost my keys while hiking and had my wife bring all 3 spares; none of them would start the car even though One Stop told me they reprogrammed them all (which they billed me for) after replacing my electrical system. I called them about this today to see if they would reprogram the spare keys and first they didn't remember the work from 2 months ago, then they tried to pass the buck saying they don't program keys they contract that out, then they said I would need my invoice showing exactly how many keys were reprogrammed (the invoice just says "keys" not a specific number, although I explicitly remember them claiming to reprogram 3 sets total because I couldn't find the 4th set until their work was complete and the owner's response was "3 is enough how many sets of keys do you need?"). Worth noting I have been extremely nice with these people in person, nothing rude, no complaining, just happy to pay for their time and move on to be done with them - they have been given no reason to be hostile or dismissive, and yet they won't do the work they were already paid to do after it became apparent they never did it. I decided to review them instead of argue with them because it's the best outcome I could hope for at this point: it's $10/key to get them reprogrammed at a locksmith so I'll gladly pay $30 to be done with this place forever, the parts were only half the cost of the original work and there's nothing wrong with the parts they installed, my car simply didn't need them or the $2,000 bill that came with them, and I don't want their mechanics working for free, so I don't want my money back; the best outcome for me is to share my experience and hope that I can save someone else from stepping into this catastrophe. read more

My key was stuck in my ignition and it wasn't coming out. I went to a lock and key place on Washington and they were able to remove my key but explained the wiring in my shifter most likely needed to be replaced as well as a part in my ignition and that a mechanic needed to fix it. They referred me to Hrant Auto Services and Hrant referred me to One Stop. When I arrived I explained to the worker (don't remember his name -- it wasn't Leo) about what was going on with my car. He looked at it for a few minutes and explained I had two options, 1.) leave it all day for a diagnostic check for $100 in order to see what would need to be fixed or 2.) have whatever needed to be fixed replaced and they would waive the diagnostic fee. I asked for a ball park price on what it would be costing me "$300, $500, $1000, $1500?". He said he had no idea and then threw out a few guesses on what the problem could be and what I would most likely need fixed. I said I would do just do the diagnostic test for $100 to see what was wrong and how much it would ACTUALLY cost. Once I said I would rather do the diagnostic he completely flipped and got really pushy explaining I needed to have all this stuff fixed and how much time and labor it would take them to do the diagnostic. I explained I'm not just going to agree to have my car fixed when I don't know how much anything would be costing. He then said they were actually (all of a sudden) really busy today and I would just need to call tomorrow. LOL. Anyways, another story about a mechanic trying to take advantage of someone who they think doesn't know any better. I ended up taking my car to Spence and Frye down the street. I arrived and explained my situation, they said no problem and took my car right away. They told me how much the new part would cost me and that they would call if anything else needed to be done/replaced as well as give me an updated price. Ultimately, I ended up needing a new shifter as well. They fixed my car for a reasonable and honest price and I didn't feel like I was being finagled the entire time. read more

My ten year old minivan's AC died. :( My mechanic told me the refrigerant level was good and that it was probably the compressor (also told me it would be north of $1700). My mechanic, like most mechanics and many dealers, doesn't mess with big AC jobs. So I went to yelp for help. Luckily, there is a guy in Pasadena who does only AC. Turns out is was the compressor. Leo keeps his shop well stocked. He also does the job right -- original Honda parts, also changes out the condenser, chemically flushes the system, new seals. $1400! Hundreds less than what my mechanic said it would be. It sucks to have an expensive repair but it was cheaper than what it could be and, most important, it was done right. Also... The cleanest garage I've ever seen. read more

I have brought a Subaru Outback to Leo for concerns over my AC system being weak. I found it have been fair to pay for his service to diagnose if anything was wrong with it. However he did not find anything wrong and he did not accept a payment. Instead, he demonstrated a lot of concern that there still might be something wrong with its AC and that I should bring it back to him immediately it stops blowing cold. Leo's character and care is what will bring me back to this shop if anything goes wrong with any of my cars in the future. read more

Wonderful service! Leo is honest and professional. He quoted us at a price and stayed true to it. It was a bit expensive, but considering the problem was a little motor deep inside Prius dashboard, we saved a ton of money. He had no air coming out of the main vents in the car, resulting in our daughter overheating in the back as the cool air could not reach to the back. They had to take it all apart and back together again. The dealership quoted us triple the price. And they would have probably just sent the job to him anyway as he is able to solve problems dealership can't even do. Highly recommended! Thanks Leo! read more

Hands down the best car AC repair in Pasadena. Great prices, super professional, very honest. I highly recommend.

These guys have fixed the air conditioning and heating system on my 2012 CRV. Both systems continue to work well after a few years. The service is friendly, prices reasonable, and the problems fixed. You can't ask any more than that. Great place! read more

Best service in town! Would give them a 10 star if I could. Best costumer service. Decent price, got the job done within hours.

We can finally take our car for family rides! Thank you and will refer anyone in need to the specialists!! You guys are awesome and have given us more than you know. read more

One Stop Auto Air Conditioning & Electrical - Auto Repair Near Me - Pasadena, California

After my car AC was broken down for months, I decided it was time to fix it before the brutal heat wave started. Going to One Stop Auto was the best decision I made. Leo was very prompt to reply to my messages and even made arrangements for me to drop off my car before the shop opened due to my conflicting work schedule. He even offered to drive me to work (1 mile away) after dropping off my car. I got called about 2 hours later after diagnostics were run, and was given a reasonable price for the fix. Picked up my car after work and the AC ran like new. It's been a few months and the AC still works great, no complaints at all. I recommend their services to anyone needing to fix their AC. Very professional, flexible, and affordable. Thank you, Leo and team at One Stop! read more

I had my AC fixed here and would highly recommend. Leo made sure I was happy with the fixes and adjustments made. Thanks again!

Wow!!! The owner and his dad were so honest and friendly. They quoted me a price, I declined. They tried a cheaper method for me and it didn't work. No charge! Rare display of honesty. read more

I highly recommend this company. The employees were awesome. I entered the business and explained the ac did not work and I also had a electrical problem. I was reasonably quoted for the ac repair. I left my vehicle there for the ac repair. When I returned the ac was repaired and the electrical problem was fixed at no charge. The ac is blowing cold and we could not be happier. What a great company. read more

I can't say enough good things about this place. We came in from out of town, our A/C went out on the way. I called and was told to come in right away. They got us fixed up and on our way back to Texas the same day. They even gave us a great lunch recommendation!! read more

I walked into One Stop Auto based on a referral from Hrant in Pasadena. I was having issues with my A/c in my car and thought it might need some recharge/freon. I go to pick up my car and they assessed my a/c in my car, should be 500 for a temporary fix of my expansion valve and 800 for a permanent fix. That was more than I wanted to spend and I didn't like how pushy they were and how they treated me. So I took my car to another mechanic for a second opinion. Turns out my expansion valve was not broken and all I needed was freon. Total cost $40 for a freon recharge. I saved over $450 by taking my car elsewhere. Bottom line One Stop Auto in my experience is going to try to swindle you. If they tried it once to me, they might do it to you. Do yourself a favor and take your business elsewhere. read more

After calling around town to get a price on repairing the starter on my 1992 lexus sc400, these gentleman bid the job lower than anyone else in town, and had the car finished the next day. Excellent, professional and enthusiastic is how I would describe them, They have the cleanest garage I have ever seen, and clearly take pride in their work. Ask for Leo read more

I would hands down 100% recommend this place to anyone. I had gone to 4 different mechanics over the course of the last year to get my AC fixed in my car and everyone kept saying it was the same issue and would presumably "fix" it just for my AC to go out again in the next week. Finally, I came to One Stop and they gave me a quote and had me initial by it so that there would be no hidden price changes. They did exactly what they said they would do. It was an extensive job but they did it and now for the first time in over a year I have AC! They are thorough, upfront, and honest. AND everything they repaired comes with a one year warranty. So that gives me so much peace of mind. Highly recommend this place! read more

Thanks Leo for honest service in the first place. He also can recommend the good mechanics if for some reason he can't do it by him self. read more

I had a short with my "driver-side" rear tail light. I had Firestone first look at it but they really couldn't do anything about it. I brought it over to One Stop and they were able to diagnose correctly the problem and give me an alternative than buying a factory wire harness. The harness would have cost 600.00. They got it done for a fraction of that price! Thank you again. I will come back and recommend my friends. read more
