I did not know it at the time but the pump had failed leading to my CPU (i9 12900k) redline for the subsequent 4 months - by the time it was May, my computer would regularly screen tear during VR, crash during games, and I was at my wit's end. I tried everything on my own until I followed up with Jose at APlus Tech Labs. He identified the issue, offered up upgrade my CPU and replace it with a new AIO Cooling system. I was very happy with the price and lead time. I wound up bringing Jose my 2nd PC as well! For this 2nd PC, the PSU or the Motherboard had gotten fried so we had both replaced in a matter of days. I really appreciate the communication and he was even able to meet me afterhours as I was unable to come during regular business hours while I had a deadline to meet to get this 2nd PC set up at home. Thank you, Jose. Appreciate what you do!~

Pricing was great as well.

I initially tried to show mike the problem but of course it wasnt happening during his testing. He said hed take a look and quoted me an estimate based on what he thought the problem was and said it would take a few days. The next day he calls me and tells me its ready for pick up and he fixed the problem. Charged me less than quoted and its been working fine since. No damage no extra upsells, just good honest work. Mike and his team are professionals and broke everything down so i understood what i was paying for and their work is super solid. Cant even tell my console was taken apart. Now its running smooth and i have a trusted place i can take my electronics. I highly recommend them and will continue to use their services.

Everything was handled quickly, and at no point did I feel like I was being upsold or taken advantage of. The pricing was extremely fair, especially considering the high quality of the work. The shop itself is clean, organized, friendly, and inviting, which immediately gives you confidence that your equipment is in good hands. Fast service, excellent workmanship, fair prices, and someone who clearly takes pride in what he does. Owner is A++++++++ -- fast, friendly, knowledgeable, and trustworthy. I wouldn't hesitate to bring another console here and would recommend this shop to anyone needing a repair. Easy 5 stars!

James was able to spot the problem and was willing to give it a go. Success! For a very reasonable price, my unit was back in operation. Despite replacing two additional capacitors, James stuck to the original quote. They could have just told me, no. I'm sorry, we don't attempt to repair things like this, but they gave me the time to take a look to see if they could help me out. Highly recommended. Thank you Fix Lab!!

I reached out to Sam, and he first tried to help me over the phone. When that did not solve the problem, I scheduled an in-home visit. He came by the very next day at a time that worked for me and spent about three hours working on my gaming laptop. He found that the hard drive had failed and replaced it with a new one. I felt the price was very fair, especially since there were no markups on the part. Sam was friendly, helpful, professional, and easy to communicate with throughout the whole process. I would definitely call him again for any future computer repair needs.

Once to Fry's and another time to another mom & pop repair. Both were over 10 years ago and both times I felt I was ripped off. After scanning througb the 1 & 2 star review's on yelp, I found this place. Jose wasn't available, but I was assured that they would find out what was the problem with my tower. Jose was nice enough to respect my lack of knowledge when it comes to PC's and I felt I got a steal. I will definately be back if I have another problem and or need to upgrade my PC.

Expert Reaction had 5-stars so I decided to give them a try. First of all, we're both in Covina and they offer free pick up and delivery. Marcus, the tech, explained that diagnostics are $99 which would be applied to any repairs. After he got started he sent me several texts to let me know what he was finding and what he would be doing. He determined that it was badly corrupted and he'd need to reformat the hard drive and reinstall Windows. (If you don't back up your files like I do everything could be gone forever.) He also checked for hardware problems even after determining that it was software just in case. End of the story is that I got a like-new PC for $170, when I feared that I was going to have to buy a new one. All companies should operate like this one does - and I would say that even if they hadn't been able to fix it.
