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.

Not only did he reassure me that he'd take care of it, but he got my laptop back to me the same day.

Multiple staff members in my office have complained of his rudeness and recently his comments are dominated by his desire to avoid taking responsibility for anything.

Completely unprofessional.

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!~

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.
