Andrei fixed my PC fast and professionally. The computer powered on but showed a black screen and I couldn’t access the BIOS. He diagnosed the issue quickly and got everything working again and fixed it within 4 hours. Clear communication, fair pricing, and reliable service I recommend him.
Andrei was a very knowledgeable and polite technician, and his services were reasonably priced. He repaired my desktop PC promptly and also thoroughly cleaned it. The service was highly professional and reliable. I highly recommend him and will be utilizing his services again soon. Thank you.
I spilled liquid on my laptop. After filling a form at onmain systems' website, they directly sent me a message for the solution less than an hour. They did a deep cleaned in a very short time. Even after finished it, they still checked on its condition. They offer quick and friendly service!
I am so pleased with the service. Of all the companies I contacted, Onmain Systems was the only one willing to repair my non-UK laptop; it needed a new battery. In a matter of 3 days (3 days for the new batery to arrive and only 30 minutes for Andrei to switch it) I had an efficient battery up and running. I was delighted that there was a pick up and drop off option, too. The price is reasonable, and so worth it for the work done. I highly recommend!
Andrei is an amazing and professional technician, and would wholeheartedly recommend him! My laptop needed a USB-C port swapped out, and Andrei was more than happy to help. He popped in to pick up the laptop and managed to get it up and running within the next day. Laptop working perfectly ever since. If you need a dedicated technician who can get your tech working again quickly, Andrei is the one to go for!
Stuck in London with major software issues, Andrei collected my laptop promptly from my hotel and 2 hours later delivered it back to me in prime working condition. His service, attitude and pleasant demeanor was a breath of fresh air. I can recommend him to anyone with tech problems.

Had a software issue with my PC after returning back after 2 months of not using it, was in luck that Onmain Systems was nearby. I was able to book an appointment the next day, problem was resolved very quickly and at a fair price. Service was impeccable, explained to me the possible issues and diagnosis. Had a lovely chat after the service. 10/10
