What Our Clients Say
“Greatly recommend Sunil's services. Diagnosed and repaired my laptop over the weekend, I'm saying this as a UofC student, his service was quick and affordable. Provided detailed information regarding the progress on my laptop, sending messages, photos and videos. He was very accommodating. Even more so given he took my request during this heavy winter, and drove me back to campus so I didn't have to wait for the bus in the cold. Again, I highly recommend his shop for anyone looking for quality service. Edit: Nearly forgot, he also took the extra time to help me with the audio software issues I've been having. Despite it being a late request.”
“Sunil is a great guy! He fixed my iMac computer just for one day, it works really good!! Two thumbs up for this guy! I highly recommend him.”
“I recently visited SUN-SYS Computer & Printer Repair Services after having ongoing issues with my printer that made me consider throwing it away altogether. The gentleman who assisted me was extremely professional, honest, and upfront about the repair process. He clearly explained what could and couldn't be done, and I truly appreciated his transparency. He was able to fix my printer quickly and efficiently, saving me from having to buy a new one. His pricing was very reasonable and exactly as quoted—no hidden fees or unexpected costs. It's rare to find someone so genuine and reliable in their service. Excellent customer service, fair pricing, and trustworthy workmanship.”
“Sunil was very helpful in fixing my printer problems. He was reliable, quick, and very pleasant to work with. I really appreciated his follow up service and he has also been very helpful in sorting out a problem with my computer. He is very knowledgeable and so pleasant to deal with! I highly recommend Sunil and I know that he will be my "Go-To" assistant whenever I encounter future computer/printer issues! Many Thanks and Top Marks to a real professional....!!”
“I was so impressed with SUN-SYS! Sunil cleaned and serviced my printer to perfection, explained the work, showed me pictures he'd taken of the inside before it was cleaned, gave me good advice and now it is working perfectly! Not only that, but it was ready the next day and was super inexpensive. He wouldn't even let me tip him! I will be going back in future if I have any other computer or printer issues. Highly recommended!”
“I worked in IT and I know computers but I needed help with something delicate related to my laptop I was not able to fix on my own. Sunil is a high level professional and he found the reason of the problem, and provided the best solution. After he fixed everything he explained to me every step in detail. He is very honest and he didn't over charge me for "made up services" like many repair shops like to do. Cannot recommend this business enough.”
“I recently visited Sunsys for an issue with my laptop. I cannot recommend them highly enough as laptop was fixed and running flawlessly in a fast turnaround time. It's clear that Sunil takes pride in his work. Interestingly, while chatting with Sunil, I casually mentioned my watch had died. Without hesitation, and completely out of the scope of their service, Sunil offered to take a look and was kind enough to replace the watch battery for me right then and there. Overall, It wasn't just about fixing my computer; it was about providing an outstanding customer experience. They've earned a customer for life!”
“Super fast turnaround and very honest diagnosis. Sunil took care of my computer issues promptly without any hassle or inflated prices. Great communication and professional service throughout.”
