COI Computers

COI Computers is a computer repair service in Glendale, AZ, that has been building and maintaining PCs since 1991. The company provides custom computer systems, PC maintenance, repair and support, networking solutions, PC parts and upgrades, and new media development for clients across Glendale, Sun City, Scottsdale, Phoenix, and Peoria. Their retail location is at 20325 North 51st Avenue, Suite 114 in Glendale, where they offer hands-on service to walk-in customers alongside their broader support work throughout the valley. COI holds a rating of 4.90.

The company's approach centers on individually configured systems rather than pre-built packages. They work with clients to identify what they plan to do with their computer both now and in the future, then guide component selection from a wide range of reliable parts to match the customer's needs and budget. Each system is assembled by hand by a skilled technician rather than produced on an assembly line, with every detail tuned for maximum power and ease of use. COI emphasizes educating their clients so that purchasing decisions are based on facts rather than mass marketing. Their support team operates on a personal basis, knowing clients by name.

The shop sits on North 51st Avenue near its intersection with West Beardsley Road and the Agua Fria Freeway, about 0.2 miles from each. Casa de Montanes, a local nature preserve, is roughly 0.7 miles away.

COI Computers has served Arizona residents and businesses for over 35 years and has been repeatedly named among the Top Ten Technology Providers in Arizona. Their longevity and consistent customer rating reflect the trust they have built through hands-on building, personalized support, and a consultative approach to every system they assemble. For anyone in the Phoenix metro area looking for a custom-built PC or reliable local computer repair, COI's decades of experience and commitment to hand-built quality make them a standout choice.
