About Us

Located in Cobourg, Ontario, Onsite Computer Services & Sales opened in October 2000. We repair between 40-70 PCs per week for home users, small business, and large networks. We have done work for over 6,500 clients in the Northumberland region!

At Onsite we have two full time technicians, 1 contract technician, and one part time technician allowing us to offer very fast response times.

We subscribe to an online service (Log Me In Rescue) that allows us highly encrypted access to client computers when issues can be resolved remotely. This service and access to the computer is initiated by the client, and is a strictly limited in time frame (i.e. when they close the support window, we lose access).


"Onsite Computer Services have provided extraordinary service to our family. They have kept our many computers up and running, provided prompt and expert repairs when needed, kept the prices low, and left us confident that our computers are in the best hands. I am deeply impressed by Onsite and strongly recommend it to anyone."
