4 Big Reasons to Choose Central Office Systems to Support Your Computer Network


We Respond Within 5 Minutes Or Less. The average amount of time it takes for one of our clients to get on the phone with a technician who can start working on resolving their problem is 3.5 minutes. We know you're busy and have made a sincere commitment to making sure your computer problems get fixed FAST. And since most repairs can be done remotely using our secure management tools, you don't have to wait around for a technician to show up.


100% No-Small-Print Satisfaction Guarantee. Quite simply, if you are not happy with our work, we'll do whatever it takes to make it right to YOUR standards without charging you for it. And if we can't make it right, the service is free.


No Geek-Speak. You deserve to get answers to your questions in PLAIN ENGLISH, not in confusing technical terms. Our technicians will also not talk down to you or make you feel stupid because you don't understand how all this "technology" works. That's our job!


Peace Of Mind. Because we monitor all of our clients' networks 24/7/365, you never have to worry that a virus has spread, a hacker has broken in or a backup has failed to perform. We watch over your entire network, taking the management and hassle of maintaining it off your hands. This frees you to focus on your customers and running your business, not on your IT systems, security and backups.

Fast, Smart & Friendly! 

Central Office Systems makes us more productive. When we call, things get fixed in a quick manner.

They Listen and They FIX 

Help is a phone call (or email or chat) away  Knowing that COS is tracking the health of each device is comforting. We are able to plan ahead and prepare for replacements and/or updates.

Having worked in the corporate world and called a "Help Desk" a time or twenty, the first thing they always tell you to do is reboot the computer; as if I hadn't already tried that!  I have NEVER been asked/told to do that by COS.

They remote in and look at my problem and LISTEN to me.  On the very rare occasion that the help desk person cannot solve the problem, they will escalate to a higher level and my issue gets resolved, no matter how high up it might need to go.

Fast Response In Plain English

Our old IT company took days to respond. Central Office Systems is available right away.

They talk to us and let us know what they are doing and why in plain english, not whatever language computer guys speak.
