I’ve been using Celerity Systems at my office for years and have never been disappointed. Celerity Systems has always provided quality service at affordable prices. Response time is quick. If you’re ever having tech troubles I’d highly recommend using David with Celerity Systems.

David is extremely knowledgeable about computers. I had a problem with my laptop that was virus related. I called David and he was able to diagnose and fix my problem within 2 days. Over a weekend! He came to my office, ran some tests, determined he needed to take the computer to his office, and then dropped it off on Sunday afternoon just in time for my important meeting Monday morning. And it was super affordable. Who could ask for anything more? Highly recommended. Thank you, David!

David from Celerity Systems has helped us immensely in our business and at home. His knowledge of all things tech is extensive. He’s helped us set up our wireless network, clean up computers, purchase a new laptop, and is about to help us set up internet TV. I’m sure we have only scratched the surface of all his services he can provide, but we look forward to working with him in the future to help grow our business and help us become a high-tech home as well!

Thank you David/Celerity Systems for reformatting my laptop. That saved me several hundred dollars by not having to buy a new unit. The in office pick up and discussion time was invaluable. Good luck and keep up the good work.

When Celerity Systems sez you can relax, they’re not kidding. David keeps my Mac running in tip-top shape; he’s a wizard at diagnosing and fixing whatever the problem may be. I’d recommend him without hesitation.

Celerity Systems truly understands what it takes to keep my business running. Anytime I used to have a computer issue I would call the most obvious free technical support only to have them point the finger at someone else. After a few hours of this I would usually wind up with the original company. Not only is this stressful but it is also unproductive. Since using Celerity Systems my entire network seems to run smoother with less downtime. yesterday i have my computer had a no power on moneter but one call to celerity systens say just change power cable it will work .i took that adviser it was working instantly, thank youf the service.

David makes fixing computers easy. I used to build my own systems and troubleshoot my own computer issues but it would sometimes take hours to fix a few items. I realized that my time fixing a computer issue lost me money because I could have been doing more productive things with my time. He’s setup a network for me, maintained it, dealt with customer service with some 3^rd party software that I’ve installed, and just basically troubleshooted some common windows issues. He makes it easy and is very sensitive to the fact that if your computer system is down, you lose money so he’s always ready to help.

Let me start out by saying I feel I am somewhat knowledgeable about common computer functions and maintenance when the reality is I know just enough to get myself in trouble. So when I messed up my computer, I had a business card for Celerity Systems and I gave them a call. David came out and efficently and expertly got me up and running again! I would defintely use you again. Next time I will spend my time running my business, not fixing computers. Thank you and great job!
