What Clients Are Saying About Us

We care about what our clients have to say, and so do you. Here’s what a few of them have told us about their experiences:

Our on-the-spot, go-to IT ‘Team.’

Absolute Computer Systems has been our hardware ‘go-to’ team for almost ten years. Tom, the owner, is extremely ‘hands-on.’ His staff is helpful and attentive to any problem that arises. Computer issues, as we all know, crop up at the least convenient time, and the ACS team is here for us every time!

ACS keeps our computer system running smoothly and minimizes any downtime that occurs. They were there to get us up and running when a ComEd transformer blew and left us without power for several days. They coordinate with our software company to maintain hardware integrity and make sure it integrates properly with the software. They monitor, repair and maintain the very costly equipment that is the lifeblood of our business.

By allowing ACS to take care of our computer needs, we can keep our focus on building our own business where it should be.

I truly appreciated the peace of mind.

I have used ACS for years. I have had them for all of my business computer and networking needs. We had a dual hard drive failure about two years ago, and our backups were corrupted. Tom and his team were able to save and restore our primary customer and financial databases, saving us thousands of dollars and possibly our business...

They have always been there for whatever the need has been. They are my first call if I am ever in need of anything they might carry or service. I can’t thank them enough for the peace of mind they give my wife and me for everything they do for us and our business. They keep us up-to-date and moving forward. I would highly recommend them to anyone looking for exceptional service. Thank you, Tom and ACS!

Immediate professional support

I worked with Tom and Absolute Computer Systems for five years at the Racine Community Foundation; however the Absolute Computer Systems is servicing all computer needs at the Racine Community Foundation for many years. Tom is very knowledge, honest, professional and reliable, he responds to client needs

within 0-30 minutes and sends the ACS’ staff immediately to resolve the problem. His services are high quality. He treats his clients with high respect and always is able to find resolution. Client satisfaction is number one priority for the Absolute Computer Systems. I would recommend the Absolute Computer Systems to all who needs fast and high quality computer service.
