Founded in 1991 by Bill Marks, Computer Training & Support started as a small company to provide individuals one-on-one on-site computer tutoring/training. In 1993, our company was written up in the Pioneer Press pointing out our presence to new computer users. Since then, we have been recognized by various newspapers and media. At the beginning of 1995, when computers gained popularity, CT&SS started to offer classes in local Park District Facilities bringing instruction into the backyards of homes and small businesses. To this day, CT&SS continues to offer both one-on-one on-site hands-on tutoring plus affordable small group classes in Chicago land Park District facilities ranging from $25 - $175. Our classes are offered primarily to the beginner but also to the intermediate and advanced computer user. Everything we offer provides repetition and challenge to enlighten computing in the present era.

I have spent 30+ years in a combined Professional and Home Audio arena. This led me down the path of acquiring a profession into the Healthcare IT/Bio-Medical Engineering environment. While working in these spaces I have maintained a large network of customers supporting their home audio/visual and home networking needs.

Do you want help setting up, fixing, or maintaining your technology? Do you want simple and reliable technology solutions that just work? Do you want a technology partner you can trust to understand your needs? Then contact me, Joe, your Duck IT personal technology partner. My goal is to keep it simple and make it right the first time! I want to make your experiences with technology easier, by making technology work for you (not the other way around). I respect your time and want to make sure you have more of it, to focus on what matters to you. I believe that technology can make our lives better, if we first make technology more accessible and integrated for all! At Duck IT we “quacked” the code on personal technology. Don’t waste any more of your time struggling with technology or faceless pretend partners. Just say “Duck IT” and schedule a convenient time that works best for you. The only regret you will have is not saying “Duck IT” sooner.

Computer Repair questions, answered by experts

Costs depend on issue severity, parts needed, and labor rates.

Yes, an arc fault is serious. Caused by damaged or overheated wiring, an arc fault can trigger a spark that can cause a fire. And because these fires often start behind walls, they have the potential to spread before they’re detected by smoke alarms. According to the Consumer Product Safety Commission, an estimated 50% of electrical fires can be prevented by using AFCIs.

Many providers offer repairs as an additional service. Confirm with your contractor.

Aim for a uniform, smooth joint to ensure a good electrical connection. If it looks crusty and uneven, your iron tip might be dirty or the joint isn’t hot enough. To keep the iron tip clean, wipe the tip with a damp sponge or brass tip cleaner when you spot black spots or rust to remove any oxidation and flux residue. Tinning the tip surface with a small amount of solder offers a layer of additional protection.

Yes, many repair services include upgrading outdated systems with modern features.
