Chicago Metro Service Areas
Where QOS MSP delivers managed IT in Illinois
We've got you covered all over the Chicago area
QOS MSP provides managed IT services across eight counties in the Chicago metro — Cook, DuPage, Lake, Kane, McHenry, Will, Kendall, and Grundy — from downtown Chicago and the North Shore out to Naperville, Aurora, Joliet, Waukegan, and Crystal Lake. Outside those counties? Remote-first support reaches farther — ask.
Most of what we do reaches you remotely, so day-to-day support does not depend on where your office sits. When a problem needs hands on hardware, a technician is dispatched to your site anywhere across the metro. The map above shows the eight counties; the section below covers how service works inside them and at the edges.

How coverage works
Coverage has two layers. Remote-first support reaches everywhere — monitoring, help desk, patching, security, and most fixes happen without anyone leaving our side, so your location rarely matters. When a job needs someone physically on-site, an on-site technician is dispatched across the eight counties as the work requires.
“Outside the map” is not “no.” For a business past the eight-county line, remote-first coverage still applies in full, and on-site visits are handled case-by-case — tell us where you are and we will tell you exactly what service there looks like. Our managed IT services and pricing are the same wherever remote support reaches; only on-site logistics change at the edges.

Service Area Questions
-
Do you support businesses outside these 8 counties?
Yes. Remote-first support — monitoring, help desk, patching, and security — reaches businesses anywhere, so most day-to-day IT does not depend on your location. On-site visits outside the eight counties are handled case-by-case; tell us where you are and we'll confirm what's available.
-
Do you charge travel or trip fees?
No. There is no travel or trip fee anywhere in the eight counties — on-site visits are included in your managed IT plan. Note that plan covers our labor and management; hardware and third-party software licensing are billed separately.
-
How fast can a technician reach the outer counties on-site?
On-site technicians are dispatched as needed, and most issues resolve remotely first, so on-site timing is case-by-case rather than a fixed window. For the outer counties — Grundy and Kendall — remote-first support is the default, with an on-site visit scheduled when a problem genuinely needs hands on hardware.
-
Can you cover a business with sites in multiple counties?
Yes. A business with locations across several of the eight counties runs on one managed IT plan and one team — not a separate arrangement per site. Remote support covers every location, and on-site technicians are dispatched to whichever site needs them.
-
Can you support remote employees who live outside your service area?
Yes. Remote-first coverage isn't bound by the map — a remote employee gets the same help desk, monitoring, and security wherever they work. Our user fee follows the person, not the address, so distributed teams are covered without a location surcharge.
