Water Softener Installation in Arlington Heights, IL
Arlington Heights is supplied by Arlington Heights, which draws surface water. That one fact does more to predict whether a softener is worth it here than anything a salesperson will ask you on the phone.
The short version
Arlington Heights supplies Arlington Heights from a surface source. Surface water has had far less contact with rock, so it is more often soft enough to leave alone. Hardness is published annually by the supplier, and that one figure is what a softener decision should rest on.

Where the water comes fromSurface water in Arlington Heights
This is a surface water supply, which matters for hardness: the water has not spent years in an aquifer dissolving calcium out of stone. Expect a lower figure than a neighboring town on wells.
Arlington Heights serves 20,539 service connections. That is drawn from the EPA's Safe Drinking Water Act file, 2026 Q2 refresh.

What to do with thatGet your hardness figure
Ask Arlington Heights for its water quality report, or find it online — hardness is on it, and it is the number the rest of this turns on. Expect it in milligrams per liter; equipment is sized in grains per gallon. The conversion is roughly 17 to one.
Put it through the sizing calculation and you will know what to accept and what to refuse. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
