Water Softener Installation in Vernon Hills, IL
Vernon Hills is supplied by Vernon Hills - Lake Co PW, 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
The supplier for Vernon Hills is Vernon Hills - Lake Co PW, drawing surface water. Surface water has had far less contact with rock, so it is more often soft enough to leave alone. Whether a softener is worth installing turns on the hardness figure that supplier publishes each year, not on anything assessed over the telephone.

What to do with thatGet your hardness figure
The annual water quality report from Vernon Hills - Lake Co PW carries the hardness figure. Get it first, because everything downstream depends on it. It arrives as mg/L. Equipment is rated in grains per gallon, roughly a seventeenth of the number.
With the figure in hand, sizing is one multiplication — water per person, times hardness, times people. If your fixtures also stain orange, iron has to be settled first — oxidized iron clogs softener resin.
