If you’re budgeting a water softener installation in San Francisco, most projects run $1,021-$4,084, 28% above the $1,500 national average.

Easiest place to save: Test your water hardness before buying a system - either with a $10 test kit from a hardware store or a free test from your water utility. This determines the size you actually need.
