- Test your water first — you may only need a filter, not a softener.
- Choose a metered unit; it uses 30–50% less salt than a timer model.
- Collect three written bids on an identical scope — spreads of 20–40% are normal.
- Book in the off-season and stay flexible on the start date to save 5–15%.
- Bundle nearby work into one mobilization so you only pay setup and travel once.
- Ask what the contractor would change to cut 10% without hurting durability.
