Fix it, or replace it?

Computed from our published flat rates and a deliberately simple used-value estimate. Sometimes the answer is: don't pay us. That answer is the point.

How the math works: we compare our cheapest sensible flat-rate fix for the class against a crude used-value estimate (roughly 55% of new after year one, then about 15% more gone each year, floored at 10%). Real condition can swing the used value either way; if the numbers land close, the full guide walks the questions the calculator can't ask. If it says fix it, the diagnosis is free when you approve the repair.
