The decision this library answers
Which option remains defensible after cost, scope, risk, and uncertainty are made comparable?
Use the repair-or-replace guide after you have a written diagnosis. Use the quote-comparison worksheet when two proposals appear similar but include different work. For an efficiency upgrade, calculate the installed premium and a range of annual savings instead of accepting a universal payback claim.

Use this order
- Get the diagnosis, observed test result, failed part, warranty status, and repair guarantee in writing.
- Compare cash cost, financed total, remaining risks, corrected defects, serviceability, and expected ownership period.
- Define the evidence that would change the decision before choosing a contractor or equipment tier.
Boundary
A decision framework cannot predict remaining equipment life or override a safety finding. Major diagnoses deserve qualified verification when time and safety allow.
