An optional warranty arrangement should be evaluated by its actual coverage, conditions, and project requirements. A longer headline term does not automatically make it more useful for the owner's needs. Coverage and workmanship scope remain separate questions.
What to do next
Request the documents for each option and ask what changes in the installed system or inspection process. Compare exclusions and responsibilities. Avoid assigning a financial value to coverage without understanding what it provides and what the owner must do to maintain it.
