System Repair or Replace Calculator

Weigh cost, age, and condition to see whether repairing or replacing makes more sense for your home.

A transparent, multi-factor comparison

Compare your confirmed options.

Choose answers that reflect what you know. Unanswered or uncertain scoring information does not become an assumed answer. Safety guidance does not wait for financial details.
