Standards

Editorial policy

Useful guidance depends on showing the assumptions, separating commercial relationships from recommendations, and correcting mistakes.

Independence

Calculator outcomes are generated from the inputs and published decision model. Advertisers and referral partners do not receive higher repair or replacement scores and cannot purchase a recommendation.

Sourcing and review

We prefer government, manufacturer, utility, and established technical sources for safety, efficiency, recalls, and product operation. Cost ranges are treated as estimates and are clearly distinguished from quotes.

Corrections

Clear factual errors are corrected as soon as they are confirmed. Suggestions should identify the page, the disputed statement, and a reliable supporting source.
