Source standards
Claims are drawn from primary manufacturer submittals and manuals, AHRI, ENERGY STAR, utility and rebate program pages, permit records, and provider-owned sources before publication.
No invented values
Product specs, prices, installer credentials, availability, ratings, and service claims are left unknown until a source confirms them. Retailer- and media-sourced figures are labeled as such.
Directory firewall
Payment for a directory listing never changes a profile's verification status, its ordering, or the evidence boundary applied to every provider.
