- Its stated method checks decoding rules against known serials from recall notices, printed labels, and manufacturers.
Field notes
For decoding, the page says manufacturers encode production dates differently, often by year and month or by week. Its price estimates combine online equipment list prices with installation-cost data and adjust the labor share using local plumber and HVAC technician wages. The homepage also discloses that some phone numbers or partner links generate revenue and says those are labeled.
