What does What Year Is offer today?
What Year Is publishes serial number decoders today. The home systems age report is a waitlist, and anyone on it gets one email on the day it opens. The decoder pages explain each manufacturer’s serial format, where to find the rating plate, and how to read the date, with worked examples.
Which brands does What Year Is cover?
Each published decoder covers one manufacturer, or a family of brands that share a serial format, across water heaters, furnaces, air conditioners, heat pumps and boilers. The brand list on the home page links every one. Brands whose formats we couldn’t confirm from the manufacturer’s own documents aren’t published yet.
Is What Year Is affiliated with any manufacturer?
No. What Year Is isn’t affiliated with or endorsed by any manufacturer, and it doesn’t give repair, replacement or safety advice. The manufacturer’s customer service line is the authority on any one unit, and a licensed technician is the right person to judge its condition.
How does What Year Is check its facts?
Every serial format comes from the manufacturer’s own website, service literature or support pages, and every page shows the date we checked it. The editorial standards page explains how pages are sourced, dated and corrected.
