I Have an Older Model Furnace, Where Do I Find a Current Model Number?
General FAQ
Answer
Review the "Obsolete Models" link on the Williams website, which cross-references older model numbers to their newer equivalents.
Other Brand Names
Williams manufactured furnaces for several other brands including:
- Dayton
- Dearborn
- Kenmore
- Montgomery Wards
- Sears

If your unit bears one of these brand names, it may actually be a Williams furnace, and this resource can help identify the current corresponding model.
