I believe that Rheem and Ruud are basically the same like Trane and American Standard. Is this also true about Armstrong and Lennox???
With the exception of oil furnaces & residential packaged units which Armstrong makes and commercial stuff that Lennox makes, there are no similarities.
lennox is not the same as armstrong lennox owns armstrong company but they are all together different
it's like comparing mercedes(lennox) and chrysler (armstrong) same parents two different kids.
