So........while I was picking up future compost materials from the windswept backyard, (gum leaves, bouganvilla blossoms, palm fronds, silky oak golden blossoms) ....... the mind wandered  to really interesting stuff like Freddie's vinyl situation.

So I played with the 'ATMOSPHERIC" theory.  

Here goes.  Don't shoot the mad thinker.

Imagine the air conditioning is operating on a really hot windy day and it's sucking .  

a) The westerlies are carrying coal dust from Gloucester; or

b) Freddie and Mr Tape-measureman are kicking up a dust storm outside with the planting project.

The airconditioner has collected dust in the filters.

Following the installation of her beautifully patterned flooring, there's another hot day.  

Freddie decides to cook, with the exhaust fan doing its job.  She's getting hotter.  The airconditioner is turned on.

Would the airconditioner be blowing fine dust from it's filters and it's being drawn into the kitchen by the exhaust fan?

That's it.  That's my atmospheric theory.
