I was reading around on ebay to day and saw 'Auto Clean'..
What the heck is that?
Gree 1 Ton 22 SEER EVO Ductless Mini Split Heat Pump 208 230 V | eBay
I've been thinking about a Reverse air flow in the outdoor unit,
to clean out the veg-matter that gets sucked in during the summer.
Backwards are might also be a neat function to clear out snow buildup too.
If used at the end of a defrost cycle..
I'm also wondering about the 'Dry Anti-mildew design'.
I can see mildew is starting to grow on the HX of my oldest outdoor unit,
since it's always in the shade, in an where there is a lot of mold etc growing..
Thanks!
