But I did have one who upon moving in to a very clean apartment still had to complain about: a) dust on the ceiling fan blades b) a small amount of residue in one room from the painter that would have taken about 30 seconds to sweep up.

I live in Cali, so I don't care)-- Super quiet-- You don't have to cover up a window-- You don't have to cool the entire house if you just want to cool down a bedroom-- Some of them have swiveling blades, which I think are just awesome-- Lower BTU ones can run on 110vThe big name brand is Daikin.

They set the bulldozer and the blade raises and lowers to make the dirt the correct height.

Most large drain augers have cutter blade that will cut and not pull roots. 

It was a lot of fun but it did burn up a blade on my tile saw that was over 20 bucks.

For the standard residential system changing the filters regularly and cleaning the condenser/outside unit coil surfaces and fan blade regularly is probably all you need to do.

The investor shared a story about how they had been scraping windows at 11 o'clock at night with razor blades after painting them.

Fan blades never seem to get cleaned and it's a mess if there's a fan in the kitchen (the combination of grease and dirt on the blades cause an interesting challenge in cleaning between tenants).

In my experience, wetting, then scraping off with a broad blade, is most efficient.
