troll-feeding senile Yankietard, blathered again:

"Single units" are typically window shakers and they get sold dirt
cheap, You can find higher efficiencies in window shakers, wall packs
and package units but they cost more.

So, for how long are you senile idiots still going to go on like that? Until
the troll is fed up with you again? Just HOW senile are you? tsk
