I like to look at where sayings and phrases come from. Where did we get the term "double whammy?"
It means a double setback or a double blow. But when did it make it into our vernacular?
Apparently Al Capp used it in a "Lil'Abner" cartoon in 1951. "Evil-Eye Fleegle is th' name, an' th' 'whammy' is my game. Mudder Nature endowed me wit' eyes which can putrefy citizens t' th' spot!. There is th' 'single whammy'! That, friend, is th' full, pure power o' one o' my evil eyes! It's dynamite, friend, an' I do not t'row it around lightly! ... And, lastly - th' 'double whammy' - namely, th' full power o' both eyes - which I hopes I never hafta use."
That's quite the explanation! I don't know who is speaking to whom, but the teacher in that person just came out!
Well, the words "double whammy" came to mind when I saw this. It is certainly a double blow!
This is a 1960's apartment building, with one unit stacked onto another, converted into condos in 2005.
The vent on the right services the dryer in the unit I was inspecting. That dryer is literally 15" from that vent.
The vent on the left services the dryer in the unit below!
That's two dryer vents blowing right onto the AC compressor. I have never seen this before!
That is too close. Why? I have posted on this before. That post shows what can happen to an AC compressor that is too close to the dryer vent.
This unit is drawing in air. If that air is laden with dryer lint (OR A DOUBLE WHAMMY OF DRYER LINT!) the compressor will draw it in.
Over time that will clog its ability to suck in air and dissipate heat as it compresses to create conditioned air.
The rule of thumb is that any compressor, AC or heat pump, should be 12' or more from a dryer or kitchen vent. That way there is little chance for accumulating lint.
My recommendation: pay attention to where the dryer vents! Your compressor will love you for it.
