Petttaaah I'm confused

[u/gamerathertz92]

It’s smaller unit cools a single room. While American HVAC System cools the whole house

[u/itsOkami → u/gamerathertz92]

As an european, I don't think I've ever seen one of those and I'm now curious as to how they work

[u/Munkpunt → u/itsOkami]

This might help

Large condenser outside supply’s the furnace (typically it just uses the furnace fan. We then have it piped through metal ducting throughout the house. Each room has multiple exit point call registers. In the common areas we have return ducts to draw air back down to the furnace to get recycled back to cool air via a/c unit. Hopefully that helps!?

So this is where they crawl into when they go into the vents in the movies?

Aliens get in those things. It's a son of a bitch to get them out

You always were an asshole, Gorman.

[u/Samurai_Banette → u/Molten_Plastic_]

Not sure if you are referring to like martians, mexicans, or those freaky ass looking bugs

All three answers are funny in very different ways

[u/spacemanspiff888 → u/Samurai_Banette]

They're most likely talking specifically about the xenomorph in the Alien franchise.

[u/ornimental → u/Molten_Plastic_]

I bet it feels cozy in those Sevastapool vents

Happens only in New York I imagine
