As a Midwesterner, it is absolutely bonkers to me how common it appears to be for HVAC systems to get installed in attics.

Don't do that. Stop doing that! WTF?

That's bad enough, but then you go and run the ducts up there, too?

Y'all.

If you keep the system and the ducts within the space you're trying to heat and cool, you don't have to account for any losses, now, do ya?

Put the air handler in a utility closet. Run ducts /below/ the ceiling. Enclose with soffiting if you must.

The end.

@TechConnectify There's not enough room below the attic in my house to run the ducts. we'd be hitting our heads on the ducts if we did that. Of course, we only have one duct since we're in the desert west, and that one duct runs from the roof evaporative cooler. Heating runs under the floor in most houses I've been in. In my case, hot water heat embedded in the concrete slab.

@kazriko Do you have lower-than 8 foot ceiling or are you imagining some sort of monster duct?

Because you can totally just drop the ceiling by about 10 inches along the perimeter and run an 8X24 rectangular trunk.

@TechConnectify It's somewhere under 8 feet, but a bit over 7. Any lower and I wouldn't want to invite any tall friends over.

@kazriko Even if it only went around the perimeter?

This is purely academic, btw, I'm not saying you should retrofit your home. Mini-splits are generally a better option for that (with some caveats) but I'm just trying to challenge norms, here.

@TechConnectify That would probably still interfere with some of the windows I think. And right now, we only have a single air intake that is in the hallway, and you just crack a window in any room you want the air to flow into.

@kazriko You know your home better than I do, definitely.

Again, just trying to push people's minds to somewhere else.

The section in this article that reads "In recent years, energy-saving designs have sought to include ducts and heating systems in the conditioned space." is hilarious to me since, y'know, we figured it out half a century ago. I'm baffled by how revelatory the concept seems to be.

@TechConnectify Well, for an evap cooler, the duct is only going through the attic because there's really no way to get it down from the roof without either going through the attic, or outside the building. A lot of people I know have switched to Window units lately because the window units have gone from huge, to something that fits largely flush to the outside wall.

Other than ducts running from stuff in the house to the roof, and a couple of network cables, there's nothing up there.
