Poll on Ceiling HVAC Vents

Something that always bugs me and offends my tasteful sensibilities are homes that have ceiling vents for Air Conditioning and/or Heating and they are SQUARE vents. Square vents belong on floors or on the sides of walls. Ceiling vents should be circular and pleasant. My grandmother had radiators for heat so she had these kinds of vents when she had central air put in with the unit in the attic.

So what say you, tasteful DLers?

circular, cause I love a tight hole

I don’t give a shit.

I don't care about the shape of the vents but I have always hated air conditioning units on the roof of houses, they belong on the side or back of the house. Do they do that to keep people from stealing them or what?

Roof units are more efficient than updraft units R4. I hate the idea of the furnace in the house.

by Anonymousreply 507/29/2020

Seriously, OP?

by Anonymousreply 607/29/2020

R4/R5: Well there's air conditioning units being on the roof, and then there's whole package units where the blower, heater, cooling are all outside. I know some relatives of mine who put the air conditioning unit on the roof so it wouldn't take up space or create noise in the backyard.

On updraft units I've never seen the furnace on the outside R7.

by Anonymousreply 807/29/2020

The vents at R1 are the cheapest vents available. FFS, spend you get bills back in change when you buy one for a fiver.

Spent more money and get something that has a more substantial, less tinny look.

And those "nice" round ones you like probably looked.nice when your grandmother turned heads -- in the 1950s and early 1960s.

There are other options as well,.

Does anyone know what the, for lack of a matter word, long slits that that are on the upper wall or ceiling in new builds are?

by Anonymousreply 1007/29/2020

R8: I think I'm confused here. What do you mean by "updraft" unit?

R9: NO! Circular vents belong on ceilings, square/rectangle on the floor. There is only one way!

R10: Can we see you slit so we have a better idea of what you're talking about?

by Anonymousreply 1107/29/2020

Updraft is a unit on the ground R11. Photo 10 between the beams R11

Not sure my link at R12 worked properly.

R12: That link takes to my saved homes. Could you please try again? And it is rare, but there are package units on the side of the house as well. But most are on the ceiling. And of course, they're rare period in consumer homes, most package units of any type are for commercial properties.

by Anonymousreply 1407/29/2020

R13: That one works. And I believe that is either an actual ceiling vent or a return vent but it's definitely a vent of some sort. I'm not sure if I like it.... I do love the blue on the interior of that place. You may want to start a Tasteful Friends thread about it.

by Anonymousreply 1507/29/2020

It seems awfully thin for a return vent R15.

by Anonymousreply 1607/29/2020

R16: Must be the vents then. Though I can't imagine they're very efficient at moving conditioned air around. Some good old circular ones in my OP would do the trick and provide true comfort. Perhaps in a stylish chrome...

R13: According to this, they are called linear diffusers. Learn something new every day....

The images at R13 show *linear slot diffusers .* There may be a better name for them (and one would hope), but thatś the one I have seen.

Thank you R18 and R19.

Apologies, R18 for the duplication

I'm R13 @ R20.

by Anonymousreply 2207/29/2020

I like the idea of the slot diffusers, though Ie yet to see a domestic use where they were not sited in strange places.

This is a link to a listing from 2 or 3 years ago of newsman Jim Lehrerś historic house. In the second floor bedrooms you see them used and they drive me nuts, running sort of in the center of the ceilings. A seemingly subtle solution can be really fucking distracting.

Vents are located where they can be placed depending on the layout of the house. In most a/c installations, the compressor is outside the house on the ground for ease of service and the airhandling equipment is in the attic. In a single story home, the air vents can placed anywhere on the ceiling as long as the ducts can be routed between the beams. Two story homes need a chase - either a dedicated area for ducting or the back of a closet - in order to carry the air two levels below the attic.

Square corner ceiling vent units in the corner of the room with "L" pattern vents are the most efficient way to diffuse the conditioned air to the other parts of the room. If you used a round one in that position it would be less efficient distributing the air, sending some of it down the wall, not across the ceiling of the room. Homes don't always have a closet in the middle of the room above the one you're trying to get air to, so they tend to be routed through the corners of rooms, hence the square ceiling vents in the corners of the room. For a ceiling vent on a straight wall, a square or half-round vent with an inverted "U" shaped pattern spreads air to the three exposed sides of the vent.

The units on the side of the building (more popular in urban Europe before they caught on in the States) are called split units with the mechanicals outside the structure for lower noise and the fan in the box on the inside wall. There are also newer, narrower ducting styles that allow installation and venting through the walls rather than the ceiling, most often used in older homes where retrofitting duct work would cost more or look worse and/or work less efficiently.

by Anonymousreply 2407/29/2020

I´ve used high velocity systems in a few houses and love them. Very quiet, very comfortable, and the distribution tubes are similar in size to a vacuum cleaner hose, then encased in insulation for a 4 or 5 inch diameter flexible duct that can be installed most anywhere. Itś the least obtrusive of systems.

In some difficult settings you may need to make a vertical chase from attic or roof through a room or rooms on the second floor to reach the ground floor; normally, though, this can be tucked into a closet or some void and finished off easily, without having to build big ugly box ducts criss-crossing the ceilings.

Heating should come from the floor and A/C should come from the ceiling to be efficient. My father had a home that had baseboard heat and A/C. That was a very efficient system.

by Anonymousreply 2607/29/2020

Honestly don’t care. I’m picky about design - but personally find the round ones uglier than the square ones,

by Anonymousreply 2707/29/2020

R21: Don't be sorry, everyone posts on everyone in real time all the time. :)

R25: So there IS a gaping hole (sort of) type of vent. So we have round, square, slit, and hole vents. Kinky....

R23: I guess they wanted to have the least damage to the colonial character and charm of the place.....

by Anonymousreply 2807/29/2020

Have we established a "slit" is a vent R28?

by Anonymousreply 2907/29/2020

Of course, R29. It's surely not decorative; and "diffuser" is the output end of things, not the intake end.

by Anonymousreply 3007/29/2020

Friday Poll Bump. Shame that Slit can't be added to the poll...

by Anonymousreply 3107/31/2020

I honestly don't have a preference.

by Anonymousreply 3207/31/2020

As an anal-retentive OCD design queen, I have strong opinions about all of this. The first one being that there are never enough good design solutions for mundane things like air vents - and I mean it. The 'builder' rectangular vents that the OP speaks about are indeed hideous and cheap-looking, and the round ones look outdated. Linear diffusers only work in some homes - mainly modern/contemporary homes - as R23 points out (what a house!). The high velocity system that R25 shared looks decent from a purely aesthetic point-of-view. But STILL - not enough good looking options. That's why designers are always trying to hide them and why you almost never see one in a design magazine spread - they photoshop them out!

by Anonymousreply 3307/31/2020

R33: I prefer classic over outdated when it concerns the round ceiling ones. They're unique since so many homes either have the rectangles on the ceiling or just have the floor ones (which are terrible for air conditioning cooling anyway, but that's a different thread).
