Hi,

I have a two story house with vaulted ceilings throughout. I had AC
put in last year, but the upstairs doesn't really cool down. The front
of the house has the biggest windows, and is West Facing, so it gets
all of the afternoon sun. Last year, I also replaced all of these
windows with much more efficient windows.

However, I can't get it below 80 degrees upstairs. And this can often
be when its cooler outside.

In examining my options, I noticed that I have NO vents on my roof. I
have all vaulted ceilings, so I don't have an attic. I do have some
soffit venting on either side of the slope of my roof.

Can I put turbine vents on the roof? Will this make a difference in
temperature for those upstairs rooms if I can cool the space between
the ceiling joists and the rafters? Again I have NO ATTIC.

Really, what I'm looking for is a way of removing that hot air from the
vaulted ceilings in the summer.

Any suggestions? Turbine vents appear to be an easy solution. Will
cooling the space between the roof and the ceiling help in cooling the
room below it?

- Thanks in advance,

Todd

Maybe. Soffitt venting might be useful, _if_ it's of adequate inlet
area _and_ air coming in there can move up inside the roof deck and
escape somewhere. ,

Insulation between ceiling and roof deck could block airflow, unless
spacers were installed between insulation and roof deck. You mention
nothing about this.

Ridge vent could work, and is simple, elegant solution, depending on
stuff mentioned above. Thermostatically-controlled fan(s) with
mushroom-looking enclosure would work.

Ask locally, and/or visit big-box.

But how is it that venting the this space will help remove the heat
from the ROOM below it? This is what I don't get. I understand venting
the soffit, but I don't know how that will allow the heat in the room
below (with the vaulted ceiling) to cool down.

Any thoughts on this?

- Thanks,

Todd
