Concerning the electric thermostat that controls my Trane furnace and
air conditioner, if I change my fan switch from "Auto" to "On" (so
that it runs continuously), is it pulling in air from outside or just
circulating the air already in the house? In other words, is running
the fan a good way to cool the house at night when the air temp.
outside is a good 15 degrees cooler than inside?
You already got the 'bad' news that it only circulates house air but..
The good news is that running it 'on' will significantly delay the
start of the AC. Much cheaper to run that fan than the AC. In my
case, when it becomes a bit uncomfortable in the house, putting it
"on" will keep the AC from running for another hour or two if it isn't
too hot outside.
Harry is right. Turning the fan "ON" will circulate the cooler air
that sinks to the lowest level of the house and cool the upper levels
while heating up the lower levels. So, it depends on where the
thermostat is located. In my 4-level split, the thermostat is on the
third level up, and running the fan "ON" cools it down about 2 degrees
while heating up the lower levels, and does delay turning the
compressor on by an hour or two.

You and Harry are clueless. As Noon said, it will raise the humidity
level. Also, trying to pull that cool air from the basement will
reduce the ability of your system to be able to remove the warm air
from a first and second floor. Air will take the path of least
resistance and you will remove no warm air from your upper levels.
You two should really get a clue before you start babbling
And who said anythign about pulling cool air from the basement? Yes,
I mentioned it as a _possible_ thing to try but that has nothing to do
with what either of us has attempted to explain to you. But then your
handle pretty much explains you 'Bubba'.
Reading comprehension problem there is there? Read what we are
actually discussing. My mention of the basement was a FUTURE (caps
for the reading impaired) possibility. We are discussing what is
Did you just re-read the first 2 sentences of your paragraph just
First you ask "Who"? and second you said it was "You"?
I thihk that, and your previous post has shown me all the competence I
ever need to know about you.
