Just a question regarding the blower motor on my furnace. I

Well needless to say that makes a huge difference as the
compressor isn't
needed as much.
My concern is will this shorten the life of the motor? And, is
it ok to
leave the fan on 24/7 for 2, 3, 4, 5 days? My thinking is to
leave it on
for whatever the duration of the heatwave. Correct?
Sounds like a silly idea. The motor will get its life shortened,
and
your electric bill will get its dollar amount raised. Also, all
energy put into that motor to spin it eventually becomes if
you've
had physics you've already guessed it heat. Heat that will be
going
into your house.
Chris, you and Travis hit the nail on the head; the blower adds
heat and
will run your electric bill up!
If you want air circulation use a large 20" floor fan in the areas
you
will be in; it uses a lot less electricity and produces very
little heat.
If increasing the air circulation with a floor type fan allows you
to
set the Rm TH to a higher temp - that will save on energy costs
and
compressor run time.
Running the furnace blower motor 24/7 will add to much to energy
consumption and add motor heat to the conditioned space. (Losing
equation.)

agreed, you want to use a fan, not your AC blower.
