I live in Colorado, and my swamp/evaporative cooler was poorly placed
in the basement of the house. Rather than using a combination of fans
and open/closed windows to get the cool air upstairs, I'm thinking of
ducting the cool air into the heating ducts, which are accessible and
close to where the swamp cooler air comes in.

Anyone have experience that would encourage or disuade me from this?
Suggestions or tips much appreciated!

In Arizona, people sometimes had a problem with mold growing in the ductwork
because of the moisture introduced. So separate ductwork for the
evaparative cooler was preferred. You'll still have to open windows to vent
the air unless you put upducts in the ceiling to vent it into the attic.
What would happen if you installed a whole house attic fan in the ceiling of
a hallway and used that to pull the cooler air from the basement evap cooler
upward?

How does that help? Wouldn't mold grow in the new ductwork eventually
if not sooner, if it would grow in the old ductwork?

Where does the cooler get it's input? I am in CO too. The cooler
located on the roof and ducted down. A cooler has to be at the highest
location in the house sucking in dry outside air. Then it has to exit
though windows at the far side of the cooled area.

Mine comes into the center of the house (ranch) and then I open windows
at both ends of the house. If it were two story I would have it come in
upstairs and then open windows in the areas I wanted cooled the most.

A good cooler needs a lot of air. The heating ducts are too small to
get that kind of air flow.

So at a minimum you need to relocate the cooler to a window so it pulls
in outside air.

The heating ducts are probably sized too small to handle the air from
the cooler. You would get a lot of noise from the registers because the
air velocity would be very high. Also, you'd probably want some dampers
and interlocks to prevent the cooler and furnace from operating at the
same time because the cooler could force CO into the living space.

Bite the bullet and put that cooler on the roof where it belongs. If you
want to get fancy, add properly sized duct work in the attic to
distribute the cool air. Put in some Updux cans and you won't have to
bother with opening windows when the evap cooler is running.
