Here in Seattle, most homes do not have air conditioning as our summers are mild. However, summers are continuing to warm. Therefore, as I was replacing the mechanical components (including the supply plenum, return mixing box, and the furnace, air handler and filters), I installed the brass hose barb fitting and a pass through for a chiller line set. Under my water heater which is besides this area, I have a 3/4" copper pipe that runs outdoors for water heater overflows. I added a tee which I connected to this fitting. That way, if I ever put in a coil, the condensate hose could run a mere 2-3' to this fitting and have the water run out of the house (furnaces and water heaters are often installed in garages here in Seattle as there is usually no basements - thus no drains). I placed a red cap over the end and stainless hose clamp on the fitting until I attach a hose in the future.
