You should be able to get an inline booster fan for the

An option I would definitely consider except I haven't been able to
find a "temporary" booster fan, and will not go to the time and
expense of installing something in what is someone else's house. The
HOs do not seem concerned about mitigating the problem, so the wife
and I will adjust accordingly.

The good news is the HVAC guy from the property management company
told us we stand to have lower cooling bills than average this Summer
since cold air pushed to the second floor will come down the steps and
keep the first floor temperate.

We just have to have sweaters and blankets available on the lower
floors in the Winter...
