I live in a Condo that has 3 floors. The HVAC is in a closet on the
first floor where the thermostat is. I have seen home systems that have
multiple air pipes coming of the HVAC to feed zones but unfortunately I
can can't do that since there is no basement or room. Are there other
options to put something like inline air monitors to send more air
upstairs when an occupant is there? The 3rd floor is probably 8 degrees
hotter than the 1st floor on hot days (> ).
This is what we do with one big room in the attic, but not an AC from
Sam's Club (I won't buy from Walmart), instead an AC from a local
applicance/home furnishings business. Works great! Retrofitting the
returns would be an incredible nightmare.
Many of my customers live in condos and townhomes and I hear of this problem
often. One of the biggest contributors to this is the poor location of the
returns. In one particular development with two story condos the only
return for heat and A/C is downstairs at the base of the air handler.
Consequently no hot air is removed from upstairs.
After exploring other options with HVAC contractors regarding one of my
customers in this predicament, everyone agreed that the only viable option
in this case was to install a supplemental exhaust fan that vented into the
attic. There was no way to install return ducts without tearing out the
ceiling and walls and no one was sure if the space would be available to do
so. I installed a remotely located 440 CFM quiet Panasonic fan with a 16" x
20" filter vent on the wall near the peak of the sloped ceiling. I told the
customer that she will need to leave a window open for air flow. She called
me a few weeks after I did the installation and told me what a difference it
made in her bedroom. When the fan is on she opens a downstairs window so
the outside air is cooled before it makes its way upstairs and she has been
able to raise her thermostat setting.
Other options you can possibly consider is an attic ventilator fan or a
whole house fan.
Others have posted some good info. Check that your air filters are clean and
not restricting the air flow. See if air flow increases when the filter is
removed. You could tie a streamer to the vent to help judge whether flow
increases. Try running the circulation blower continously for at least 24
hours. You can't just cool the upstairs when someone is up there as home air
conditioning systems do not have that kind of excess capacity. What you need
is more air flow to the upper levels. Booster fans in the ducts might help.
Be sure you have a good clear pathway for air to get back down to the air
return inlet; no closed doors, etc., in the way.

call some local HVAC contractors
The big problem is that heat rises. So, the building needs more AC on the
third level. Sometimes this can be done by partly closing the vents to the
lower levels. Other times, closing vents creates more problems than it
