Does anyone use a portable air conditioner (not a window unit) to “boost” the coolness of their top floor? I have a 3 story rowhouse with central AC. The thermostat is on the 3rd floor. I keep all the vents on the first 2 floors closed and covered and am comfortable with the thermostat at 78-80 – but the folks up there need it set around 76 to really be cool – so I am too cold down here.
I have good windows and thermal shades to keep the sun out. I tried a window unit up there, but the only good window is south facing & over a roof so despite all sorts of sealing attempts, lots of heat pours in around the unit, defeating the purpose.
I’ve read about 100 online reviews of 100 models of portable air conditioners and am more confused than ever. Has anyone actually used one for this purpose?”
