Do you truly think so?

RayB:
Believe it or not there's no means to close the first floor vents other than by physically obstructing them (which is what I did in winter to help move more heat upstairs).  

I've seen window units meant for 1 room for as cheap as $99, btw.

To answer Blanka, lower Canada (Toronto), 1950s building, flat roof, asphalt roll, no attic, insulation unknown, brick exterior, new double pane windows throughout, forced air mid efficiency...  ??

Blanka:
The heat probably comes in through the roof or through the windows then. Brick is usually a good thermal damper. Always best to tackle the source instead of trying to fight the problem with cooling.
So the best bets are:
- Renew roof insulation. Today's insulation is so good, it always pays back on gas-bills if the current insulation of the roof is 10 years or older.
- Add exterior shades to the windows of the top floor.
- Make natural ventilation possible with windows to open. Balanced mechanical ventilation is only interesting for winters if it uses heat recovery from the exhaust pipe.
- AC is NEVER needed, not even in Dubai! We lived without until the 50's, so check building habits before WW2, and there is always a local working solution to fight heat without AC.

No you haven't.  You've seen window units meant for one 8' x 8' room in Alaska for as cheap as $99.
