In my first year in my townhouse with no AC (NE facing), using air movers, the furnace fan on 24/7/exhaust fans on and windows open in evening etc. for hours before sleeping, house would still be sweltering hot until like 2-3 AM when the temps finally dipped into the low 20s.
At least for what was in my old townhouse unit, it didn't move enough air to be considered a poor mans AC. I wish it had been good enough as a poor man's AC, but I had no choice but to install by next summer AC to avoid peaks of 30C+ temps in the town house during the summer. It's not like it was going to replace a heat pump or HRV for air movement/exchange.
