Window AC and Exhaust cooling

I have a 24,000 BTU window AC unit that's suppose to cover the whole house. (House 1000 Sq Ft) Unit Covers 1000-1500sq ft. My question is I plan on installing the unit in the front of the house hoping it will cool the whole house do I need to get a window Exhaust and install it at the other end of the house for the air to travel? OR Will the unit ac exhaust be good enough to cover that job?

No....the exhaust feature on a window air conditioner is designed to discharge a certain percentage of your "just paid for" cool air. Normally, you'd only use that exhaust feature when the unit was in fan only mode (not cool)
A window air conditioner will not usually cool a whole floor by itself because cold air settles to the floor and doesn't travel well. Most people that use a window unit for a whole floor will put a floor fan half way thru the house to increase air flow. You would point the unit up into the uncooled areas and the air would travel and fall again. I see you live in Florida. You need air conditioning there.

On edit: you don't really want any type of exhaust fan to move air conditioned air as it would be drawing cool air out of the house. (and more than likely drawing in warm air)

Thak you so much for replying. The area where i'm putting the ac there is a ceiling fan 4ft away from it and 2 more 12ft away. I also have a floor fan in between the 12ft area fans. So do you think it's best to have the 4ft ceiling fan in reverse blowing the ac air up and the other 2 blowing down then use the floor fan to blow in the halway?

By the way i'm using a window ac because my central air broke down and it cost $2,500 to replace.

You'll need to experiment with the ceiling fans. The one nearest to the a/c might not be of much help.

ok I just hope the air can reach the back rooms with the floor fan pushing it back there.
