How To Keep The Third Floor Cool

I would recommend adding a small additional system for the third level.

How to keep the third floor cool.

Place a large fan at the base of the stairs the floor below main floor and position it to blow air up the stairs. This relatively new technology is extremely quiet comfortable and energy efficient. If the thought of getting into a cold bath makes you sweat fill it first with. Placing a cold wet washcloth on your neck or wrists drinking something ice cold to stay hydrated using mint or menthol.

Extend ductwork up there to connect the central ac. Wearing lightweight loose fitting clothing taking a cool bath or a cold shower. Try to keep yourself cool inside your house and this is not at all a bad idea. By splitting to force air to the third floor you are removing from another area.

Not if the thermostat is on the 3rd floor thus making the ac run constantly because it is hot up there so yes keep it cool so that your 1st floor is not freezing because some dumbass put a thermostat on the top floor. Sip ice drinks and keep cool clothes to strong pulsed areas like neck and wrists that will make you cool and comfortable in this summer. Windows on second and third floors can add a lot of light and character to your home but they can also let in a lot of heat too. A less expensive option would be to install a window air conditioner unit.

Central air for a third floor first of all adding new ductwork to your home is expensive. Keep a cool bottle just beside your bed and drink it in the night whenever you will feel warm and humid. Keep the blinds curtains upstairs closed or at least close the blinds on the side of the house the sun is shining on. Unfortunately none of these are ideal.

What if you want all areas heated or cooled simultaneously. Be sure not to close off too much downstairs as you will risk freezing up your system. An answer without a question is meaningless. This will keep the sun from heating the top floor even more.

Your first step should be to get that 3rd floor room better air sealed and better insulated and go from there. The most ideal option would be to look into a ductless hvac system. Or use a window or portable air conditioner. In the evening and night you can open the shutters and windows to let in fresh air.

Consider having yours insulated or replaced with sealed double insulated windows that have special layers to block much of the heat gain that comes in through windows.
