It's rather basic. I don't see how that would really help you. All you do is cover your vents and open the highest window in the house. You'll feel it cool down very quickly

You probably have to vent out the hot air from the third floor. It'll produce a vacuum that in turn will allow the colder denser air to come up to the higher floor. It seems counterintuitive to have a fan in the window blowing out air when you have an AC running but you have to remember that hot air is acting as a force that prevents the cold air from making it's way through. That hot air has to go before cold air can take it's place. Does that make sense?

@@walkingmonumentyup makes sense. It’s like the car windows effect. You get into a hot car then it’s best at first to open the windows and have the AC full blast. Let the hot air out. Same for the house. Open upstairs windows initially. Best to turn AC on at night. Avoid using during the day. Stay downstairs. Go to the mall.

Install it at night. It should be much cooler!

Emma B3ar I only give out information

@@walkingmonument ok lip-smacker

Exactly! Believe me, you will feel the difference immediately. The other thing to do after you've done that is to blow out hot air from the uppermost level of the house. It seems counterintuitive to be blowing out air when you're trying cool the house but hot air rises and then it acts as a wall that prevents the cool air from reaching the top floor. You have to get that hot air out.

Look at termites. They have an exhaust that is open at the top where the hot air flows out of. But cooler denser air is able to rise up and they are able to keep their home a constant temperature. Neither too hot or too cold

All cold air should go directly upstairs. The cold air is literally heavier so it will naturally go to the lowers levels anyway. Basements are always cooler even without ac. Thats because cold air sinks. That's why you don't want to waste cold air conditioned air into the basement. It should shoot straight to the top. Hot air on the other hand should always start in the basement because hot air rises and naturally warms the house. If you have a warm basement, you will automatically have a warm house. If you have a cold upper level you will naturally have a cold lower level.

@@walkingmonument hey bud , I live in Florida and have the same issue with a customer's house. 1st floor ice cold and 2nd floor as your walking upstairs you can immediately feel the difference. The temp coming out of the vents are 56 degrees in each room upstairs but rooms still hot. Seems like air flow not strong enough. We use flex over here. Do you suggest the Same thing ?

@@pnajera3938 I recommend that you close vents on first floor. There's no need to cool the first floor. You have to vent the hot air out of second floor simultaneously. Hot air is preventing cold air from taking over the space. Think of a hot air balloon. Hot air is making the balloon rise. It's a force. The air around the balloon is always cooler than the air inside the balloon. And even though the air gets colder as go up and you have more cold air surrounding the balloon than hot air inside the balloon, the hot air doesn't immediately turn cold. It takes a long time for the two temperatures to even out. The second floor of your house is like a hot air balloon and if you want the balloon to come down, you have to let the hot air out. It's the same with temperature. If you want the temperature to come down, you have to release the hot air. It's that simple

Put them back. It's meant to be a solution for the heat of summer. Most people have their heating sources in the basement, whether it be a hot water tank or a furnace or like us, a wood burning stove, so the basement doesn't ever have a chance to get too cold. Plus the basement temperature has less fluctuation due to the constant found in the ground. Average basement temps are between 50-60.
