Whole House Fan

Need help if anyone has installed one of these before.

I got the sizing down but I have high ceilings in certain parts of my house. I'm putting the fan on the high ceiling between the living and dining rooms.

My concern is that our master also has high ceilings and our door is at normal height (7ft?). Will the fan be able to pull the hot air out of the ceiling in our room? I'm thinking I need to put a second small fan just for the bedroom.

I attached my half ass sketch if it helps.

Do you have a ceiling fan in the master? If you do that would mix the warm air down and allow it to be pulled out by the whole house fan. Without it, it will just take a lot longer for the air moving through your master to self mix with the upper air and cool that area.

Your comfort level will be determined by the air down ar the level where you live. To exchange air in any room will require a supply of outside air, an open window will do, and that flow won't take long to cool the room. As Tumble mentioned, a ceiling fan would be good.

Your climate zone is not listed in your profile (location) so we don't know what that outside air is made out of, hopefully cooler evening air.

If you are also using ac, a whole house fan can have the downside of filling the house with humidity which is absorbed by everything. The house will recover once the ac is back on but it takes a little longer.

No ceiling fan in master. We do have a pendant mount light which I could change to a ceiling fan.

I live in Hawaii. My main problem is my house location on the street. It can be windy outside but nothing inside the house. And it always feels cooler when I step out side.

I do have a split unit AC but I wouldn't be running both at the same time. Fan would be more for overnight when its cool enough to not need the AC outside but inside is terrible.

Think I'm just going to chance it with the one fan between the dining and living. If its not enough I'll entertain a small fan for the rooms.
