summer fan
I have a summer fan on my forced air furnace. It can be turned on to
blow fresh air into the house. I am thinking about replacing the fan wih one that will turn blow in both directions so that at night I can blow hot air out of the house. My brother has a whole house fan that cools the house very well. Does anyone have an opinion about whether reversing the summer fan will have a similar effect? |

Your ducting is able to rout outside air inside? If so then you have
reduced your winter and summer efficiency and waste alot of energy. You realy should seal it shut. |

Where does this summer fan get the air from? If you mean to just run the blower on the furnace, it will do nothing. If it is ducted to the outside, it may help a little, but will not do what a whole house fan does. In order to cool the house, you must vent out the hot air and suck in cooler air. I don't know what you have now. |

summer fan
The house is supposidly air tight so a duct was installed from the outside of the house to the interior closet that has the furnace. In the winter the duct stays shut unless the furnace turns on. However, it is wired to override the valve that shuts the flap with a toggle switch so that the duct will remain open all the time, so that in the summer, the theory goes, I can use the fan on the furnace to pull fresh cooler air in. It doesn't work that great. The whole house fan in my brother's place is in the ceiling of his hallway and pushes household air into the attic space. Cooler night air is pulled in, I guess, cooling the house very nicely. I am wondering if putting a fan in the duct to pull air through the registers out through that duct will work like the whole house fan, or if somehow this system can be modified to remove warm air from the house in order to pull cooler air into the house through open windows. Unless there is a breeze, the cooler outside air doesn't cool the inside of the house that great and the summer fan doesn't add enough fresh air to make much of a difference. Will rigging it to work the other way, pushing warm air out work better? It seems like box fans and attic fans are wired to pull the hot air out of spaces and the cooler air is pulled in, passively so to speak. |
