would an attic exhaust fan even out the temp of the house upstairs and downstairs ?
Feb 10, 2008 by andrew | Posted in Maintenance & Repairs
I have a 3yr new house and during the summer there is a difference of about 10 degrees between the two floors . The thermostat is downstairs and i live in florida . Would an attic fan make the upstairs cooler and even out the temperature. the heat in evening is incredible .
Yes it would.Use a small electric fan/blower and not just a ventillator. Draw the heated air out of the attic and exhaust it outside. Cooler make-up air will drawn in from any intended or unintended source.

Maybe close off the downstairs vents slightly so more A/C goes up.

Yes, the attic exhaust fan would get heat out of the attic which would then help get heat out of the rest of the house.

Better insulation will help the difference out more that an attic fan! An attic exhaust fan is very good though at circulating the air in your attic and reducing the humidity build up. With your house being that new, i would venture to guess that everything is up to code!

If you have open access to the house below from the attic via a ceiling grill or open attic hatch, cooler air from the lower parts of the house would be drawn upstairs, you may be able to achieve the same result by closing all the heating/cooling vents on the lower floor so that more cool air is delivered upstairs.

They can cool a house to outside temperature in a few minutes. Even in homes with central air conditioning, using the fan in the cool of the evening can cut your electric bill substantially plus refresh the air in the house.

yes deffinately, heat travels up and gets stuck in the attic. The fan would release this heat making room for more heat to come up from down stairs. I think it will always be a little hotter upstairs but this will deffinately reduce the over all heat of the house.

Does an exhaust fan in the attic of a home, help the central air to function better?
Jul 29, 2006 by C J | Posted in Maintenance & Repairs
This home is beautiful, in great shape, supposedly the central is working fine. There is a giant exhaust fan in the attic, it's not working. I've been told that the fan working would cool the house off tremendously. Does anyone know if there is any truth to that?
Yes. A whole house fan draws the warmer air (which rises) out the attic, and draws cooler air into its place.
An attic fan is a very smart investment. By the way, an attic fan can often keep a house fairly cool without even running the air conditioner.

Best way to vent an exhaust fan over the stove, outside or into the attic?
Jan 28, 2007 by Pilotbill13 | Posted in Maintenance & Repairs
Should the Range vent fan exhaust into the attic or to the outside?
It should definitely be vented to the outside through the recommended size metal ducting in the shortest distance possible. It must not be longer than the equivalent of 30'. Every 90 degree bend = 3'. The hood where it goes through the wall = 3'. If it is longer than the equivalent of 30' it will not vent properly and clog up from the grease and oils and dust and dirt that will cling to the walls of the ducting and cleaning would be required on a very regular basis.

Bathroom Exhaust Fan without Attic?
Jul 25, 2007 by Eric | Posted in Do It Yourself (DIY)
I am needing suggestions. I have a downstairs bathroom that need an exhaust fan put in. There is a light in the ceiling, however there is no way to get an exhaust duct in without ripping out the ceiling. I am needing this for moisture removal due to shower starting to mildew the ceiling. The bathroom is on an exterior wall of the house on 1st floor. Would it be better to install something high in the wall venting outside or is there another option for a ceiling installation?
If venting out the exterior wall, do you simply use something like a dryer vent would go through or is there something different for the bathroom vent?
You can vent from the wall, especially if this is close to your shower. You can use whatever you like for the outside closure, dryer style will work fine. For added protection from small varmints, you may want to install some 1/4" screen material to make sure something doesn't try to crawl into the ductwork.

Whole house fan vs. attic exhaust fan?
Jul 20, 2006 by Rod N | Posted in Do It Yourself (DIY)
Does anyone have any thoughts on the best way to cool a house off in the evening. If you have either of these devices, could you tell me how well they work? Thanks, I appreciate your help.
a I have both, but I would have to say the whole house fan is the best for controlling the temperature after turning your a/c off. It pulls the outside air in through open windows and doors then pushes it into your attic and out the gable and or soffit vents, bringing the attic temperture down to the outside temperature and of course your indoor temperature will do the same. Yes they do make some noise so I wouldn't try getting the cheapest one you find. make sure it has adjustable speeds. As far as the exhaust fans go they do help keep your house cooler by bringing outside air through your attic, but after you wish to turn off the a/cunit it doesn't give inside the house any cooling affect,and usually is set for 90 to 100 degrees wich means it will be off when your trying to use it in the way your discribing.
