  Anyone have them or ever have them?
  
  2nd floor gets much warmer.....trying to cool the upstairs equally, 1st floor feels good, the upstairs gets hot!
  
  Any suggestions?

  In our last second home we had an attic fan. It did work but, it was loud and costly, temp setting was high but it ran all the time. The cost of operation vs the some what cooler upstairs … not a good deal
  
  Few hints to help, we have the same problem in this 75 year old home presently ..
  1. Clean out your attic from having a lot of stuff stored in it.
  2. Roof vents helps
  3. Check your insulation
  4. Close off some of the vents down stair to force cooler air up stairs</SPAN>
  5. We put ceiling fan down stairs to keep the air moving
  
  6. We put two ceiling fans upstairs to circulate the air &#8230; big help </SPAN>
  
  I will never have a attic fan .. ever again</SPAN>

  I'm a fan of Attics. Hope this helps.
  
  Actually my Aunt and Uncle used one for years to cool their house. Didn't really cool so much, but there was some good airflow within the house while it was running.

  Nothing stored, just insulation

  Are you taking about ridge vents on top of the shingles, have those abs soffit.

  I was looking at solar power/electric and has thermostat/humidistat. Only runs when gets to certain setting.

  Do you have soffit and ridge vents? A proper passive system with proper attic insulation should be sufficient in Ohio. Usually an attic fan is a crutch for the passive system or the insulation being insufficient.

  I replaced one that is mounted in the roof a couple years ago --- new ones do not need lubed, which is good. It has a thermostat so it pops on whenever it gets, say, over 95 degrees in the attic. Sucks out the really hot air from the attic which puts less pressure on your second floor temp's. A real good idea for less than $100.

  Our house has one, we run every once in a while for no more than twenty minutes at a time.

  Works really well if put in the upper hallway and pulls cool air from down stairs up. Have a timer controller switch in hallway and set for 1/2 -1 hr. You can regulate the breeze in one room by opening only those windows in that room and it sucks the cool night time air up thru the room your in upstairs. Great for the Spring and Fall when it gets hot in the house upstairs and cools off outside. LJ's right in that the attic has to have good vents for it to work. A fan in the roof of the house is a waste. Has to be in the hallway or bedroom upstairs.

  My dad built one. Has three ~12" fans on a piece of plexiglass that sits as a replacement to the attic window. Only kicks on when it reaches a certain temperature.

  Love the ones in the house that get the air into the attic. Really cools the house down in a hurry. Make sure the windows are cracked before turning it on!

  We put one in when we build the house - it's mounted in the ceiling of the upstairs hallway. The builder added more vents to the ridgeline and eaves accommodate the air flow, and we later added a muli-speed control and an airtight cover to keep the heat from leaking out in the winter. Absolutely love it - on the high setting, it can replace the air in the house in less than two minutes. With a little air moving, the house is usually comfortable to about 80 degrees if it's not terribly humid, and we can save 30-40 AC days a year as a result.
  
  Like Ironman said, if you turn it on without any doors or windows open, it pulls all the outside air into the house through the water heater vent, which blows out the pilot light.

  We put one in a few years ago. I guess it does help some with the cooling not a big fan. I am not sure but the guy that installed it said it will help make the shingles on the roof last longer. I guess only time will tell
