Would it be feasible and reasonable to install an attic fan in this part of the county?

Well, you are not really supposed to mix attic fans with ridge vents (which you probably have), but in some instances they would help. Better off blowing in some good insulation first and see how it goes.

We have one in the garage that blows into the attic. Was here when we bought. There's two turbine vents up to that would release that same air, creating circulation up there. Not sure of the effectiveness of it but I know several people who have attic fans that blow from the attic, into the garage. Some has it wrong. Would be good to hear opinions on this subject.

I'm curious what's "wrong" with a ridge vent and a attic exhaust fan...

What I'm saying is if my house blows air into the attic and someone else's house blows air out of the attic, it would seem one is counterproductive. Just don't know which one.

Oh, I understood what you were saying - my question was more towards HarborRats statement that it's a bad idea to have both a ridge vent and an attic fan. Sorry, I should have clarified.

In our current house, we have a ridge vent and a temperature activated attic exhaust fan.

Harbor Rat is correct. Ridge vent works in conjunction with soffit vent to allow air flow intake at the soffits and through natural convection to exhaust at the ridge. The fan would disrupt this by sucking air in through the ridge vent and out through the fan thereby reducing the uniform flow from the soffits. Mark

So would mine be working to enhance the proper air flow direction, since it brings outside air in from the bottom of the attic and forces it upward toward the ridge vents or should I not use this thing?

My exhaust fan only kicks on when the temp is over xxx degrees in the attic. I forget what they set it at but wouldn't keeping the temperature down up there be a good thing? The exhaust is on a thermostat so it's not like it's constantly running.

Don't see how that could be a bad thing? I'm not being argumentative, it just seems to me that it'd make sense to keep the temp down.

Normally, with proper insulation above your ceiling, you're fine with good clear soffit vents and a ridge vent. Most all roofs are designed to work using that method, so if you already have that you should be fine. That said, a power roof vent that is temperature controlled to turn on when you attic temperature rises above a set point, then you are reducing temperature in the super heated space, which is supposed to help your AC maintain the inside temperature. Your AC is not really designed to operate well above 100 degrees, most ACs are designed to operate within a temperature range, and a huge number of factors are calculated (exterior walls, exterior wall insulation, windows, doors, number of stories of your house, etc...) to determine the sizing. Now, that said, if you have ((adequate insulation)) it should help reduce the impact of the super heated attic space on your home, since heat rises (as others have noted). An attic exhaust fan, will help do that, and it may help reduce the work your AC has to do on super hot days (over 100 degrees).

That said, I had one on my house in MD for years, and it worked on those really hot days. I could hear it running. But still on the summer months when its hot, my electric bill was still a lot higher than normal (my wife likes it cool), so I can't help you on the off-setting costs of running the fan vs. the power used by the AC.

That said, as others have noted - make sure you have proper air flow, and good insulation. If you decide to add insulation, make sure they add adequate baffles to keep the air flow from your soffit vents (where they could cover them with the added insulation) to the attic ridge vent.

That said, I'm thirsty all this hot air has me parched - time for a beer!

That said, (see how I did that)?
