You will not see the difference. However, his willingness to CA. It will take some of the load at his cost. If your attic is the temperature of the furnace heat is at its maximum. If you have ceiling fans moved around the room, closes to near your thermostat. The effect is ca va. If you heat from the attic, the CA will be able to rotate more frequently, the reduction in bag and repair bills of the AC. Put a thermometer in your attic and read it on a hot day. The times are usually around 130 degrees. Now, the attic fan and back in an hour. You will notice a change. It is now 80 can in the attic, but definitely cooler.
Ventilation of the attic is a good thing to do, and you'll improve how your house is comfortable and completeness. There are several ways to ventilate the attic, however, and with an attic fan is not always the best way. You need to consider how they relate to existing attic ventilation (if available). For example, if you can soffit vents and a ridge of long duration of ventilation, a fan does not guarantee or advantage.
If you opt for a solar fan experience, here is how to install, with a video clip showing the process:

$ 369 for a simple attic fan may seem huge - not to be very powerful ... price $ 30 at Home Depot or anywhere else would do the same ... The cost of saving energy and solar and cons of their desire to be green is something that must be implemented)
This will sound crazy, but I (just for fun) and has 20 meters away from sunlamps Craigslist.com FREE ... What happens is that the batteries a bit rusty after getting very quickly to think for the people "" they're dead ... But all you need is a brush to clean the corrosion ... Batteries and solar cells have been good ... (Plates almost never die ...).
I connected in series in my shed roof and power a 12-volt battery and leave a LED (light) at night. You can use the same thing with an electric radiator fan car - can not charge enough ... but it is possible to obtain umphh enough to keep cool in the attic ... Project clean and very cheap:) BTW - cells outside lights are 1.2 volts each - and lights everywhere, usually two or three in series to a lamp power3.4 volts, depending on the sunlight. Connect the lighting systems in series and ends with 3-volt X number of lights ... Allow about 14 + volts to charge a car battery ... Because it is very good service, you need to spend $ 20 on a solar controller, but a cheap used car for a long time without "burning" over / under load last ... You may have to play with the number of plates to the "ideal" in the car at its best .... To maintain load
Oh, yes! Attics very hot in summer. Drawing in cooler air should make a big difference.
