cool enough -

the office is cool enough we have the swamp cooler going since this morning. We can do this because our humidity here is so small and the air so dry that it actaully helps to run it.

Mine at home needs adjustment - the boys have to get back up on the roof and adjust the water float- so it doesn't overflow. ( kind of like the toilet float LOL )

Advantages of an Evaporative Cooler

	An evaporative cooler use as much as 75 percent less electricity as air conditioning does.
	An evaporative cooler costs about half as much as an air conditioner that will cool the same sized area.
	An evaporative cooler operate on 120-volt electricity, which means they don't need special high-amperage circuits like many air conditioners do.
	The moist pads from an evaporative/swamp cooler are fairly efficient air filters, trapping some dust and pollen.
	A small evaporative cooler can be often placed in windows, much like a window air conditioner. Evaporative cooling requires simple installation from a reputable heating and cooling company.
	An evaporative cooler can cool outside air and blow it into your residential or commercial business re-circulating stale inside air.
	The evaporative cooler pads can be made of wood shavings - aspen trees is a popular choice.
