Swamp coolers, also known as evaporative coolers, operate by drawing hot air in from outside. The air comes through the cooler past a screen. The dry air picks up moisture. The swamp coolers system causes the water to evaporate from the air which cools it before it is blown into the home. Swamp coolers are an affordable method for cooling your home and are less drying to the indoor air than a standard air conditioner.

Cooler Size

The larger your home, the larger the swamp cooler needed and the more expensive it will be. To calculate the size that you need you can multiply the square footage of your home, times the height of your ceilings, times the amount of air exchanges needed per hour (typically 30). So for a 2,000 square foot home with 8 foot ceilings, you would need a swamp cooler that provides 480,000 cubic feet of air or 8,000 cubic feet per minute. This is the figure you look for when purchasing your swamp cooler.
You can save money by buying a smaller system, but if it doesn't cool your home effectively it may not be worth it. If there is just one room or area of your home you want cooled, you can buy a smaller unit and install it just in that one area as a way to save on costs

Installation Location

Where your cooler is installed will have a huge affect on the cost of installation. You can purchase swamp coolers that require no installation at all, merely plug into the outlet and are portable enough t place anywhere you want them. But for a whole house system, you may want to install your cooler on your roof with a duct that brings the cool air into your home. Other places that coolers are commonly installed are attics, and basements. In these cases, the amount of duct work needed, the steepness of your roof, or the accessibility of the space you need to place your swamp cooler will have a large affect on the cost of installation

Energy Costs

Swamp coolers run on electricity and so using one on a regular basis will raise your electric bills, however It is typically less expensive to run swamp cooler than a standard air conditioner. Swamp coolers do use large amounts of water, however, so if you live in an area with scarce or expensive water you may opt for a different type of system.

I would mention that a swamp cooler is much more effective if a person lives in a relatively dry climate. Although helpful, they do not perform as well in high humidity.

I'm a proofreader - it should be "will have an effect," not "affect". Example: The cost will affect me, because it will have an effect on me.
