If you live in a warm, dry area, you can save on energy bills and keep your home comfy through the cooling season by installing a swamp cooler.. These coolers are designed to be alternatives to central air conditioning and can help add humidity to the air in a small indoor space.

Unlike conventional air conditioners that consume huge amounts of energy recirculating air inside your home, swamp coolers use a simple evaporative process to achieve efficient and environmentally friendly cooling that adds fresh air and removes pollutants in a room.

How will a swamp cooler save you money?

Swamp coolers rely on a fan, cooling pad and water to achieve cooling. The process involves the pulling in of dry air into the unit, where it evaporates water in the cooling pad, thus getting cooled while also releasing humidity into the air. This differs from how conventional AC units achieve cooling--mainly by using an energy-heavy compressor that circulates refrigerant through ducts across the home to facilitate the cooling process.

With a swamp cooler, there is no compressor or toxic refrigerant, and instead only a small, energy efficient fan is needed to suck air into the unit. This enables these evaporative coolers to achieve a high level of energy efficiency, saving you money.

You may also be able to save money on installation costs, as portable swamp cooler designs can easily be mounted on a window or wall to cool a section of your home. There is often no need for the cooler to be connected to an intricate system of ducts--as is the case with conventional cooling--translating to huge savings.

Determining the size of cooler you need

Correctly sizing your swamp cooler will translate into more effective cooling and better air circulation in your home. These cooler designs use a different rating than other conventional units, typically based on how many cubic feet of air the cooler can circulate in a certain space per minute. This is called a CFM (cubic feet per minute) rating, and is determined by the size of your cooling space. Typically, a correctly sized cooler should be able to cycle and cool air about 20-40 times each hour.

To calculate the approximate CFM rating that is ideal for optimal cooling in a specific room, divide the cubic feet measurement of the space to be cooled by 2, and then purchase a swamp cooler with a similar or slightly higher rating.

A correctly sized, well maintained swamp cooler can offer you great savings in utility costs this summer, allowing you to cool specific rooms according to your daily needs. Contact a local air conditioning repair expert for more information.
