Arizona is notorious for its almost year-round hot temperatures. Typically, the temperatures don’t dip below the 70s until at least December. That’s why staying cool is such a top priority. Many homeowners rely on their air conditioner to keep their home comfortable, but they might not realize there is a better option out there: the evaporative cooler.

An evaporative cooler, also known as a swamp cooler, often gets overlooked because residents don’t fully understands the benefits it has to offer in the dry desert environment. In actuality, evaporative coolers in Phoenix, AZ tend to be more cost effective and energy efficient when compared to a traditional AC. To help you fully understand the benefits, check out this brief guide on what evaporative cooling is and how it works.

What is evaporative cooling?

Evaporative cooling is a relatively simple way to maintain a cool temperature within a space. In fact, for many centuries, people from throughout the world have been incorporating the techniques used in evaporative cooling. Ancient Egyptians and early residents of the American Southwest would hang wet blankets across the doors and windows. As the hot, dry air passed over the water, the air began to cool off. Modern day evaporative coolers utilize this same principle—just in a much more efficient way. Swamp coolers are best used in hot, dry climates, which is why Phoenix is the perfect environment for this type of cooling device.

How does it work?

The evaporative cooler system is pretty simple. In most units, a pump circulates water from the reservoir and onto a cooling pad on the backside of the machine, which then becomes very wet. The fan then draws the outside warm air into the unit through the moistened pad. The air is then cooled through evaporation as it passes over the pad. The fresh, cool air is then blown out into the room. The lower the amount of humidity, the better the swamp cooler will be able to work.

What makes it better than a traditional AC unit?

Evaporative coolers are superior to traditional air conditioners on a variety of points:

  • Operational costs: Swamp coolers are more economical. Not only do they cost less to operate, but maintenance costs are also significantly lower. Plus, they don’t require much more than an annual maintenance check to function great all year long. You can also expect to see your energy usage drop exponentially after switching to a swamp cooler.
  • Air quality: Air quality is always a concern with an air conditioner. They work best in enclosed areas with the windows and doors shut. The same stale air is just re-circulated. Evaporative coolers, meanwhile, thrive on fresh air. It circulates outside air throughout your home, so you’ll have the peace of mind that comes with knowing your breathing in air that isn’t stale.
