An evaporative cooler consumes only about a quarter of the electricity required to run an air conditioner, but it uses enough water over the summer to fill a swimming pool. That’s all lost water because it quickly evaporates into the air. In our desert climate, that’s not an efficient choice.
Today’s super-efficient air conditioners generally trump evap coolers in the efficiency department. If you’re running an evap cooler along with your a/c, they’re competing with each other as the a/c removes humidity from the air and the evap cooler adds it back in. That’s just a waste of money.
Your best bet: Reserve your evap cooler for spot cooling, like in the garage or on your back patio. For all your other cooling needs, stick with the a/c.
