Air cooling is the most energy-efficient cooling technology available. Operating costs for an air cooler are 1/10th of a traditional air conditioner. A 2.2-ton split air conditioning unit can consume 2200 watts an hour. A Symphony air cooler consumes nearly the same amount of energy as a standard ceiling fan. Symphony air cooling units require energy in the range of 105 watts/hr to 255 watts/hr.Although the energy consumption of a ceiling fan and air cooler is similar, the cooling effect is considerably different. Air coolers can cover a larger area, actually cool the air, and work noiselessly.
