About evaporative cooler running costs
Evaporative (swamp) coolers use a fan and a small pump, so they cost a fraction of an air conditioner in dry climates.
Typical sizes: 100 W, 200 W, 300 W, 500 W.
How to spend less: Use it in dry weather only. In humid air it cools poorly.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Minnesota. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
