About ductless mini split running costs
Mini-split power varies widely with capacity, efficiency and outdoor conditions. Rated input watts or the energy label gives a better estimate than cooling BTUs alone.
Typical sizes: 700 W, 1,000 W, 1,500 W, 2,500 W.
How to spend less: Clean indoor filters and set a steady temperature instead of frequent large changes.
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 Washington. 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.
