- Set realistic daily usage for hot days instead of assuming 24/7 operation.
- Replace the default electricity price with your actual utility rate to get a usable bill estimate.
How to reduce running cost
- Cool only occupied rooms and raise the thermostat a little when possible.
- Clean filters and keep doors and windows closed while the unit is running.
- Compare the cost of longer runtime against a better-insulated room or a more efficient unit.
