How Much Does It Cost to Run an AC in Zanzibar?
Running cost depends on unit capacity and efficiency, hours of use, set temperature, room insulation and maintenance condition.
The main variables
Power draw multiplied by hours of use drives your bill. An oversized or poorly maintained unit consumes more for the same comfort, and every degree lower on the thermostat increases consumption.
Where the waste happens
Dirty filters and coils, open doors and windows, uninsulated roofs, direct sun on glass, and outdoor units starved of airflow all increase running time.
Reducing it
Service regularly, set a realistic temperature, use fans to improve perceived comfort, shade windows, and close rooms being cooled.
