Higher Electricity Bills: A single standard air conditioning unit can consume up to 1.2 kW per hour. Multiply that by 10–12 hours after school hours (including overnight), and you’re spending on electricity no one is actually using.
Increased Carbon Footprint: South Africa’s ongoing energy challenges mean wasteful electricity usage strains the grid further, contributing to loadshedding pressures.
Long-Term Equipment Wear & Tear: Leaving units running when not needed reduces the lifespan of the equipment, leading to higher maintenance costs down the line.
