Compare energy efficiency and costs between portable AC fans and traditional air conditioning systems
Set your AC to 78°F (26°C) for optimal efficiency. Each degree lower increases energy consumption by 6-8%.
Proper insulation can reduce cooling costs by 20-30%. Seal windows, doors, and use thermal curtains.
Use programmable thermostats to automatically adjust temperature when you're away or sleeping.
Use ceiling fans, open windows at night, and plant shade trees to reduce AC dependency.
