1. Mind Your Temperature Setting

Set your AC so that its indoor temperature is about 8 °C cooler than outside (rather than making a huge drop). CHOICE

Each degree you drop below this margin can raise power use by about 10%. CHOICE

Aim for a balance between comfort and efficienc

2. Clean & Maintain Regularly

A clogged filter or dusty coil makes the AC work harder.

Routine servicing ensures efficiency and helps catch small faults early.

3. Use “Eco” or Smart Modes / Programmable Controls

Many modern units have eco, energy saver, or smart modes that adjust fan speed and compressor power to save electricity.

You can also use programmable or smart thermostats to cool only when needed (for example, pre-cool a little before you return home).

4. Zone Wisely & Seal Your Home

Only cool rooms you actually use, close doors to unused areas.

Also, seal leaks around windows, doors, and ducts to prevent cool air escaping. A well-insulated home helps your AC work less.

5. Use Fans & Shades to Assist Cooling

Use ceiling fans or standing fans to circulate air, you can comfortably set AC temperature a little higher when air is moving.

Keep curtains, blinds, or awnings closed during the hottest parts of the day to block direct sunlight.

6. Replace Old or Inefficient Units

If your AC is old or constantly breaking down, it may be more expensive to run than to replace.

Look for units with high efficiency ratings (SEER/EER / ENERGY STAR or local equivalent) and check real running cost data (not just marketing claims).
