7 Ways to Cut Your Air Conditioning Running Costs
Simple, practical tips to keep your rooms cool without a scary electricity bill this summer.
Air conditioning doesn't have to break the bank. A few habits make a real difference to your bill:
- Set a sensible temperature — every degree lower costs more. 24°C is comfortable and economical.
- Use the timer and sleep modes so the unit isn't running when you don't need it.
- Close curtains and blinds during the day to keep solar heat out.
- Seal the window kit properly — gaps let warm air straight back in and make the unit work harder.
- Clean or replace filters monthly in summer; a clogged filter kills efficiency.
- Cool only the room you're in and keep its door closed.
- Choose an A-rated (or A++ for split systems) unit — the running-cost difference over a summer is significant.
