6 Tips to Stay Cool Without Breaking the Bank

Summer is here, and while those long, sunny days are something to celebrate, staying cool without overworking your air conditioner (or your wallet) can be challenging. Here are six easy tips to maximise air conditioning efficiency and keep your home cool all summer.

1. Don’t Set the Temperature Too Low— It Won’t Cool Faster!

Setting your air conditioner to a super low temperature doesn’t cool your room faster. Instead, it forces the system to work harder, consuming more energy and increasing running costs. Air conditioners cool at a steady rate, so the target temperature only determines how long the unit will run—not the speed of cooling.

Finding the right balance is crucial. Every degree lower can significantly increase energy use. For example, lowering the temperature by 1°C can raise energy consumption by up to 10%, while adjusting it by 2°C can improve efficiency by as much as 20% without compromising comfort. Set your air conditioner to a reasonable, consistent level to stay cool efficiently without overworking your system.

2. Use Fan Mode on Mild Days to Cut Costs

Switching to fan-only mode on mild days saves energy by circulating air instead of running full cooling. Fans create a breeze that cools effectively with less power consumption. Likewise, using Cooling Mode instead of Auto Mode is more efficient since Auto Mode can toggle between heating and cooling, potentially running when it isn’t needed.

3. Block Out Heat to Help Your Air Conditioner Work Smarter

Closing curtains or blinds during peak sun hours prevents your home from heating up. Less sunlight entering your space means your air conditioner has less work to do to maintain a comfortable temperature. This simple action reduces heat gain and lowers your cooling costs.

4. Cool Targeted Areas to Avoid Waste

Focusing cooling efforts on the rooms you use most saves energy and keeps you comfortable where it matters. Shutting doors to unused spaces prevents cool air from escaping into areas that don’t need it. An OmniCore Multi Room System gives you individual control of each unit, so you can cool the kids' bedrooms before bedtime or switch off the living room unit when heading out. Adjust temperatures to suit and save energy by only cooling where and when you need it.

5. Regular Maintenance Boosts Efficiency

Keeping your air conditioner in top shape ensures it runs efficiently. Dirty filters or blocked vents force the system to work harder, using more energy and wearing out faster. Regularly cleaning or replacing filters and clearing debris ensures optimal performance and saves on energy costs.

That is why the EcoCore AP Series features our unique Dual Barrier Coating, keeping key internal components cleaner to maximise energy efficient performance and minimise internal odour build-up.

6. Track Energy Use and Tailor Comfort with Mitsubishi Electric Wi-Fi Control

Take full control of your air conditioning system with Mitsubishi Electric’s Wi-Fi Control. Through the App, set timers and temperature rules to ensure a room starts or stops cooling when you need it. With the new Wi-Fi Heat Pump Control Energy Monitoring feature, you can track your compatible high wall heat pump’s energy usage directly from your smartphone.

Heating and cooling are among the biggest contributors to your power bill, so knowing how much energy your air conditioner uses can help you make small changes to improve energy efficiency and save money. With Mitsubishi Electric Wi-Fi Control, the decision-making is in your hands, helping you stay cool and efficient.

Following these simple tips, you can enjoy a cool, comfortable home this summer without breaking the bank.
