Ready to save money? Let’s get started.

Key Takeaways

  • Setting your air conditioner to 22-25 degrees Celsius saves up to 10% on energy costs.
  • Regular maintenance, like cleaning filters and checking coolant levels, helps reduce electricity use.
  • Switching to energy-efficient models with inverter technology can save you up to $303 a year.
  • Improving home insulation by closing windows and fixing leaks keeps cool air in, reducing power consumption.
  • Using programmable thermostats and timers smartly controls cooling, preventing unnecessary energy waste.

Optimal Temperature Settings

Set your aircon between 22 and 25 degrees Celsius. This range saves you up to 10% on energy costs. A tiny change, like setting the unit one degree warmer, can also cut costs by as much.

Never set it more than 8 to 10 degrees below the outside temperature for efficiency. This balance gives you comfort while saving electricity in Singapore’s climate, where room temperature might feel stuffy without air conditioning.

Regular Maintenance for Efficiency

Keeping your air conditioner in top shape cuts down on energy use. It makes sure your unit works well and uses less power.

  1. Clean the air filter every month. Dust blocks airflow, making your aircon work harder.
  2. Schedule a professional servicing twice a year. Experts from Billy Aircon will check parts and fix any issues.
  3. Check coolant levels regularly. Low amounts mean your aircon isn’t cooling efficiently.
  4. Keep the area around outdoor units clear. Plants or debris can reduce airflow and efficiency.
  5. Inspect seals around windows and doors to ensure cool air stays inside.
  6. Use a programmable thermostat to control temperature effectively when you’re not home.
  7. Clear dust from vents and registers to improve air flow in your room.
  8. Watch for ice buildup on coils; this signals it’s time for maintenance.
  9. Listen for odd sounds coming from the unit; they can indicate problems that need quick fixes.

This approach helps you save electricity and keep your cooling costs low, all while extending the life of your air conditioning system.

Using Energy-Efficient Aircon Models

Switching to energy-efficient aircon models, like those with inverter technology, will cut your power use. Models with a 5-tick rating save you up to $303 yearly compared to 2-tick ones.

This tech adjusts the speed of the compressor—the heart of your aircon—reducing electricity consumption significantly. You’ll enjoy cool air without high bills.

Inverter models work smarter, not harder, giving you perfect temperatures and using less power. They match your cooling needs precisely and avoid the waste conventional units cause.

Plus, pairing these with ceiling fans can boost savings by another $386 every year. So, it’s clear upgrading is a smart move for comfort and economy alike.



Enhancing Home Insulation

Closing your windows, blinds, or curtains helps keep hot air out. This means your air conditioner doesn’t have to work as hard. Our team at Billy Aircon has seen big savings from just this simple step.

Use white or light-coloured backings on your blinds and curtains. They reflect the sun’s heat away from your home. Tinted windows also make a difference by keeping rooms cooler.

Another tip is to check for leaks around doors and windows. Fixing these can stop cool air from escaping. Your air conditioner uses less energy as a result. We often suggest adding weather stripping or caulking around leaky areas to our clients in Singapore for better insulation at home, ensuring their cooling systems run more efficiently and helping them save on electricity bills.

Smart Usage of Aircon



Smart usage of your aircon can lead to significant savings on your electricity bill. Here are tried and tested tips to help you achieve this.

  1. Cool-only rooms in use. Shut doors and vents in empty areas to direct airflow where needed.
  2. Install a programmable thermostat for automatic temperature adjustment during different times of the day.
  3. Set timers on your aircon unit, turning it off an hour before you leave the house or sleep.
  4. Use ceiling or standing fans to circulate cool air more efficiently, reducing the need for continuous aircon use.
  5. Choose energy-efficient modes like ‘Eco’ or ‘Sleep’ for lower power consumption while maintaining comfort overnight.
  6. During cooler periods, switch off the air conditioner and open windows for natural ventilation, saving energy.
  7. Block sunlight with curtains or blinds during peak heat times to lessen indoor warming and aircon workload.
  8. Regularly clean filters and check for leaks to maintain optimal efficiency and reduce unnecessary energy wastage.
  9. Consider an upgrade to an energy-efficient wall air conditioner if your current model is old and consumes more power.
  10. Learn how to use inverter AC technology, which adjusts power based on room temperature — this is crucial for saving electricity in Singapore’s warm climate.

Adopting these strategies ensures your living space remains comfortable without incurring high costs from excessive air conditioning usage.

The Myth of Leaving Aircon On

Many people think it’s better to leave the air conditioner running all day. This is not true. Turning off your cooling system when you don’t need it saves more power and money. A programmable thermostat helps manage this efficiently, making sure your home stays comfortable while using less electricity.

Studies show that constantly leaving an aircon on uses more energy than turning it on only when needed. If you want to cut down on your electricity bill, turn off the cooling unit as you leave for work or during cooler parts of the day.

This simple change can lead to significant savings over time without sacrificing comfort in Singapore’s warm climate.

Considerations for Aircon and Babies

Set your aircon between 22 and 25 degrees Celsius to keep babies comfortable. This range is ideal for their well-being. Use timers on your air-conditioner to manage its run hours, ensuring a steady temperature throughout the day or night.

Keeping windows, blinds, or curtains closed blocks out heat and sunlight, maintaining a cooler environment for your baby. For an even better effect, opt for tinted windows and use white or light-colored backings on blinds and curtains.

These steps help create a calming space where your baby can rest without feeling too hot or cold.

Check the room’s temperature regularly with a thermometer to make sure it stays within the safe range for babies. Adjusting the thermostat accordingly keeps the room from getting too chilly or overly warm—both situations you want to avoid for little one’s comfort and health.

Simple actions like choosing energy-efficient air conditioning models also contribute by using less electricity while still providing the optimum cooling performance needed in homes with young children.

Conclusion: Maximizing Savings and Comfort

You can cut down on your air conditioning bill and still keep cool. Choose the right temperature, between 22 and 25 degrees Celsius, for savings up to 10%. Keep your cooling system shipshape with regular check-ups.

Opt for energy-saving models when it’s time for an upgrade. Make your home snug to stop warm air from sneaking in.

Use timers for smart control over cooling hours. Myths like leaving the aircon on all day don’t help; they push bills higher. For homes with babies, picking a cosy yet cool room temperature is key.
