How to Boost Energy Savings with Proper AC Use

Maximising energy savings with your air conditioning system can be as simple as implementing strategic usage practices. Discover how fine-tuning daily habits and understanding the nuances of AC operation can lead to a more efficient and cost-effective indoor climate.

Proper regulation of AC temperature

Set your air conditioner to a comfortable yet energy-saving temperature. Keep it around 25-26 degrees Celsius for efficiency. Each degree above this can save about 3% on cooling costs.

Prevent setting the AC too cold in a rush to cool down; this uses more energy. Instead, lower the temperature gradually.

Use curtains or blinds during hot days to block out sunlight and keep rooms cooler naturally. This helps maintain a stable indoor climate without overworking your AC unit. A steady, moderate setting works best rather than constant adjustments that spike energy use.

Keep doors and windows shut while the AC is running to lock in cooled air.

Programming the air conditioner for energy saving

Properly regulating your AC temperature is key to saving energy. Now, let’s look at how programming your air conditioner can further enhance energy savings.

  • Use a programmable thermostat: This device lets you set temperatures for different times of the day. You can programme it to cool your home before you arrive and turn off when you leave.
  • Aim for gradual changes: Adjusting the temperature slowly helps to save power. Avoid sharp drops in temperature that cause high energy usage.
  • Plan around peak hours: Programme your AC to run less during times when electricity rates are highest, usually in the afternoon.
  • Factor in humidity levels: Since high humidity can make it feel hotter, use a smart thermostat that also controls a dehumidifier.
  • Match settings with outdoor temps: Keep indoor temperatures closer to outside conditions to reduce strain on your AC unit.
  • Utilise sleep mode at night: Many modern air conditioners have a sleep mode which raises the temperature gradually while you’re asleep to use less energy.
  • Consider occupancy sensors: Some thermostats have sensors that detect if a room is empty and adjust the AC accordingly.
  • Check for seasonal adjustments: Update your thermostat’s settings as seasons change to ensure optimal performance and energy savings.

Factors Influencing AC Energy Saving

Several elements significantly impact the energy-saving potential of your air conditioning system, beyond mere usage patterns. Understanding these factors is key to optimising efficiency and reducing overall climate control expenses in your home or office environment.

Effect of humidity on AC energy efficiency

High humidity makes air conditioners work harder. This means they use more energy to cool your home. Malaysia’s climate is often hot and humid, pushing AC systems to their limits. Air conditioners remove moisture from the air as part of the cooling process.

More humidity results in more work for the AC unit.

Your air conditioner has to run longer and stronger on humid days to reach the desired temperature. This extra effort increases your electricity bill significantly. Keep indoor humidity low by using dehumidifiers or exhaust fans, especially during high-humidity periods like monsoon season in Pahang.

Proper insulation also stops moist outside air from coming in, easing the burden on your AC system.

Furniture layout and AC airflow

Arrange your furniture to let air flow freely around the room. Keep sofas, chairs, and tables away from your AC unit’s path. This helps cool air spread evenly throughout the space.

Make sure wall-mounted air conditioners are not blocked by high shelves or curtains. Proper installation is key for these units to work well.

Keep heat-producing devices like lamps and TVs away from your thermostat. This stops them from making the air conditioner think it’s hotter than it really is. Next, we’ll look at managing other appliances for better AC efficiency.

Managing heat-generating appliances for improved AC efficiency

Heat-generating appliances can make your air conditioner work harder. Keep them away from your AC to save energy.

  • Use appliances that create heat, like ovens and cookers, less often during hot days.
  • Run your dishwasher, washing machine, and dryer at night when it’s cooler.
  • Plug in TVs, computers, and other electronics away from the air conditioning unit.
  • Turn off lamps and switch to LED lights as they produce less heat.
  • Keep the fridge door closed as much as possible to avoid warm air entering and making it work harder.
  • Cover pots while cooking to keep the kitchen cooler and reduce cooker use time.
  • Air – dry dishes instead of using the heat dry setting on your dishwasher to cut down on heat.
  • Take shorter showers with cooler water to minimise humidity and heat in your home.
  • Open windows for natural ventilation when it’s cool outside to reduce AC use.
  • Maintain your appliances by cleaning filters regularly and servicing them for optimal performance.

Importance of shading and insulation in reducing AC workload

Shading your windows can keep your home cooler. It stops the sun’s rays from heating up rooms. This means your air conditioner doesn’t have to work as hard. Trees, curtains, and window films are good for shading.

Insulation is just as important for a cool house. It keeps warm air out and cool air in during summer. Your home stays comfortable without making the AC unit work overtime. Proper insulation saves energy and lowers cooling costs too.


Keep your air conditioner running efficiently with these simple steps. Clean filters and regular maintenance save power and costs. Choose the right size and energy-efficient model for your home.

Use shades, blinds, and smart temperature settings to stay cool while conserving energy. Enjoy a comfortable indoor environment without wasting electricity by applying these tips for effective air conditioning use.
