Choosing the best aircon

When choosing an aircon, you should consider these 9 points. The first 3 will go a long way in reducing your electricity bills.

  1. Cooling capacity: Air conditioner cooling capacity is measured in British Thermal Units (BTUs). The right BTU rating— not too high or too low— cools well without excessive energy costs.
  • First, calculate the square footage of the room and multiply by 65.
  • For a shaded room, decrease that number by 10%.
  • For a sunny room, increase it by 10%.
  • Add 4,000 BTUs for a kitchen A/C.
  • Add 600 BTUs per person if more than 2 people will be in the room regularly.
  1. Energy Efficiency Ratio (EER): EER stands for Energy Efficiency Ratio and a higher rating indicates better energy efficiency. A 1-point increase in EER cuts about 10% off your electricity bill. However, models with higher EER are more expensive.
  2. Inverter: Inverter air conditioners regulate compressor speed for precise temperature control and better energy efficiency.
  3. Air Quality: Some air conditioners come with additional features to improve indoor air quality, such as air purifiers, dehumidifiers and filters.
  4. Noise levels: Noise can be a factor for air conditioners in bedrooms or studies. A lower decibel rating means quieter operation.
  5. Features & controls: Programmable timers, adjustable fan speed, sleep modes, and Wi-Fi connectivity help you maintain a cool home without crazy energy bills.
  6. Installation & maintenance: Both installation and maintenance can be expensive. Look for installation-included packages and find out servicing costs for your brand and model.
  7. Brand & warranty: Some air conditioner brands are better for reliability and longevity. A comprehensive, long-term warranty is important.
  8. Budget: A reliable brand and model with high EER and energy-saving features may be more expensive to buy but will make up for it in long-term energy and maintenance costs.
