Energy-saving Tips - Are Inverter ACs Always the Most Energy-efficient? It’s All about Finding the Right Fit

During scorching summer months when air conditioners (AC) are running constantly, having an energy-efficient unit is crucial. While many people know inverter ACs are more energy-efficient than fixed-frequency models, what other factors should you consider when selecting an energy-saving air conditioner?

Horsepower (HP)

First, choosing the right horsepower is essential. The higher the HP rating, the greater the cooling capacity. Before selecting an AC unit, consider not just the room size but also your home's actual environmental factors. For example, an 80–100 sq. ft. room typically requires a 1HP unit. But if the room faces west and gets afternoon sun, you'll need one with slightly higher HP.

If you are opting for an inverter unit, avoid undersized units. If the HP is insufficient, the compressor will run continuously to maintain the set temperature, wasting energy instead of saving it.

Energy Efficiency Label Rating

According to EMSD data, a Grade 1 energy-labelled air conditioner saves about 23% more electricity than a Grade 3 model and 43% more than a Grade 5 unit.

Next time you shop for an air conditioner, compare your actual needs, pricing, and its energy efficiency to find the best fit!
