How to Choose the Right AC: A Capacity & Efficiency Guide

An air conditioner with the wrong capacity will either fail to cool the room or run constantly and inflate your electricity bill. The right choice is the key to comfort and savings.

How is capacity (BTU) calculated?

Roughly, you need 600–700 BTU per square meter. For example, a 20 m² room needs about 12,000 BTU (1.5 HP). However, these factors increase the required capacity:

• Sunny rooms with large facades
• High ceilings
• Heat-generating areas like kitchens
• Spaces used by many people

Inverter or fixed-speed?

Inverter units adjust compressor speed, significantly reducing energy use and running more quietly. Although the initial investment is a bit higher, it pays for itself over time.

Why does placement matter?

Correct positioning of the indoor unit directly affects air distribution and efficiency. The outdoor unit should be mounted in a well-ventilated, serviceable spot.

The right capacity and proper installation are the two most important factors that determine your AC's lifespan and efficiency.
