The most critical step is getting the right "tonnage" (cooling capacity). An undersized unit won't cool effectively, while an oversized one will cycle on and off too frequently, wasting energy. Ideal for rooms around 100–120 sq ft. 1.5 Ton: Best for medium spaces (150–185 sq ft). 2+ Tons: Required for large halls or open layouts.
Increase capacity by 10% if the room is very sunny or has high ceilings. 2. Choose the Right Type What to Consider When Buying an Air Conditioner - Daikin buy air conditioner online
