What is BTU and how is it different from HP?
BTU (British Thermal Unit) measures how much heat an air conditioner can remove from a room per hour - the higher the BTU, the more cooling power. In Malaysia, aircond is usually sold in HP (horsepower). The two are directly related: 1 HP is about 9,000 BTU. Choosing the correct size matters - an undersized unit runs non-stop and never cools, while an oversized unit cools too fast, leaves the room damp, and wastes electricity.
