150 sq. ft. ≠ 150 sq. ft. when it comes to AC sizing.

Two rooms can have the same area but completely different cooling requirements.

Room A: 🌙 • Ground floor • Shaded • Small window • 2 people • Night usage

Room B: ☀️ • Top floor • West-facing window • Direct afternoon sun • 3–4 people • Afternoon usage

Same size. Very different heat load.

That's why choosing an AC based only on square footage can lead to the wrong capacity.

Before you buy, look at:

→ Sun exposure → Glass/window area → Ceiling height → Occupancy → Roof & wall exposure → Usage pattern

Don't just measure the room. Understand the heat load.

📌 Save this for your next AC purchase.
