Requirement Calculator (Finding the Power)

Before choosing a brand, you must determine the Horsepower (HP) or BTU needed based on the building type.

Building Type	Base Calculation (sq. ft.)	Factors to Add
Residential	Area x 70 BTU	+10% for high ceilings or large windows.
Shop House	Area x 80 BTU	+2,000 BTU for kitchens or high human traffic.
Church / Hall	Area x 100 BTU	+500 BTU per person at max occupancy.

Quick Reference (Horsepower to BTU)

• 1.0 HP: ~9,000 – 10,000 BTU (Small bedroom/office)
• 1.5 HP: ~12,000 – 13,000 BTU (Master bedroom/Small shop)
• 2.0 HP: ~18,000 BTU (Living room/Medium shop)
• 2.5 HP – 3.0 HP: ~24,000 – 30,000 BTU (Large hall/Restaurant)

2. Unit Cost & Brand Tiers (2026 Estimates)

Brand Tier	Example Brands	Price Range (1.0 HP)	Price Range (2.0 HP)
Premium	Daikin, Panasonic, Mitsubishi	1,800 – 2,500	3,200 – 4,500
Mid-Range	Samsung, LG, Haier	1,400 – 2,000	2,800 – 3,800
Budget	Midea, Gree, Hisense	950 – 1,500	2,000 – 3,000

Here is a comprehensive framework and data set you can use to build your calculator or manual quotation.
