A/C Size Calculator
Calculate the perfect air conditioner size for your room based on room dimensions, insulation, climate, and other factors. Determine the right BTU (British Thermal Units) for optimal cooling efficiency.
Step 1: Room Specifications
Understanding BTU Requirements
BTU (British Thermal Units) measures cooling capacity. A properly sized A/C unit cools efficiently without wasting energy. Undersized units run constantly, while oversized units cycle too quickly.
Step 2: Climate & Conditions
About A/C Sizing Factors
Proper A/C sizing considers room volume, insulation, climate, sun exposure, and occupancy. Undersized units struggle to cool, while oversized units create humidity problems and waste energy.

BTU Calculation Breakdown
BTU Calculation Formula
BTU = Base BTU × Climate Factor × Insulation Factor × Sun Factor × Occupancy Factor
Base BTU is calculated from room area (20 BTU per sq ft). Each factor adjusts the BTU requirement based on specific room conditions and climate.
