Air Conditioner Room Size Calculator
Calculate Room Size for AC Unit
About AC Room Size Calculation
This calculator determines the maximum room size that an AC unit can effectively cool based on its tonnage and environmental factors.
Formula:
Max Area = (Tonnage × 12,000) / (BTU per sq ft × Insulation Factor)
Factors Considered:
- AC unit tonnage (cooling capacity)
- Climate zone (affects BTU requirements)
- Insulation level (affects efficiency)
- Ceiling height (affects volume)
Typical Coverage:
• 1 ton: 400-600 sq ft
• 1.5 tons: 600-900 sq ft
• 2 tons: 900-1,200 sq ft
• 3 tons: 1,200-1,800 sq ft
Important Notes:
• Results are estimates
• Consider room layout and windows
• Factor in heat-generating appliances
• Professional assessment recommended
Proper sizing ensures efficient cooling and energy savings. An oversized unit cycles frequently, while an undersized unit struggles to maintain temperature.
