1. What is the AC Size Calculator?

The AC Size Calculator determines the appropriate air conditioning capacity in tons for a room based on its area. Proper sizing ensures efficient cooling and energy consumption.

2. How Does the Calculator Work?

The calculator uses the AC sizing formula:

Where:

• \( T \) — AC size in tons
• \( A \) — Room area in square feet
• 25 — BTU per square foot factor
• 12000 — BTU per ton conversion factor

Explanation: The formula calculates the required cooling capacity based on room area, using standard BTU requirements and converting to tons.

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, proper cooling performance, and preventing premature system failure. Oversized units cycle too frequently, while undersized units run continuously.

4. Using the Calculator

Tips: Enter the room area in square feet. The calculator will determine the recommended AC size in tons. Consider additional factors like ceiling height, insulation, and sun exposure for precise sizing.

5. Frequently Asked Questions (FAQ)

Q1: Why is proper AC sizing important?
A: Proper sizing ensures efficient operation, adequate cooling, lower energy bills, and longer equipment lifespan.

Q2: What factors affect AC sizing besides area?
A: Ceiling height, insulation quality, window size/direction, number of occupants, and heat-generating appliances.

Q3: What is the standard BTU per square foot?
A: Typically 20-25 BTU per square foot for standard rooms, but this can vary based on climate and room characteristics.

Q4: How many square feet does 1 ton AC cool?
A: Approximately 400-600 square feet, depending on various factors like insulation and climate conditions.

Q5: Should I round up or down when choosing AC size?
A: It's generally better to round up slightly for better performance, but avoid significant oversizing which can cause humidity problems.
