1. What is AC Size Calculation?

AC size calculation determines the appropriate air conditioning capacity needed for a room based on its area. Proper sizing ensures efficient cooling, energy savings, and optimal performance.

2. How Does the Calculator Work?

The calculator uses the AC size formula:

Where:

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

Explanation: The formula calculates the required cooling capacity by multiplying room area by 25 BTU per square foot, then converts the result from BTU to tons of cooling capacity.

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, comfort, and equipment longevity. An oversized unit cycles too frequently, while an undersized unit runs continuously without achieving desired temperature.

4. Using the Calculator

Tips: Enter the room area in square feet. The calculator will determine the recommended AC size in tons. Ensure accurate room measurements for best results.

5. Frequently Asked Questions (FAQ)

Q1: Why is 25 BTU per square foot used?
A: This is a standard factor for average residential rooms with normal ceiling height and insulation. It may vary based on specific conditions.

Q2: What if my room has special conditions?
A: For rooms with high ceilings, large windows, or poor insulation, you may need to adjust the BTU factor upward.

Q3: How do I measure room area accurately?
A: Multiply the length by width of the room. Include all areas that need cooling in your calculation.

Q4: What are common AC sizes available?
A: Common residential AC sizes range from 1 ton to 5 tons, with 1 ton cooling approximately 400-600 square feet.

Q5: Should I consider other factors besides area?
A: Yes, consider ceiling height, window size, insulation quality, number of occupants, and heat-generating appliances for precise sizing.
