1. What is AC Tonnage Calculation?

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

2. How Does the Calculator Work?

The calculator uses the AC tonnage formula:

\[ T = \frac{(A \times 25)}{12000} \]

Where:

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

Explanation: The formula calculates the required cooling capacity in tons based on room area, using standard BTU requirements per square foot.

3. Importance of Proper AC Sizing

Details: Correct AC sizing is crucial for energy efficiency, proper humidity control, extended equipment life, and optimal comfort. Oversized units cycle frequently, while undersized units run continuously without adequate cooling.

4. Using the Calculator

Tips: Enter room area in square feet. Measure the length and width of the room and multiply them to get the area. Consider additional factors like ceiling height, insulation, and sun exposure for more accurate sizing.

5. Frequently Asked Questions (FAQ)

Q1: What is a "ton" in AC terminology?
A: One ton of cooling equals 12,000 BTU per hour, which represents the amount of heat needed to melt one ton of ice in 24 hours.

Q2: Is this calculation sufficient for all rooms?
A: This provides a basic estimate. For precise sizing, consider additional factors like ceiling height, window area, insulation quality, and local climate.

Q3: What if my room has high ceilings?
A: For ceilings higher than 8 feet, increase the calculated tonnage by 10-15% to account for the additional volume.

Q4: How does room orientation affect AC sizing?
A: South-facing rooms with more sun exposure may require 10-20% more cooling capacity than north-facing rooms.

Q5: Can I use this for multiple rooms?
A: This calculator is designed for single rooms. For whole-house calculations, sum the areas of all rooms and apply the formula, then consult with an HVAC professional.
