1. What is AC Tonnage?

AC tonnage refers to the cooling capacity of an air conditioning system. One ton of cooling equals 12,000 BTU per hour. Proper sizing is crucial for efficiency and comfort in your home.

2. How Does the Calculator Work?

The calculator uses the standard formula:

Where:

• \( Area \) — Area to be cooled in square feet
• \( 20 \) — Standard BTU per square foot (adjustable for climate)
• \( 12000 \) — Conversion factor (BTU to tons)

Explanation: The formula calculates the required cooling capacity based on the area and standard cooling requirements.

3. Importance of Proper AC Sizing

Details: Correct AC sizing ensures energy efficiency, proper humidity control, and system longevity. Oversized units short cycle, while undersized units run constantly.

4. Using the Calculator

Tips: Enter the total area to be cooled in square feet. For more accurate results, consider factors like ceiling height, insulation, and climate.

5. Frequently Asked Questions (FAQ)

Q1: What if my home has high ceilings?
A: For ceilings over 8 feet, multiply the result by 1.25. For very high ceilings, consult an HVAC professional.

Q2: Does this work for commercial spaces?
A: Commercial spaces often have different requirements. This calculator is designed for residential use.

Q3: Should I round up the tonnage?
A: AC units come in standard sizes (1.5, 2, 2.5, 3, etc. tons). Round to the nearest standard size, but consult an HVAC professional.

Q4: What about very hot climates?
A: In extreme climates, you may need to adjust the BTU per square foot factor (from 20 to 25 or more).

Q5: Are there other factors to consider?
A: Yes - insulation quality, window size/direction, local climate, and heat-generating appliances all affect cooling needs.
