1. What is the AC Tonnage Calculation?

The AC tonnage calculation estimates the cooling capacity needed for a space based on its square footage. One ton of cooling equals 12,000 BTU per hour.

2. How Does the Calculator Work?

The calculator uses the basic tonnage formula:

Where:

• \( Sq\,Ft \) — Total square footage of the space
• 600 — Standard conversion factor (1 ton per 600 sq ft)

Explanation: This provides a rough estimate of required AC capacity. Actual needs may vary based on climate, insulation, and other factors.

3. Importance of Proper AC Sizing

Details: Proper AC sizing is crucial for energy efficiency and comfort. Undersized units struggle to cool, while oversized units short-cycle, reducing efficiency and humidity control.

4. Using the Calculator

Tips: Enter total square footage of the space to be cooled. The calculator will estimate the required AC tonnage.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculation accurate for all homes?
A: This is a basic estimate. For precise sizing, consider insulation, climate, windows, and other factors.

Q2: What if my home is well insulated?
A: Well-insulated homes may require less tonnage (use 700-900 sq ft per ton instead of 600).

Q3: What about hot climates?
A: In very hot climates, you may need more capacity (400-500 sq ft per ton).

Q4: How important is proper AC sizing?
A: Critical - improper sizing can increase energy costs by 20-40% and reduce equipment life.

Q5: Should I round up the tonnage?
A: Generally round to nearest 0.5 ton, but consult an HVAC professional for specific recommendations.
