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 capacity typically covers 500-600 square feet, with 3.5 tons covering approximately 2,100 square feet.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Tonnage \) — Air conditioner capacity in tons
• \( Square\;Feet\;per\;Ton \) — Typically 500-600 sq ft per ton (600 is standard for moderate climates)

Explanation: The calculation provides a rough estimate of the area that can be cooled by an AC unit of a given tonnage.

3. Importance of Proper AC Sizing

Details: Proper AC sizing is crucial for energy efficiency and comfort. An oversized unit will short cycle, reducing efficiency and failing to properly dehumidify. An undersized unit will run constantly and struggle to cool the space.

4. Using the Calculator

Tips: Enter the AC tonnage (typically 1-5 tons for residential units) and the square feet per ton (standard is 600 for moderate climates, adjust up for hotter climates or down for cooler ones).

5. Frequently Asked Questions (FAQ)

Q1: What size AC do I need for 2,000 sq ft?
A: Approximately 3.5 tons (2000 ÷ 600 = 3.33, rounded up to nearest standard size).

Q2: Can I use this for commercial spaces?
A: This is primarily for residential use. Commercial spaces have different requirements due to higher ceilings and occupancy.

Q3: What factors affect the square feet per ton?
A: Climate, insulation, ceiling height, window area, and sun exposure all affect the calculation.

Q4: Is 3.5 ton AC standard?
A: 3.5 ton is a common size for medium to large homes (2,000-2,500 sq ft in moderate climates).

Q5: Should I get a Manual J calculation?
A: For precise sizing, a Manual J load calculation by an HVAC professional is recommended, especially for new construction or major renovations.
