1. What is AC Square Footage per Ton?

The AC Square Footage per Ton calculation helps determine the appropriate air conditioning capacity needed for a given space. One ton of cooling capacity typically covers about 600 square feet in a standard residential application.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( \text{Tons} \) — Cooling capacity in tons (1 ton = 12,000 BTU/hr)
• 600 — Standard square feet coverage per ton of cooling

Explanation: This provides a rough estimate of how much area a given AC unit can effectively cool under standard conditions.

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 struggle to maintain temperature.

4. Using the Calculator

Tips: Enter the cooling capacity in tons (common residential units range from 1.5 to 5 tons). The calculator will estimate the square footage that can be effectively cooled.

5. Frequently Asked Questions (FAQ)

Q1: Is 600 sq ft per ton always accurate?
A: No, this is a general rule of thumb. Actual needs vary based on climate, insulation, ceiling height, and other factors.

Q2: What if my space is larger than the calculation?
A: You may need additional cooling capacity or should consult an HVAC professional for a Manual J calculation.

Q3: How does climate affect this calculation?
A: Hotter climates may require more capacity (e.g., 500 sq ft/ton), while milder climates might get 700 sq ft/ton.

Q4: What about commercial spaces?
A: Commercial calculations are more complex and consider occupancy, equipment heat, and other factors.

Q5: Should I use this for a final AC purchase decision?
A: No, this is for estimation only. Always consult with an HVAC professional for proper system sizing.
