1. What is an AC Tonnage Calculator?

Definition: This calculator converts cooling capacity in BTU/hr to air conditioning tonnage.

Purpose: It helps HVAC professionals and homeowners determine the appropriate AC unit size for a space.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — AC tonnage (tons)
• \( BTU \) — Cooling capacity (BTU per hour)

Explanation: One ton of cooling equals 12,000 BTU per hour. The formula converts BTU/hr to standard AC tonnage units.

3. Importance of AC Tonnage Calculation

Details: Proper tonnage calculation ensures efficient cooling, energy savings, and prevents overworking your AC system.

4. Using the Calculator

Tips: Enter the cooling capacity in BTU/hr (found on your AC unit specifications or calculated from room size).

5. Frequently Asked Questions (FAQ)

Q1: Why 12,000 BTU equals 1 ton?
A: This originates from the amount of heat needed to melt one ton of ice in 24 hours (288,000 BTU/24 hr = 12,000 BTU/hr).

Q2: What's a typical BTU requirement for a room?
A: Roughly 20 BTU per sq ft, but this varies based on insulation, climate, and other factors.

Q3: How many square feet will 1 ton cool?
A: Approximately 400-600 sq ft in moderate climates, but professional load calculations are recommended.

Q4: What if my calculated tonnage is between standard sizes?
A: Round up to the nearest half-ton (e.g., 2.3 tons → 2.5 ton unit).

Q5: Does this account for humidity control?
A: No, humid climates may require adjustments - consult an HVAC professional.
