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 (British Thermal Units) per hour. This measurement helps determine the appropriate size of AC unit needed for a space.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Tons \) — Cooling capacity in tons
• \( BTU/h \) — British Thermal Units per hour

Explanation: This conversion helps translate BTU ratings (common on AC units) into tonnage (common for system sizing).

3. Importance of Proper AC Sizing

Details: Correct AC tonnage is crucial for energy efficiency and comfort. An undersized unit won't cool properly, while an oversized unit will short-cycle, reducing efficiency and lifespan.

4. Using the Calculator

Tips: Enter the BTU/h rating from your AC unit or the calculated cooling load for your space. The result shows the equivalent tonnage.

5. Frequently Asked Questions (FAQ)

Q1: What's the relationship between tons and BTU?
A: 1 ton of cooling = 12,000 BTU/hour. This originates from the amount of heat needed to melt 1 ton of ice in 24 hours.

Q2: What size AC do I need for my home?
A: Typically 1 ton per 400-600 sq ft, but this varies by climate, insulation, and other factors. A professional load calculation is recommended.

Q3: Can I convert tons to BTU?
A: Yes, simply multiply tons by 12,000 (e.g., 2 tons = 24,000 BTU/h).

Q4: Why is proper sizing important?
A: Proper sizing ensures efficient operation, adequate dehumidification, and prevents excessive wear on the system.

Q5: What are common residential AC sizes?
A: Common sizes range from 1.5 tons (18,000 BTU) to 5 tons (60,000 BTU) for most homes.
