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:

• \( Tons \) — Air conditioning capacity in tons
• \( BTU \) — British Thermal Units (cooling capacity)

Explanation: This conversion helps homeowners understand what size AC unit they need based on the BTU rating.

3. Importance of Proper AC Sizing

Details: Properly sized AC units operate more efficiently, last longer, and provide better humidity control. Oversized units cycle too frequently while undersized units run constantly.

4. Using the Calculator

Tips: Enter the BTU rating of your AC unit or the calculated BTU requirement for your space. The calculator will convert it to tons.

5. Frequently Asked Questions (FAQ)

Q1: How many square feet does 1 ton of cooling cover?
A: Approximately 400-600 sq ft per ton, depending on climate, insulation, and other factors.

Q2: What's the difference between BTU and tons?
A: They both measure cooling capacity - 1 ton = 12,000 BTU/hour. Tons are typically used for larger residential systems.

Q3: How do I calculate BTU requirements for my home?
A: Professional load calculations consider square footage, insulation, windows, climate, and more. Rule of thumb is 20 BTU per sq ft.

Q4: Can I use this for commercial AC units?
A: While the calculation works, commercial systems often have different requirements and should be professionally sized.

Q5: What happens if my AC is the wrong size?
A: Oversized ACs short cycle, reducing efficiency and dehumidification. Undersized ACs run constantly and can't keep up on hot days.
