1. What is AC Tonnage Calculation?

AC tonnage calculation determines the cooling capacity needed for a space based on its square footage. One ton of cooling equals 12,000 BTU per hour, which can cool approximately 600 square feet of space.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Tons \) — Required air conditioning capacity
• \( Area \) — Total area to be cooled in square feet
• 600 — Standard square feet cooled per ton of AC

Explanation: This basic calculation assumes standard conditions (8-foot ceilings, average insulation, moderate climate).

3. Importance of Proper AC Sizing

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

4. Using the Calculator

Tips: Enter the total area to be cooled in square feet. For more precise calculations, consider factors like ceiling height, insulation, climate, and window exposure.

5. Frequently Asked Questions (FAQ)

Q1: What if my ceilings are higher than 8 feet?
A: Increase capacity by about 10% for each additional foot of ceiling height.

Q2: Does this work for commercial spaces?
A: Commercial spaces often require more precise Manual J calculations due to higher heat loads.

Q3: What about very sunny rooms?
A: South-facing rooms may need 10-20% more capacity, while north-facing rooms may need less.

Q4: How accurate is this simple calculation?
A: It provides a rough estimate. For exact sizing, consult an HVAC professional who can perform a Manual J calculation.

Q5: What if I have poor insulation?
A: Poor insulation may require 20-30% more cooling capacity to compensate for heat gain.
