1. What is Air Conditioner Unit Size?

Air conditioner unit size refers to the cooling capacity measured in tons, where 1 ton equals 12,000 BTU/h. Proper sizing is crucial for efficient cooling and energy savings.

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 (input value)
• 12000 — Conversion factor (1 ton = 12,000 BTU/h)

Explanation: This calculation converts BTU per hour rating to standard air conditioner tonnage.

3. Importance of Proper AC Sizing

Details: Correct sizing ensures energy efficiency, proper dehumidification, and system longevity. Oversized units short-cycle, while undersized units run constantly.

4. Using the Calculator

Tips: Enter the BTU/h rating from your air conditioner specifications or load calculation. The result shows the equivalent tonnage.

5. Frequently Asked Questions (FAQ)

Q1: How many BTU/h are in 1 ton?
A: 1 ton of cooling equals 12,000 BTU per hour.

Q2: What size AC do I need for my home?
A: Residential AC units typically range from 1.5 to 5 tons (18,000 to 60,000 BTU/h), but a Manual J calculation is needed for precise sizing.

Q3: Can I use this for heat pumps?
A: Yes, the same calculation applies to heat pump cooling capacity.

Q4: What's the relationship between SEER and tons?
A: SEER measures efficiency (BTU/h per watt), while tons measure capacity. They're related but different metrics.

Q5: Why is proper sizing important?
A: Proper sizing ensures optimal performance, energy efficiency, humidity control, and equipment lifespan.
