How to calculate hvac tons
This calculator converts a BTU/hour cooling load into tons of refrigeration — the standard capacity unit for air conditioning and heat pump equipment.
How the calculation works
Tons = BTU per hour ÷ 12,000. One ton of refrigeration is defined as 12,000 BTU/hour of cooling capacity.
Example
A 30,000 BTU/hr cooling load: Tons = 30,000 ÷ 12,000 = 2.5 tons.

Pro Tips for HVAC Tons
- Residential AC equipment is commonly sized in standard increments (1.5, 2, 2.5, 3 tons, etc.) — round to the nearest standard equipment size.
- This conversion is a fixed, exact industry-standard definition and doesn't vary by equipment brand or type.
Common HVAC Tons Mistakes to Avoid
- Confusing tons of cooling capacity with tons of physical weight — they're unrelated units that share a name by historical convention.
