Frequently Asked Questions

Common questions about BTU to Tons, formulas, and typical use cases.

How many BTU/h are in one cooling ton?

One refrigeration ton equals 12,000 BTU/h of cooling capacity.

Why are HVAC systems rated in tons?

Tons are a traditional HVAC capacity unit tied to refrigeration load, while BTU/h gives the same capacity in heat-rate terms.

Can I convert tons back to BTU/h?

Yes. Multiply tons by 12,000 to get BTU/h.

Does tonnage alone define full system performance?

No. Efficiency, airflow, static pressure, climate, and load profile all affect real system performance.
