The split-system equipment schedule lists 72,000 Btu per hour of cooling capacity. What tonnage does that equal?

Correct Answer

A) 6 tons.

One ton of cooling equals 12,000 Btu per hour, so 72,000 divided by 12,000 equals 6 tons.

Answer Options
A
6 tons.
B
5 tons total.
C
6.5 tons total.
D
7 tons total.

Why This Is the Correct Answer

One ton of cooling equals 12,000 Btu per hour, so 72,000 divided by 12,000 equals 6 tons.

Why the Other Options Are Wrong

Option B: 5 tons total.

5 tons total. is below the supported result for hvac capacity conversion; it likely skips a premium-pay or employer-cost component.

Option C: 6.5 tons total.

6.5 tons total. is above the supported result for hvac capacity conversion; it likely pays the wrong premium tier or counts the same hours twice.

Option D: 7 tons total.

7 tons total. is above the supported result for hvac capacity conversion; it likely pays the wrong premium tier or counts the same hours twice.

Memory Technique

Who controlled ton, who paid cooling, where is the Checking Equipment record?

Reference Hint

Study anchor (closed-book): memorize HVAC capacity conversion from California Mechanical Code, California Code of Regulations Title 24. / Title 24 California Mechanical Code cooling capacity concepts; know the rule or calculation trigger without relying on exam-room lookup.
