If a home air conditioner is rated to remove 24,000 BTU's in 1 hour, what is its tonnage rating?

To determine the tonnage rating of an air conditioner, it's essential to know the relationship between BTUs and tons. One ton of cooling capacity is equivalent to 12,000 BTUs per hour.

Given that the air conditioner in question removes 24,000 BTUs in one hour, you would calculate the tonnage by dividing the BTU rating by the number of BTUs per ton:

24,000 BTUs ÷ 12,000 BTUs/ton = 2 tons.

Therefore, the air conditioner's tonnage rating is 2 tons, which is why it is the correct answer. Understanding this conversion is crucial for working in HVAC operations, as it helps in selecting the appropriate air conditioning units based on space requirements and cooling capacities.
