What does one ton of cooling equal in BTUs?

  1. 6,000 BTUs

  2. 12,000 BTUs

  3. 18,000 BTUs

  4. 24,000 BTUs

The correct answer is: 12,000 BTUs

One ton of cooling is equivalent to 12,000 British Thermal Units (BTUs) per hour. This measurement is derived from the amount of energy needed to melt one ton of ice in a 24-hour period, which translates to the cooling capacity of an air conditioning system. Understanding this conversion is crucial for professionals in the HVAC industry and home inspectors, as it helps in assessing the cooling capacity of air conditioning units. Having knowledge of BTU ratings is also essential for matching HVAC systems to the size of a space needing climate control, thus ensuring efficiency and comfort in residential environments.
