The cooling capacity of an AC is measured in tons. As a general guideline, a 1-ton AC is suitable for small rooms usually under 150sqft, while a 1.5-ton AC is recommended for larger spaces usually around 180sqft. Factors such as room size, insulation, number of occupants, and heat-generating appliances should be considered when determining the appropriate AC capacity for your specific needs.
