The term "1.5 ton" when referring to an air conditioner doesn't actually refer to its weight. Instead, it indicates the cooling capacity of the AC in tons. One ton of cooling capacity is equivalent to approximately 12,000 BTU (British Thermal Units) per hour.
To clarify, a 1.5-ton AC has a cooling capacity of approximately 18,000 BTU per hour (1.5 tons x 12,000 BTU/ton). This cooling capacity is a measure of how much heat the AC can remove from the air in an hour.
The weight of an air conditioner, including the copper components, can vary significantly based on the specific model and design. It depends on various factors such as the size, type of compressor, additional features, and the materials used in construction.
If you're interested in knowing the weight of a particular 1.5-ton AC unit, you should refer to the product specifications provided by the manufacturer. The weight is usually mentioned in the product's manual or on the packaging.
