How many BTU in 1.5 hp air conditioner?

A 1.5 horsepower (hp) air conditioner typically has a cooling capacity of about 18,000 BTU (British Thermal Units) per hour. This is based on the general conversion where 1 hp is approximately equal to 12,000 BTU. Therefore, a 1.5 hp unit would be calculated as 1.5 x 12,000 BTU, resulting in around 18,000 BTU.
