A BTU is a traditional unit of heat measurement defined as the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. In the HVAC world, BTU ratings are used to describe the cooling or heating capacity of a unit, with 12,000 BTUs being equal to one "ton" of refrigeration. When selecting Mobile Home Air Conditioners, it is vital to perform a "Manual J" load calculation to determine exactly how many BTUs your home requires. An undersized unit will run constantly without cooling the home, while an oversized unit will short-cycle and fail to remove humidity. Our ACIq product lines range from 9,000 BTU mini-splits to massive 60,000 BTU (5-ton) Packaged Units. Understanding BTU requirements helps you compare different systems and choose the most cost-effective solution for your square footage. It is the universal language of HVAC sizing and performance across all residential and commercial brands.
