1 Ton Ductless Mini split air conditioners feature a 12000 BTU Capacity which is to cool or heat a total of 500 square feet. 12,000 BTU capacity is the average mini split size in the general range category. All the below 1 ton ductless systems come pre-charged with either R410 or R22 freon; all include a digital remote and installation kit but they differ in features, price, brand and efficiency ratings. 855-382-8110.
Most air conditioners have their capacity rated in British thermal units (Btu). A Btu is the amount of heat necessary to raise the temperature of 1 pound (0.45 kilograms) of water one degree Fahrenheit (0.56 degrees Celsius).One Btu equals 1,055 joules. In heating and cooling terms, one ton equals 12,000 Btu. A typical window air conditioner might be rated at 10,000 Btu.For comparison, a typical 2,000-square-foot (185.8 square meters) house might have a 5-ton (60,000-Btu) air conditioning system, implying that you might need perhaps 30 Btu per square foot.s an example, if a 10,000-Btu air conditioner consumes 1,200 watts, its EER is 8.3 (10,000 Btu/1,200 watts). Obviously, you would like the EER to be as high as possible, but normally a higher EER is accompanied by a higher price.
