It's also pretty easy to answer how many square feet a 3-ton air conditioner covers. If you apply the rule of thumb of 20 BTU per square foot, you'll see that a 3-ton air conditioner cools approximately 1,800 square feet of space. Overall, a 3-ton air conditioner can comfortably cool a 1500 square foot room. For an entire house, a 3-ton air conditioner is usually sufficient for a 2000 square foot detached house.
At the upper limit, a 3-ton air conditioner can cool a home with an area of up to 2400 square feet. Generally speaking, a 3-ton air conditioning unit is designed to cool approximately 3,000 square feet of space. However, depending on the factors mentioned above, this number may vary. Ultimately, to ensure the most accurate calculation of how many square feet a 3-ton air conditioner can cool, it's best to have the space and air conditioning unit evaluated by a professional.
