It's easy to understand how many square feet a 3-ton air conditioner can cool. According to the rule of thumb of 20 BTU per square foot, a 3-ton air conditioner can cool approximately 1,800 square feet of space. Generally, this type of air conditioner is suitable for a 1500 square foot room. For an entire house, it can comfortably cool a 2000 square foot detached house.
At the upper limit, it can cool a home with an area of up to 2400 square feet. In general, a 3-ton air conditioning unit is designed to cool around 3,000 square feet of space. However, this number may vary depending on several factors. As an HVAC expert with more than 7 years of experience in design, installation, service and maintenance, I can tell you that understanding the basic concepts of HVAC is essential for getting the most accurate calculation of how many square feet a 3-ton air conditioner can cool.
