When it comes to choosing the right AC unit for your space, it's important to consider the size of the room. A 2 ton AC unit is typically suitable for a room size of around 150-300 square feet. However, this can vary depending on factors such as ceiling height, insulation, and the number of windows in the room. It's always best to consult with a professional HVAC technician to determine the appropriate size for your specific needs.
