What BTU needed for a 144 ft room?

To estimate the BTU (British Thermal Unit) needs for a 144 square foot room, a general guideline is to allocate about 20 BTUs per square foot for cooling and 30-40 BTUs per square foot for heating, depending on factors like insulation and climate. For cooling, this would result in approximately 2,880 BTUs. For heating, you might need between 4,320 to 5,760 BTUs. Always consider specific conditions such as ceiling height, number of Windows, and occupancy for a more accurate calculation.
