What side or btu is need for a 1500 sft house?

The BTU (British Thermal Unit) requirement for a 1,500 square foot house typically ranges from 30,000 to 60,000 BTUs, depending on factors such as climate, insulation, and the number of Windows. A general rule of thumb is to use about 20 BTUs per square foot for heating and around 30 BTUs per square foot for cooling. However, it's best to conduct a detailed assessment or consult an HVAC professional to determine the specific needs of your home accurately.
