How many feet does a 18000 btu air conditioner?

The cooling capacity of an air conditioner, measured in BTUs (British Thermal Units), does not directly correlate to a specific number of feet. However, a general rule of thumb is that an 18,000 BTU air conditioner can effectively cool a space of around 800 to 1,000 square feet, depending on factors like insulation, ceiling height, and climate. It's important to consider these variables for optimal cooling efficiency.
