How do I choose the right BLACK+DECKER portable air conditioner or heater for my room size?

To select the best BLACK+DECKER portable air conditioner or heater, consider the square footage of your space and the product’s BTU (British Thermal Unit) rating. In general, higher BTUs will provide more power and are ideal for larger spaces.  Lower BTUs will have comparatively less power and are suited for smaller spaces. Each product listing provides recommended room sizes and specifications to help you find the most effective heating or cooling solution for your needs.
