• As a general rule, a 10,000 BTU unit can cool spaces up to 450 square feet, while a 14,000 BTU unit is suitable for up to 550 square feet.
• Opt for a unit with a slightly higher BTU rating than the recommended size to account for factors like insulation, layout, and weather conditions.

2. Do portable air conditioners require special installation in an attic?

Most portable air conditioners come with a window installation kit that allows for easy setup in an attic space. However, it’s important to ensure proper ventilation and follow the manufacturer’s instructions carefully to ensure optimal performance and safety.

3. How important is energy efficiency when choosing a portable AC for an attic?

Energy efficiency is crucial, especially for attic spaces, as they can be challenging to cool and may require the portable AC to run for extended periods.
