Frequently Asked Questions

What size portable air conditioner do I need?
Match BTU to room size. Roughly 20 BTU per sq ft for cooling. A 150 sq ft room needs about 6,000 BTU; 250 sq ft needs 8,000 BTU; 400 sq ft needs 12,000 BTU; 500 sq ft needs 14,000 BTU. In hot climates or for rooms with lots of sun, add 10-20% capacity. Oversizing wastes energy and can leave the room humid (ACs need to run longer to dehumidify). Undersizing won't cool effectively. Our top pick, the Midea Duo, has 14,000 BTU for up to 450 sq ft.
What's the difference between single-hose and dual-hose portable ACs?
Single-hose units use one hose to exhaust hot air—but that creates negative pressure, pulling warm air from outside through cracks and under doors, reducing efficiency. Dual-hose units have one hose for intake and one for exhaust, so they don't create negative pressure and cool more efficiently. Dual-hose models like the Midea Duo and Whynter ARC-14S perform better, especially in hot climates. Single-hose is cheaper and sufficient for small, well-sealed rooms.
Are portable air conditioners good for apartments?
Yes. Portable ACs are ideal for renters because they require no permanent installation—just a window kit that fits in a sliding or casement window. No landlord approval needed in most cases. They're flexible: move them between rooms, take them when you relocate. The downside is they're less efficient than window units and take floor space. For apartments where window units aren't allowed or practical, portables are the best option. Match BTU to your room size; 8,000-10,000 BTU works for most bedrooms.
