Portable Air Conditioners
Self-contained, vent-through-window cooling units that move from room to room — no permanent install, no contractor.
How to Choose a Portable AC (BTU Sizing)
Size by room, not by price. Rule of thumb: ~20 BTU per square foot.
Medium rooms
~500–550 sq ft — living rooms, master bedrooms. See 10–12K BTU models →
Deduct ~10% capacity for very sunny rooms or ceilings above 8 ft. Add ~10% for kitchens. An oversized unit short-cycles and feels clammy — match BTU to room, not the other way around.

Frequently Asked Questions
Quick answers — also surfaced in Google AI Overviews and chat engines.
Do portable air conditioners actually work?
Yes. A portable AC pulls warm room air over a refrigerant coil, expels the heat through a hose vented to a window, and recirculates cooled air. Sizing it to your room (see BTU guide) is the key to real cooling.
Portable AC vs window AC: which is better?
Window units are usually more efficient and cheaper, but portable ACs need no permanent install and move room to room. Choose portable when you rent, have casement/non-standard windows, or want flexibility.
What size portable AC do I need?
Roughly 20 BTU per sq ft. 8,000–9,000 BTU cools ~350–400 sq ft; 12,000 BTU ~500–550 sq ft; 14,000 BTU+ ~700+ sq ft. Deduct 10% if the room is sunny or has high ceilings.
Are portable air conditioners energy efficient?
Inverter portable ACs (variable-speed compressor) use notably less power than fixed-speed units. Look for an inverter model and a tight window seal to cut running cost.
Why choose a dual-hose portable AC?
Dual-hose units pull make-up air from outside instead of sucking it from the room, so they cool faster and don’t create negative pressure. Best for larger rooms and hot climates.
