Portable Air Conditioners: Everything You Need to Know

Portable ACs offer flexibility no other type can match. Roll them from room to room.

How Portable ACs Work

Entire system in one freestanding cabinet. Exhausts through window hose.

Single-Hose vs Dual-Hose

Simpler, cheaper, but creates negative pressure. 30-40% less efficient.

Separate intake and exhaust hoses. No negative pressure. Significantly more efficient.

Understanding BTU Ratings

DOE SACC rating is the real measure. 8,000 BTU DOE = ~14,000 BTU ASHRAE.

When a Portable AC Makes Sense

  • Renting — can't install permanent AC
  • Incompatible windows
  • Need cooling in different rooms
  • Temporary solution
  • Building prohibits exterior units

Maintenance Tips

Handle condensation. Clean filter every 2 weeks.
