The design flaw making most portable air conditioners inefficient — and the simple fix
By
Michael Le Page
Summary
This article exposes a serious design flaw in many portable air conditioners: they are single-hose units that create negative pressure, sucking hot air into the room and making them highly inefficient. The author argues that dual-hose portable air conditioners are far more effective and that single-hose models should be banned or at least properly labeled. The piece calls for regulatory changes to require dual-hose designs and better efficiency labeling, noting that current efficiency ratings (like EER and SACC) mislead consumers about real-world performance.
