Frequently Asked Questions
Real answers to the most common portable vs split AC questions.
No. Portable ACs are significantly less effective than split ACs for several reasons: (1) The exhaust hose creates negative pressure, pulling hot outside air back into the room through gaps. (2) The compressor inside the room generates heat. (3) EER ratings of 2.5–3.2 vs ISEER 4.5–5.5 for split ACs means 30–50% more electricity for the same cooling. For rooms above 120 sq ft or daily use above 4 hours, a split AC is always the better choice.
