Our Verdict

Midea Duo MAP12S1TBL

LG DUAL Inverter LP1419IVSM

The Midea Duo MAP12S1TBL is simply better overall than the LG DUAL Inverter LP1419IVSM. The Midea's dual-hose design gives it a major advantage in efficiency over the LG, allowing it to cool a comparably sized room much faster while consuming less energy. Its two-in-one hose design also means that it's only marginally bulkier than the single-hose LG.
