This spring I ran four smart window units through lab drills and real-home living: LG’s current ThinQ pair and Haier’s last two badge-bearing models , now selling on clearance. Each spent days in a controlled chamber and nights cooling actual bedrooms, so every score you’ll see is rooted in both data and daily use.

Because Haier’s catalog now stops at 10 k BTU, we kept the fight fair—no larger LG Dual-Inverters here—focusing on the sizes where the brands still overlap. Every section follows a consistent rhythm—primer, LG, Haier, verdict—letting you compare in one glance and decide which unit best fits your window, wallet, and tolerance for summertime noise.
Conclusion
If you want a still-supported line with quieter operation, motorized airflow, and a guaranteed parts pipeline, pick LG.
If bottom-dollar pricing trumps everything and 8 k–10 k BTU covers your space, the last Haier-badge units deliver smart, bargain cooling—just remember they’re clearance for a reason.
