What Experts Love
- ✓ Rated for rooms up to 1,500 sq ft, more than 4x the coverage of the smallest pick in this roster, with 23,200 BTU of cooling and 16,000 BTU of supplemental heat in one chassis.
- ✓ Smart remote control covers scheduling without a phone, a genuine advantage for a shared living room or open-plan apartment.
- ✓ Sized for whole small-apartment cooling and heat rather than a single bedroom, which is a category most window units in this guide can't touch.
Common Criticisms
- ✗ Runs on 230V, so unlike the other picks here it needs a dedicated high-voltage circuit at the window, which usually means an electrician if your home doesn't already have one.
- ✗ 'Supplemental heat' means electric resistive heat, not a reverse-cycle heat pump, so it costs more to run per BTU of warmth than the Friedrich Kuhl's true heat pump.
