Midea 8,000 BTU Inverter with Heat
#8 in WindowFull review
A good fit for a 350 sq ft room that needs cooling in summer and some heat in the shoulder seasons. The inverter keeps it efficient and fairly quiet.

3.5/5
For someone who wants a safe, view-friendly saddle unit with smart controls and has a shallow sill. Conventional inverter units cool as well for far less.

A solid inverter pick for a bedroom up to 350 sq ft if you value the two-year warranty. Otherwise the TCL Q-Series does the same job for less.
