How we chose

How we chose

We looked at the three Midea U-Shaped Smart Window Air Conditioners and compared them on three things: BTU rating, stated square-foot coverage, and current price. The 8,000 BTU model is rated for spaces up to 350 sq. ft. and costs $399.99. The 10,000 BTU model is rated for spaces up to 450 sq. ft. and costs $449.99. The 12,000 BTU model is rated for spaces up to 550 sq. ft. and costs $509.99.

The price gaps follow the capacity steps. The 10,000 BTU unit costs $50.00 more than the 8,000 BTU unit, and the 12,000 BTU unit costs $60.00 more than the 10,000 BTU unit. Between the smallest and largest, the difference is $110.00.

That left the sizing decision to coverage. The 10,000 BTU unit sits in the middle at 450 sq. ft., which is why it is our pick for most rooms. If your space is up to 350 sq. ft., the 8,000 BTU unit covers it for less. If you need up to 550 sq. ft., the 12,000 BTU unit is the one that reaches it.

Who should skip these

If your room is larger than 550 sq. ft., skip these. The largest of the three, the 12,000 BTU model, covers up to 550 sq. ft., so anything bigger needs a different unit.

Skip these too if you want a conventional window air conditioner rather than the U-shaped design. All three are U-shaped units: the 8,000 BTU model covers up to 350 sq. ft., the 10,000 BTU model up to 450 sq. ft., and the 12,000 BTU model up to 550 sq. ft.

On price, the three sit close together. The 8,000 BTU model is $399.99, the 10,000 BTU model is $449.99, and the 12,000 BTU model is $509.99. The 10,000 BTU model costs $50.00 more than the 8,000 BTU model, and the 12,000 BTU model costs $60.00 more than the 10,000 BTU model and $110.00 more than the 8,000 BTU model.

How to choose the right one

Start with the size of the room. The 8,000 BTU model covers up to 350 sq. ft. and costs $399.99. The 10,000 BTU model covers up to 450 sq. ft. and costs $449.99, which is $50.00 more than the 8,000 BTU model. The 12,000 BTU model covers up to 550 sq. ft. and costs $509.99, which is $60.00 more than the 10,000 BTU model and $110.00 more than the 8,000 BTU model.

If your room is up to 350 sq. ft., the 8,000 BTU unit is the match. If it is up to 450 sq. ft., go with the 10,000 BTU unit. If you need up to 550 sq. ft. of coverage, choose the 12,000 BTU unit.

All three are U-shaped window units, so the window can still open. Pick the BTU rating that fits your square footage, then let the price gaps decide how much you want to spend.
