How we chose
How we chose
We compared the listed BTU ratings, square-foot coverage and current prices across the three Midea inverter models. Two are 8,000 BTU units and one is 10,000 BTU, and the coverage figures we could compare range from 350 sq ft to 450 sq ft.
The 8,000 BTU Smart Heat/Cool Inverter Window Air Conditioner is listed for spaces up to 350 sq ft at $379.00. The 10,000 BTU Duo Smart Inverter Portable Air Conditioner is listed for spaces up to 450 sq ft at $498.79. The 8,000 BTU SmartCool Inverter Window Air Conditioner with Remote Control is the lowest-priced of the three at $310.00, and it is the one model here listed without a square-foot coverage figure.
Those BTU ratings, coverage figures and prices are what separate the three: heating plus 350 sq ft of coverage at $379.00, 450 sq ft of coverage in a portable at $498.79, or cooling only at $310.00.
Who should skip these
Skip these if your room is larger than 450 sq ft. The largest coverage any of the three lists is 450 sq ft, so a bigger space falls outside what they are rated for.
Skip these if you need a unit without inverter operation. All three are inverter models, so none of them is a non-inverter alternative.
Also skip the two window units if you can't install a window unit. The 8,000 BTU Smart Heat/Cool Inverter Window Air Conditioner covers up to 350 sq ft at $379.00, and the 8,000 BTU SmartCool Inverter Window Air Conditioner is $310.00; both are window models. The 10,000 BTU Duo Smart Inverter Portable Air Conditioner at $498.79 is the one that doesn't need a window, and it covers up to 450 sq ft.
How to choose the right one
Start with coverage and BTU, since those decide whether a unit will actually cool your room. The 8,000 BTU Smart Heat/Cool Inverter Window model is rated for spaces up to 350 sq ft, and the 8,000 BTU SmartCool Inverter Window model carries the same 8,000 BTU rating. If your room is larger, the 10,000 BTU Duo Smart Inverter Portable is rated for spaces up to 450 sq ft.
Next, decide whether you want heating as well as cooling. The 8,000 BTU Smart Heat/Cool Inverter Window model adds heating for $379.00. If you only need cooling, the 8,000 BTU SmartCool Inverter Window model is $310.00.
Finally, match the installation to your space. Both 8,000 BTU models are window units, so they need a window that works for mounting. The 10,000 BTU portable is the option when a window install does not suit your room. It is $498.79.
