The Midea Duo is a portable air conditioner with heat pump heating and an inverter. It suits rooms where a window unit will not fit, such as sliding or casement windows. It has about 260 Amazon ratings and sells for about $630.
What You Need Before You Buy
- A window for the hose kit. The listing’s window kit fits openings of about 20 to 64 inches.
- A standard 115V outlet.
- Floor space next to the window. It weighs about 77 pounds, on wheels.
Installation, Climate and Shipping
Setup is DIY: fit the window panel, connect the hose and plug it in. No electrician needed.
The listing says heat pump heating works from 41°F to 86°F outdoors. Below 41°F it will not heat, so it is for mild weather and shoulder seasons.
Shipped and sold by Amazon. Delivery was showing about 2 weeks out when I checked, with no freight fee.
