    Great heat pump window unit for South US climates

    This unit works great all year round in Southern US climates and generally punches above its weight. Super-efficient Heat in the winter, and excellent Cool in the summer. However, it is NOT for heating in Mid or Northern US climates where winter temps approach 40 or below. There are other heat pump window units that can handle colder weather, but not this one. It is relatively quiet and is both app/wi-fi and remote controlled. As long as you know all this going in, you will be happy with it.

    This ISN'T A HEATER

    They wrote this in such away that you think it heats, but if it's 41°F or under outside it specifically says it will not heat on the unit. Why even advertise it as that with the option.

    Great Window Unit

    Excellent product; however, when ambient temperature is below 40 degrees, the heater doesn't produce heat.
