Bests & Worsts Reviews from Amazon

Great window heat pump if you understand how it operates and some of its limitations. First off in regular cool mode this thing will maintain the room temperature perfectly. The eco mode tends to cause some slight temperature swings since it's only sampling the air every 10 minutes. Easiest way to offset ecomode temperature swings is to set it about 2 degrees below what you normally set it. If you live in a very humid environment be careful with eco mode because the coils never get a chance to dry out and can cause your ac to get moldy and smell since the fan doesn't run full time and dry the coils on the compressor off cycles. Also like any window ac the side panels that help seal the window up are terrible. The best solution I've found so far is to get a sheet of the foam paneling at your local box box store and install the window ac and cut the foam panel to size, then take some clear rtv and seal any gaps. This will provide and nice airtight and leak free seal, far better than those acordion panels. Now as far as heatpump this unit will work great down to about 35-40f, then the unit will switch over to heat strips. When this happens you will go from 7000btu heat output to roughly 3500btu. The reason they do this is because at 35f there isn't as much heat in the air and you would need to incorporate defrost controls into the system. I'm explaining this so you can understand in heat mode down to 35f you will have full heat output and below 35f your heat output will cut in half. Oh and just remember every year pull the unit out of the sleeve and clean the coils. I like to clean the coils in the spring that way I can go into the summer with clean coils.
