Summary: To understand this unit you have to understand how ptacs with heat pumps work. The watts usage they list in website only indicates if your heat pump is working at the moment. (Do some research). In my mind i thought it will have the heat pump working right away. Except when it's below 26 degrees F.
Summary: I exchange this model with an older one that was so noisy you had to turn the tv volume up to hear..I was amazed how easy it was to replace, me and my daughter took out the old one and put the new one in ..It took approximately 10 minutes.
Summary: I want to love it BUT. Purchased in January to heat our 4 season sun room and worked like a charm. In July when we tried to use the A/C it would cool and then cycle to heat mode. After 3 repair visits it was finally repaired, under warranty.
