Amazing difference in the space.

This is a great unit for a garage, bedroom or other small spaces. My garage--where I keep a classic Camaro--is 400 square feet. Both the heat and AC functions work beautifully, as does the "dry" feature to regulate humidity.

My only wish was that the thermostat could be set for one temperature (automatic) and that the unit would know if you have to have AC or heat to maintain that temp. As it is, you switch the unit on cool and set a temp OR switch to heat and set a temp. It cannot switch on its own.
