YES! I never even thought of that route!! Well, I went to the website and I looked at them, and they are exactly like you said.... pretty much all in one.... Theres even an auto feature that utilizes all at the same time.... So I guess my next question is.... is this thing efficient enough to really push enough Air conditioning in the Dead of Summer, and enough heat in the frigid winter into the 3 rooms? If so, is one gonna do it? Or do I need more than one? The biggest I found was 14,000 BTU... Thanks
