A:Answer It adds heat to the room. Honeywell spec says "5 amperes", or 600 watts (think of the heat from 10 incandescent 60-watt bulbs). A similar Honeywell model is 759 watts, so thats a lot of heat when the refrigeration section is running. So most definitely Yes, it will kick out heat that your cooling system will have to overcome. Output temperature of the air is not a good indicator of the actual heat being put into the room, as low flow would feel like warm air while high output airflow might actually feel cool, both with the same amount of heat (and effect on room temperature). It's a major problem with hot, humid areas that use a/c for cooling, which is most applications!
