Yes it will heat up the air but not to the point of a 2000 watt heater. You can do about the heat other than put it outside or duct the air outside and make a temp insulated wall to block the heat. Of course then you are subject to heat loss in the winter and sucking in hot air. Other than that keep your filter as clean as possible. A clean filter means less work for the motor.
