Abstract
An inline duct supplemental heating and cooling device provides heated and/or cooled air to a room in a building to supplement the heating provided by the existing furnace or the cooling provided by the existing cooling unit in the building. The device includes an electric heater and fan that are activated and deactivated individually by a controller, which receives room temperature data from a thermostat. The device may include one or more separate safety devices to prevent overheating of heater air or of the device itself. Optionally, a vibration-insulating sleeve may be used to couple the device to an existing ventilation duct of the building.
