A method of heating or cooling a room of a building includes providing supplemental warmer or cooler air to the room with an inline duct supplemental heating and cooling device mounted along an air duct that supplies the room with air from a main furnace and/or cooling unit associated with the building. A thermostat is used to set a desired temperature for the room, and a controller of the supplemental heating and cooling device is in communication with the thermostat, and activates an electric heater and/or fan as appropriate to warm or cool the room as needed. When the device is used to cool the room, the fan may be operated to draw cooled air through the duct from the main cooling unit and/or from other areas in the building that are linked via ductwork.

1. A method of heating and cooling a room that is primarily heated by a furnace adapted to supply heat to the room through an air duct, and that is primarily cooled by a cooling unit adapted to supply cooled air to the room through the air duct, said method comprising: directing substantially all of the air from the air duct into a fluid passageway defined by a housing of a heating and cooling device that is positioned in-line with the air duct, the housing containing a heater and a fan disposed in the fluid passageway, whereby substantially all of the air in the fluid passageway is received from the air duct and is directed through the heater and the fan;controlling the heater and the fan of the heating and cooling device with a controller that is in communication with a thermostat positioned in the room;selecting a desired temperature in the room at the thermostat;automatically activating the heater with the controller when the temperature detected in the room by the thermostat is lower than a threshold minimum temperature corresponding to the selected desired temperature;automatically activating the fan with the controller when the temperature detected in the room is lower than the threshold minimum temperature;supplementing the cooling unit associated with the air duct by activating the fan, without activating the heater, to draw air previously cooled by the cooling unit through the air duct with the fan when a temperature in the room is higher than a desired maximum temperature, thereby supplementing the cooling unit associated with the air duct; anddischarging substantially all of the air in the fluid passageway of the heating and cooling device into the room. 2. The method of claim 1, further comprising automatically deactivating the heater when the temperature detected in the room is approximately equal to the desired temperature. 3. The method of claim 1, further comprising automatically deactivating the fan when the temperature detected in the room is approximately equal to the desired temperature. 4. The method of claim 1, wherein said automatically activating the fan and said automatically activating the heater comprises selectively activating the heater and the fan with a wireless thermostat that is in wireless communication with the controller. 5. The method of claim 1, further comprising positioning the heating and cooling device in-line with the air duct by coupling a vibration insulator sleeve, which includes a hollow fabric member, between the housing and the air duct. 6. The method of claim 1, wherein said activating the fan without activating the heater comprises generating a fan-activation signal at the thermostat and receiving the fan-activation signal at the controller. 7. A method of heating and cooling a room that is primarily heated by a furnace adapted to supply heat to the room through an air duct, and that is primarily cooled by a cooling unit adapted to supply cooled air to the room through the air duct, said method comprising: mounting an electric heating and cooling device in-line with the air duct, the electric heating and cooling device including a heater and a fan disposed in a fluid passageway defined by a housing that is coupled to the air duct;directing heated or cooled air, from the furnace or the cooling unit, through the air duct so that substantially all air passing from the furnace or the cooling unit through the air duct is directed through the fluid passageway, the heater, and the fan, so that substantially all of the air passing through the electric heating and cooling device is received from only the air duct regardless of whether either of the fan or the heater is operating;adjusting a thermostat that is in communication with the heating and cooling device to select a desired temperature in the room;detecting a temperature in the room with the thermostat;automatically activating the heater and the fan when the temperature detected in the room is lower than the desired temperature, to propel heated air generated by the furnace and the heater to the room through the air duct; andactivating the fan in response to a fan-activation signal, without activating the heater, to propel air through the air duct that was previously cooled by the cooling unit and is at a cooler temperature than the temperature detected in the room by the thermostat, thereby supplementing the cooling unit associated with the air duct. 8. The method of claim 7, further comprising automatically deactivating the heater when the temperature detected in the room is higher than or equal to the desired temperature. 9. The method of claim 7, further comprising automatically deactivating the fan when the temperature detected in the room is substantially equal to the desired temperature. 10. The method of claim 7, further comprising selectively activating the heater and the fan with a wireless thermostat that is in wireless communication with a controller. 11. The method of claim 7, further comprising: detecting a temperature of air discharged from the heating and cooling device with a discharge air temperature sensor mounted at the housing; andautomatically deactivating the heater when the discharge air temperature sensor detects that the temperature of the air discharged from the heating and cooling device is higher than a selectively chosen limit temperature. 12. The method of claim 7, wherein said mounting the heating and cooling device in-line with the air duct comprises coupling a vibration insulator sleeve, including a hollow fabric member, between the housing and the air duct. 13. The method of claim 7, wherein said activating the fan without activating the heater comprises generating the fan-activation signal at the thermostat and receiving the fan-activation signal at a controller. 14. A method of heating and cooling a room that is primarily heated by a furnace adapted to supply heat to the room through an air duct, and that is primarily cooled by a cooling unit adapted to supply cooled air to the room through the air duct, said method comprising: positioning an electric heating and cooling device in-line with the air duct, the electric heating and cooling device including an electric heater and an electric fan disposed in a fluid passageway defined by a housing;directing substantially all of the air passing from the furnace or the cooling unit through the air duct through the fluid passageway, the electric heater, and the electric fan;selectively adjusting a thermostat that is in communication with the heating and cooling device to a temperature desired in the room;detecting a temperature in the room with the thermostat;automatically activating the electric heater and the electric fan when the temperature detected in the room is detected by the thermostat as being lower than a threshold minimum temperature corresponding to the desired temperature;activating the electric fan in response to a fan-activation signal, without activating the electric heater, to propel air through the air duct that was previously cooled by the cooling unit and is at a cooler temperature than the temperature in the room, to thereby supplement the cooling unit associated with the air duct; anddischarging substantially all of the air in the fluid passageway of the heating and cooling device into the room. 15.
