A system that allows fresh air to be brought into a furnace as part of the return air circuit. This not only helps to replace stale air within a home, it also provides adequate air supplies to establish enough positive pressure within the dwelling to prevent air infiltration around windows, doors, forced air registers and around room perimeters of rooms along the baseboards. The system consists of a furnace that has a return air supply duct, an intake louver and filter for bringing fresh air into the system, an intake fan mounted to the intake, an intake duct that brings the fresh air from the intake louver to the furnace and a motorized damper, installed in the intake duct, to control the flow or air. These components are controlled by a control panel that works with the thermostat and furnace controls to operate the intake fan and damper as for optimum operation.

1. A method of mixing air in an interior space when not conditioning the air by an air conditioning system having a return air duct a circulation fan, and a thermal conditioning element, an outside air damper connected to an external air duct, an outside air intake fan, installed in said external air duct, the external air intake duct being connected to the return air duct of the air conditioning system, comprising the steps of:a) activating said outside air damper and said circulation fan for a pre selected operating time, independent of said thermal conditioning element;b) pulling outside air into said external air duct;c) mixing said outside air into the return air duct, of said air conditioning system, producing a quantity of mixed air;d) distributing the mixed air into a closed space;e) shutting down the circulation fan after a predetermined operating time;f) keeping the circulation fan shut down for a pre-selected quiescent time; andg) repeating steps a-f for an extended period of months. 2. The method of claim 1, further including: the step of closing the damper when the circulation fan is shut down. 3. The method of claim 1, wherein the air conditioning system includes at least one of: a cooling means, a heating means, and an air cleaning means. 4. The method of claim 1, wherein the air conditioning system further includes a thermostat. 5. The method of claim 4, further comprising the steps ofa) setting said thermostat to a desired room temperature setting;b) connecting said thermostat to an operating control for said thermal conditioning element;c) operating said thermal conditioning element when said desired room temperature varies from the desired room temperature setting;d) causing said circulating fan to operate independently of said pre-determined operating time; ande) shutting down said thermal conditioning element when said desired room temperature setting is reached. 6. The method of claim 5, further comprising the steps of:a) determining the status of the predetermined operating time; andb) shutting down the circulating fan if the predetermined operating time is the quiescent predetermined operating time; orc) operating said circulating fan if the predetermined operating time is the operating predetermined operating time. 7. The method of claim 1, wherein the air conditioning system further comprises a damper motor. 8. The method of claim 7, further comprising the steps of:a) causing said damper motor to open said damper at said pre-determined operating time; andb) causing said damper motor to close said damper at said pre-determined quiescent time. 9. The method of claim 1, wherein the air conditioning system further comprises a smoke detector, installed in said duct, and a means for overriding said means for controlling the operation of said return air duct in operable communication with said smoke detector. 10. The method of claim 9, further comprising the steps of:a) causing said air conditioning system to shut down upon detection of smoke in said duct by said smoke detector.
