Is it alright to continuously run the HVAC air handling system?
It is recommended to have the air-handling fan run continuously to achieve the most efficient operation of the air-handler or furnace. Continuously circulating the air in a home will reduce the effects of stratification. Stratification occurs when air becomes stagnant and all the hot or warm air remains in the top of a room and all the cool air settles in the bottom of a room. This settling of air will cause the thermostat to read inaccurately and the air-handler will run when it is not really needed. If the air-handling fan is running, air in the home will be “mixed” and temperature will be dispersed evenly. The thermostat will then provide more accurate results and heating and cooling will require less energy. Running the air-handler fan all the time will also provide the most efficient operation of the HEPA system. Although the HEPA system runs independently from the air-handler and has its own fan, the air-handler has the capability to draw air from the far ends of a home and bring
