I am trying to make sure I am understanding the research/studies behind using just the fan to help reduce energy to cool/heat home.
Nest has the option to set a schedule to run the fan in home to circulate the air, or for A/C it has an, "Airwave" option to get the room the thermostat is located to temperature, and then run the fan after to balance out the home temperature. I try to compensate this with balancing the registers in the summer using the dampers.
My HVAC system has an intake inlet on the exterior that almost looks like a bathroom exhaust fan exterior outlet, so it's a good size. My home is a new construction home, built 1.5 yrs ago. The house is sealed up pretty well, so I guess this is to make sure enough fresh air is coming in the home.
Now, will this type of HVAC system have the opposite effect of running just the fan trying to balance the air in the home? I imagine while trying to balance the air and bringing in outside air at the same time, it may just do the opposite and make the temperature go the opposite way even more, respective of what system is running (Furnace/AC).
I have a whole house humidifier that kicks on just the fan when more humidity is needed, but it's hooked up to the hot water line, so maybe that helps balance the temperature difference.
Is the outside air coming in enough to cause the heating/cooling system to kick on more? Or is that air usually minimal? Trying to understand the effects of just running the fan with this type of system has on temperature in the home.
