AC fan on?
Is it OK to leave the AC fan on continuously? Or, overnight...for white noise? We used to do this with our pop up, but the thermostat and AC unit were a different kind.

Remove return air filter.look inside and you will see evap coil.
Well, then the insulation must stink on mine. If I put on the blower when it's cold outside, I get some pretty cold air coming out of the vents, just as if the compressor was running.
The hot oustide air doesn't suck up all the cold air because the cold is being generated by the evaporation of the refrigerant. And hotter air is being blown out the other end of the system at the condenser coil. If that system isn't running, it'll scavenge heat from anywhere.
Then you might want to check the evap coil enclosure.
Mine has insulation and the corners/seams/screws are covered/sealed with insulating tape (which I redo every time I open evap coil cover)so the evap coil area stays cold when A/C is running.
In winter.with A/C fan running the warm air is pulled up thru evap coil and then warm air comes out of A/C ducts cause evap coil is not in service and enclosure is sealed from outside.
Nice way to circulate the furnace air.
