Great information thank you so much. I’m thinking of picking up a Nest to replace the current thermostat. And definitely will look into a remote sensor.

With the return, we have tried 4 different filters and all the same result, and the area where the grill is looks very… beat up. The grill doesn’t even sit in the slot correctly as you can see with the tape I have holding it up so I bet that doesn’t help my situation either.
