- Interesting you mention leaving the dampers cracked—I've seen people shut them all the way and end up with weird airflow noises or even frozen coils.
- About those dust bunnies, have you checked your filter lately? Sometimes if it’s clogged, dust just keeps cycling back in.
- Did you ever try using vent deflectors, or is it mostly just trial and error with the dampers for you? I’ve seen mixed results with those…
Never had much luck with vent deflectors myself—sometimes they just push the problem around instead of fixing it. Dampers can help, but you’ve got to be careful not to close them too much or you risk pressure issues or, like you said, frozen coils. Ever checked your return vents for blockages? Sometimes furniture or curtains can mess with airflow more than folks realize. And yeah, a dirty filter will absolutely keep dust in circulation... seen that way too often.
