Not sure which way those little duct handles are supposed to point?
Here’s your quick damper cheat sheet:
☀️ Summer: Open your upstairs dampers fully to help get more cool air where the heat likes to rise.
❄️ Winter: Partially close upstairs dampers so more warm air stays on the lower levels first.
Remember: handle parallel to the duct = OPEN. Handle perpendicular = CLOSED.
Call if you think you need a little seasonal adjustment from your Cool Neighbor. 😎
