Question

Ceiling Vent settings


I discovered a second set of flaps inside the ceiling vents - in some rooms they were closed and in others they were open. I opened all of them and since then the HVAC is not working right. It turns on and blows cool air for a few minutes then switches to just the fan blowing. It goes back and forth and the building temps keep climbing. Did opening those inner flaps have anything to do with this? Should they be opened or closed?

Nope. Opening the dampers in vents will nat cause the a/c to stop operating and only run the fan. You have something els going on now.

Unless the room the t-stat is in is over cooling and you are running on a constant fan setting.
