We live in a small apartment and the AC doesn't reach the bedroom. My parents sleep in the living room and make a lot of noise at dawn when they get ready for work so that would disturb the budgies sleep. Plus it gets way too cold over there. I sleep in the bedroom with a small fan that barely keeps me cool at night so I'm sure my budgies feel worse especially since the cage is covered with a thin blanket. The bedroom door is open and I don't cover the sides of the cage to let some air flow.
