I live in a one bedroom apartment.There are high wall vents for heating and air-conditioning-two in living room,one in dining room,one long one in hallway facing living/dining area,and one in each bathroom and bedroom.is the closure lever that flips up/down enough to save energy costs,or do I need to buy magnetic cover? Or does closing one just force the air to the other vents? Thanks

Unless you are closing rooms off completely, it won’t make a difference. If you lived in and old leaky house with bedrooms that you never used, closing off rooms would make sense. But a 1BR, you are just mixing the air anyway when you go from room to room.
A ceiling fan helps out in both Summer and Winter. In Winter, it pulls the warm air that has risen to the ceiling back down. The energy to run one is far less than that of an A/C. But using both at the same time means that you can set the A/C at a higher temp and feel as cool as if you had it a few degrees cooler.
Additional Details:
Yes, your additional details assumption is correct. Also, you can use insulated curtains year-round and close them during the day in the summer– particularly on south-facing windows. If you can stop the heat from building up inside, then you don’t have to pay to cool it down.

Where is your thermostat? If it’s in the living room & it’s pretty much open to the other areas of the apartment, there’s not much you will accomplish by blocking the vents. Only rooms that open to another hallway/room by door will be affected by shutting the vents (and the doors). Which in a 1 bedroom apt is probably only your bedroom and the bathroom, not the rooms I want no A/C in! If it’s tolerable, bumping up your A/C by a few degrees & running your ceiling fans is cheaper than keeping your A/C at let’s say 72 degrees. We use our central A/C much less by running fans in the windows at night when it’s cooler. Then in the morning, we shut the windows and close all the curtains and run the ceiling fans to help circulate the air. It stays relatively cool then. If it’s not cooling down very well at night or it gets up to 90 or hotter outside, then the A/C usually does go on then.
The Dept. of Energy web page has a ton of information on this subject.

HVAC Tech.: The ceiling fan will save you money, Blocking off the air grills will NOT. You FEEL cooler under the ceiling fan so you can set your thermostat toward the warmer side by 4 to 6 degrees and not notice the difference until your light bill arrives. then you can see the savings without any loss of comfort.Keep Kool!
