It will usually be one of three things:
1. The vents are closed. Check that you can see up into the ducting. Usually there is a lever that opens and closes louvers behind the vent plate. If this is the case, you can open the louvers with the levers on the side of the vent plates to get your air. On older vents, the levers don't work very well, and may need replacement if this is the case. Not that you should, but I have opened the louvers with a screwdriver....It works....
2. A separated duct. Assuming that your ducts are overhead, the separation would be in the attic space.
3. An obstruction in the ducting. There may be a flapper that restricts air in one part of the ducting, forcing it more to the uther ducts. Sometimes these close off on their own accord and need to be reset for proper operation. An object in the ducting will cause the same problem.
I'd discuss this with your building maintenance team. The only item on this list that I'd take a crack at, if I were renting the apartment, is number 1. Even then, be very careful working on ladders. If you can see up into the vent, then there really isn't much else expected of you.
Hope this helps you. Regards, --W/D--

2012 Alpine 3700re. Why is the rear air main air outlet not blowing forced air?

Assuming you are talking about some kind of central forced air and not a roof air conditioner, I would say the hose fell off the outlet or the A/C unit itself. Do all the other vents blow cold air? If yes, remove the wall vent and look. If the hose is attached, go to the A/C unit and check there. Also, remote possibility some kind of critter got inside the hose and built a home, effectively blocking the airflow.

Not enough info on filters. Central air filter? Roof A/C filter? Engine air filter?

Manufacturers put so many different models of sleeper sofas in RVs, it's hard to tell which one you have. Your owner's manual should tell you. If you don't have one, look around. There might be a latch(s) somewhere. Or try pulling up and out or straight up.

If you are using this inside your home with central air running do you have to vent it to an outside window?

Yes, it must be vented to the outside, even if you're using central AC, too. The reason being is if you don't vent it to the outside, the hot air and humidity that normally goes thru the duct and out the window, will stay in the house and your Central AC will have to run longer and harder to overcome this rise in heat and humidity. In addition, the room that the portable AC is in, will get extremely hot & humid.

Hope this helped you. Please let me know. Thanks.

Amana central heat and air unit use to blow cold air through all the vents. Now the 2 hardest blowing vents close to the air handler barely even blow out cool air while all the other vents still blow very...

Visually inspect the duct run connections to the main trunk. It is possible that they have loosened and are losing air under the house. Also inspect the duct runs from the trunk connection to the vent connection. You want to check for any damage or other failure. It is rare to find dampers in individual runs in residential duct systems; however, it is another possibility.

I hope you find this information helpful. Good Luck in your endeavor! :-)

1999 Ltd. The right vents blow hot air but left vents blow cold

Yes go to you have to get the codes from your ATC controls first...Hold down the A/C button and the Recirculating button at the same time and while holding the two buttons turn you left temp. control up. It should give you codes if not then it will just read 00. Once you get those find out what they mean...20, 46,52,or 54 means you blend door(s) are stuck down and have to come up to allow heat to flow. Go to and it will tell you how to replace it or in my case I just fixed it by putting a screw in it to hold the doors up....But hey i'm cheap so i like quick fixer uppers!!! Try that and lemme know if it works...
