Hot air coming out of back

I have a Maytag Portable air conditioner and the back is blowing hot air! Is there a certain hose I need to get for this?  The black hose down at the bottom left hand corner was cut so I got another hose and duct taped it together.  Then I put that hose out the window.  Am I doing something wrong?  I was given this air conditioner as a hand-me-down.

Portable air conditioners mainly have two hoses one hose is exhaust thats the one that is blowing hot air. the one pulling is return.. the hot air blowing out should be exhausted to the outside. the blowing air needs a hose and to be laid out a window the back should have model and serial maybe product number. the two holes are either 4 inch or three inch and most portable units other than hand me downs come with a window frame that allows the hot exchanged air to go outside and cooler air to be used for heat exchange.

Is my portable lg air conditioner suppose to be blowing hot air out of the back

it works the same as any air conditioner where if you go outside and place your hand at the fan then it will be blowing hot air
In the instructions it should say place the rear near an open door or window or use the hoses to move the hot air out of the room
air conditioner units are basic heat transfer units where they take the heat out of the room and transfer it to the outside and in the process remove the moisture from the air in the room which i turn makes it more comfortable

The blue snowflake is for the AC. The 3 fan icons are for low, medium, and high settings. The icon with the cup with over flowing water means empty the water tank. The cup next to the snow flake is the dehumidifier. The cup next to that means tank is empty and the clock is the timer. If the front part is only blowing out hot or warm air I say you got a broken one unfortunately. The back part blows out hot air which is why there is an exhost hose attachment.

Why is this blowing hot air out the back when the cold a comes out the front

The hot air is heat from the cooling compressor, while it's in operation. It's normal and should not be of concern, as long as the unit is cooling as it should and the host air is being exhausted out the flexible hose to the window.

Hope this answered your question and thanks for choosing FixYa.

I had to replace the exhaust hose (the one on the left) because the hot air from the previous season made it very brittle and it cracked when i took it off. Is this normal? Also, I replaced it with an...

I insulate the (hot) hose so the heat -- for sure -- goes outside. Any heat that returns into the room defeats the work to get it out of the air in the first place.

Using a dryer hose is fine if air doesn't blow out of the seams. Considering that the unit may cost $300/season to operate (just for the electricity) you might want to be sure the hot air gets out. I wrapped a blanket around the hose.

If the sun is on a hose that is not made of UV-stabilized material, it may become brittle. Side note: venting out to the sunny side of a room hampers the efficiency of the unit. Avoid operating the unit with direct sun on it.

Blows hot air

If your machine is an air conditioner then the little hose needs to drain condensation to the outdoors. Most of the time there is a pump that the hose is attached to inside the unit. If the overflow switch is open the compressor contactor will not operate but the fan will.

Does it need a hose to release the hot air

Yes, you need to have a hose on the outlet where the hot air comes out and run that out through and window or something to the outside.
If you do not do that it will not cool because you are just running the hot air back into your space that you are trying to cool.

Could be several things. Make sure evap coil is clear. Use a garden hose if you need to for the mud in the back. If both coils are (clean evap and condenser) Then it probally is short on refrigerant.

Rattling noises from ac

If you are careful unplug it, tilt it 45 degrees back and use a hose spray sideways to remove the debris from the coils. It worked for me. Be careful not to get any of the electrical parts wet.Low pressure from hose

Hoses for proper connection should have been included with your purchase. Without the hoses the set-up can not be done satisfactory. One is for fresh air supply and the other is the hot air exit hose. These are normally vented out a window. Check with the dealer where you perchased the unit from. If from a private individual contact them.
