Re: should i open or close

Close the vent for maximum cooling. When you open the vent it opens a panel to the outside air and the unit cools less efficiently.

Hi there, I have a LG ac through wall/window unit LWHD1200FR 11,500 BTU. It's have a Open vent/Close vent mechanism by the front louver from where the cool air comes out. I would like to know what...

The OPEN is to be used when the air temperature is cool enough, not to have to use the AC. When it's open, the fan continues to operate and pulls cool air in from the outside and circulates it inside the room. Generally, this is only used at night, when temperatures are milder and there's less humidity. When it's CLOSED, the AC is in cooling mode and only the inside air is used to cool and is exhausted as needed. Hot, humid days & nights are when it should remain closed.

I hope this helped you & thanks for choosing FixYa.

Emerson quiet kool wall air conditioner. Should vent be open to remove humidity?

No - opening the vent will allow unconditioned outside air into the space and add to the humidity load.

Think of it like your car's A/C - when you put the controls to "Max A/C" the system recycles just the air inside the car and doesn't use any outside air. When the control is set to normal A/C, some outside (fresh) air is brought in.

The same thing is true for a window A/C unit. Keeping the vent closed will help the unit de-humidify and cool the air more quickly.

How do I stay warm in a cold office?

Multiple options here, but some may require maintenance worker to adjust.

1) Adjust thermostat. (Got to assume you don't have control of this, or the thermostat is set low to cool other areas and you freeze because of that.)

2) Close the vent in your office. Depending on type of vent, may be as simple as a slide handle, a twist handle, or some apparatus that must be adjusted.

3) Variation of #2 above, place a piece of cardboard in vent to partially or completely close off the vent.

4. OK, dress warmly. Not the greatest idea, but an option.

5. Perhaps the option of last resort, get a small heater and place under your desk to warm you. Need to be careful to not allow anything to contact it and start a fire, nor do you want to overload a circuit.

6. OK, least attractive of all options, change jobs.

Danby DAC5020 Air Conditioner fan works but not compressor

It could be as simple as being low on refrigerant. Depends on how expensive the unit is if its worth recharging and how big the unit is. Some small units will need to have a recharge point fitted which cost more of course.

F1 - F3 are the fan speeds when the air conditioner is in fan only mode.

The vent can be opened or closed based on your preference. When the air conditioner is in a/c or dehumidifier mode having the vent closed will cause the a/c unit to recirculate the room air and cool / dehumidify quicker. When you open the vent the a/c unit takes air from outside and cools / dehumidifies it. It is obviously not as efficient this way but it does bring in fresh air.
