Guide On How to Close Vent on LG Air Conditioner

Step One: Turn off the Air Conditioner

The first thing to do when you want to close a vent in your Lg air conditioner is to turn it off. For this process to work, you must make sure the unit is powered down. Sometimes, though not all the time, closing a vent will decrease airflow through your system and therefore cause the unit to overheat. The best way to do this is to turn off the unit and let it cool down for a few minutes.

Step Two: Clean Out the Vent

Once you have turned off your Lg air conditioner, it’s time to clean out the vent that you want to be closed. Sometimes, there will be debris stuck in the vent that is blocking airflow. All you need to do is take out the grate and vacuum out the inside of the vent.

Step Three: Cover the Vent

Once you have cleaned out the vent, it’s time to cover it up so that no outside air enters your system. You can use tape to block out any gaps or holes in the vent if necessary.

Step Four: Turn on System

Now, you must turn your Lg air conditioner back on and allow it to run at a low setting. Keep an eye on the unit to see how it is running, and if you notice that it seems to be working harder than normal, turn off the system again.

If your Lg air conditioner still doesn’t have enough cold air after letting it run for 30 minutes with the vent closed, open up the vent and start the process over.

Step Five:  Check for Air Leaks

If you’ve tried all of the steps mentioned above and the air conditioner still isn’t reaching its full potential, it’s time to check for air leaks. You might not notice these until your system is running at full capacity, though.

When you begin to feel cold air coming out of your vents, put a lit candle up to the vent. If you notice that air is coming through, you can put some caulk or weather stripping around the area to prevent losses in the future.

Step Six: Check Filter

The final thing you can do is to check your Lg air conditioner’s filter. If the filter isn’t clean, it will reduce airflow through your system and cause inefficiency in performance. The easiest way to solve this problem is by simply replacing the filter. However, if you decide not to replace it, make sure that you clean it with soap and water to ensure that it can do its job.

Step Seven: Check the Drain Hose

Lastly, if you’ve checked all of the other possible causes and your unit still isn’t working properly, it’s time to check the drain hose. As mentioned before, closing a vent will cause airflow through your system to decrease. For this process to work as efficiently as possible, there needs to be enough airflow to carry moisture out of the unit. If you find that this isn’t happening, check your drain hose.

Should My Air Conditioner Vent Be Open or Closed?

Open it! If you’re not getting any cooling air, then you probably have a blockage somewhere. This is because the condensation inside the unit needs somewhere to drain (not everywhere will be ideal), and this is most likely caused by one or more vents being blocked with insulation, dirt, furniture, etc.

Be sure to check every vent on the outside of your unit, as well as the supply and return vents that run through your house. If you have a heat pump, make sure to open both the intake and outtake vents for it.

The outtake vent is the one closest to where the air comes out on your registers, while the intake vent is located behind or under your air conditioner. So if you’re not getting any cooling air out of your registers, then it’s a good indication that the intake vent is blocked!

How Many Ac Vents Can I Close?

In general, most homeowner’s HVAC units have two vents that exhaust hot air out of the house. This means you can only close one of them, if at all.  If you have a heat pump unit, there may be additional vents for the outdoor compressor to pull in cool air from outside your house.

This is why, if you have a central air system, there’s usually only one actual “air conditioner” unit with vents on each floor of your house. Having said that, both vents are not always used to expel hot air from the inside of the house.

This will be the case if you have a heat pump system.  In this instance, closing one of the vents will not affect your overall cooling capacity; it simply means that the outside compressor unit will draw in air from a single vent instead of two.
