Most air conditioners need to be tilted half an inch while being installed. Because window air conditioners are large and heavy, make sure to enlist assistance when installing them. Typically, they feature bracing brackets. You should buy a set on your own if your new AC didn’t come with any.

Install the air conditioner in the window with assistance. Push it back until the window reaches the front metal flange. It’s now time to secure the brackets with screws. To tilt the unit somewhat lower on the outside area of the window, place one on the left side and one on the right.

You may be questioning why the tilt is required in the first place at this point. Water drips from window air conditioners. The drip will land on the outdoor ground if the machine is properly angled. The water will leak into the air conditioner and possibly down the interior wall of your home if it is not angled sufficiently. You will need to adjust your air conditioner if this occurs. Mold and other sorts of water damage can occur if water drips inside for an extended period of time.

Does Every AC Unit Leak Water?

You might start to worry that your air conditioner is dripping excessive amounts of water. Since each unit will leak more or less depending on the size of the air conditioner, how much you are operating it, how hot it is outside, and how much humidity is in the air, there is no right or incorrect response to this question. Your window air conditioner may leak up to two liters of water on a particularly hot day.

You must determine why your AC isn’t dripping water. All air conditioners drip to release the accumulated moisture inside the unit. The majority of the water should drop from the back of the AC, however some will still be on the inside to cool the heating coils. The air conditioner won’t drip water, though, if it is not turned on.

If your air conditioner is not leaking any water at all, there may be a clog or it may not be dehumidifying your room. In this situation, you might need to get in touch with an expert to look at your air conditioner or it might be time to get a new window unit. However, carefully examine it to see whether water is leaking from other places, such as the front of the unit, before concluding that it isn’t dripping. You should probably tilt the chair back further in this situation.

If readjusting the tilt doesn’t stop the leak, you could not have properly sealed it in place. The area where you inserted the air conditioner into the window shouldn’t have any air pockets around it. Verify the siding’s stability. Use some caulk to close off the air pockets if you discover that this is the issue.

How Does A Window Air Conditioner Perform When Turned On Its Side?

Your window air conditioner should never be positioned on its side. It shouldn’t be stored on its side or positioned on its side in a window. The parts inside the device will be harmed if you do that.

Your window air conditioner’s compressor needs oil to stay lubricated. When put correctly, the oil covers the compressor in a uniform layer. The compressor will only have oil on one side if the air conditioner is installed on its side, starving the other parts of lubrication. This will eventually result in the compressor burning out.

Ventilation grates surround the sides and bottom of your window air conditioner. The way an air conditioner operates is by removing hot air from a space and dumping it outside. If the appliance is mounted horizontally, rainwater will enter the ventilation grates and obstruct airflow, damaging the equipment.

As mentioned previously, the water that drops from your air conditioner should fall outside. The water will not drip properly if your air conditioner is inserted into the window on its side. It could damage your window unit by leaking into the home or internally into the air conditioner.

The oils and other lubricants will concentrate in one location of the air conditioner when it is stored on its side, as was already indicated. Even while it’s ideal to entirely avoid this situation, it could occasionally be inevitable. Unaware of the potential harm, a motorist might ship it on its side or a relative would store it that way.

Don’t freak out if you ever find yourself in this predicament. Place your air conditioner correctly on a level platform before replacing it. For at least 24 hours, leave it there. This will give the oils some time to return to their proper locations inside the machine. It is okay to put the air conditioner in your window and turn it on when this time has elapsed.


All window air conditioners drip water from the back; if your air conditioner is not dripping, there is a problem. Window air conditioners are designed to remove heat and humidity from the room and replace them with cold air. They must be properly installed with the back slightly tilted to allow for dripping condensation.
