If the unit has been stored on its side or shipped that way, it should be turned to a horizontal orientation for at least 24 hours prior to running the unit. This allows sufficient time for any oils and lubricants to resettle back to their proper levels, providing protection for internal gears and moving parts.

In summary, while you may be able to temporarily lay a portable air conditioner on its side, it is not recommended to turn any type of air conditioner on its side for an extended period. It is always best to follow the manufacturer’s instructions and guidelines to ensure the safe and proper use of your air conditioning unit.

Why Air Conditioners Should Be Used in an Upright Position?

Air conditioners are designed to be used in an upright position, and for good reason. To understand why air conditioners should be used in an upright position, it is important to understand how they work.

Air conditioners operate by drawing in warm air from the room, passing it over a set of coils that are filled with a refrigerant, and then blowing cool air back into the room. The refrigerant absorbs the heat from the warm air and carries it outside, where it is released into the atmosphere.

When an air conditioner is turned on its side, the oil that lubricates the compressor can flow into the refrigerant lines, which can damage the compressor and cause it to fail. Additionally, the refrigerant lines are designed to be used in an upright position, and turning the unit on its side can cause refrigerant to flow back into the compressor, which can also damage the unit.

Furthermore, turning an air conditioner on its side can cause the refrigerant to become trapped in the wrong part of the system, which can result in poor performance or even total failure of the unit. It is also important to note that turning an air conditioner on its side can cause water to flow into areas of the unit where it is not meant to go, potentially causing water damage and corrosion.

In summary, air conditioners should be used in an upright position because turning them on their side can cause damage to the unit’s compressor, refrigerant lines, and overall performance. If you need to move or transport your air conditioner, it is important to take proper precautions to avoid turning it on its side.

This may include securing the unit in an upright position and using a dolly or other equipment to transport it. By following these guidelines, you can ensure that your air conditioner remains in good condition and functions efficiently for years to come.

Types of Air Conditioners

There are three main types of air conditioners: window air conditioners, central air conditioning units, and portable air conditioners. Each type has its own unique features and functions, and the rules for turning them on their side may vary depending on the type of unit.

Window Air Conditioners

Window air conditioners are designed to be installed in a window and are a popular choice for cooling individual rooms or small spaces.
