Pros and cons of a wall mounted mini split.
The most common method for installing a mini split outside condenser is on the ground but it can also be installed on a wall.
Mounting too low can hamper air distribution.
Both methods have their pros and cons.
Look for a spot that isn t blocked by furniture.
This wall must lead to the outside since you ll be running refrigerant lines from the indoor unit to the outdoor unit.
Keep an open space available for the outdoor unit preferably on a terrace or awning above the wall so the compressor and condenser receive unhindered airflow.
For aesthetics sake any indoor unit installed above a window should also share symmetry with said window.
A condenser unit should always be placed outside where it has unlimited access to outdoor air.

When to choose a wall mounted unit.
Place the bracket designed to hold your wall unit in place in the desired location.
However the unit should never be placed in an area where there is standing water.
Placing a condenser unit indoors in an attic or garage will reduce your system s air supply which will limit the amount of heat that it s able to remove from your home.
Rain itself will not have a major impact on the performance of the unit.
A wall mounted unit should be installed 8 to 10 feet from the floor.
What about placement of the outdoor component.
There is no single way to install a mini split with each install different needing to match the home and climate.
Installation should typically be performed at least six feet from the floor.
The unit s location should fit well aesthetically with other features in the room such as windows.

Floor mounted types this is a great option as well because we find there are some cases when we cannot use a wall mounted option.
Two outdoor units will be installed near each other with the third installed in a different area of the house.
Mini split systems are ideal for average sized rooms with at least 7 8 high ceilings.
The outdoor unit is water resistant not waterproof.
A ductless system delivers air directly from its indoor air handler so the unit should be placed in the room where you want most of your heating and cooling.
