I am close to installing 3 fujitsu mini split units at our home under construction.
Wall mounted mini split outdoor unit placement.
When to choose a wall mounted unit.
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.
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.
There is no single way to install a mini split with each install different needing to match the home and climate.
The outdoor unit is water resistant not waterproof.
Mini split systems are ideal for average sized rooms with at least 7 8 high ceilings.
This wall must lead to the outside since you ll be running refrigerant lines from the indoor unit to the outdoor unit.
Placement of this component comes first in ductless mini split installation because it influences where the outdoor unit goes.
What about placement of the outdoor component.
It is also the quietest choice.
The most common method for installing a mini split outside condenser is on the ground but it can also be installed on a wall.
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.
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.
Rain itself will not have a major impact on the performance of the unit.
Pros and cons of a wall mounted mini split.
Two outdoor units will be installed near each other with the third installed in a different area of the house.
Mounting too low can hamper air distribution.
They need to be mounted high on the wall approximately 6 feet high.
The unit s location should fit well aesthetically with other features in the room such as windows.
If your location is prone to flood consider a mini split stand wall mounting or roof mounting.
For aesthetics sake any indoor unit installed above a window should also share symmetry with said window.
A wall mounted unit should be installed 8 to 10 feet from the floor.
Installation should typically be performed at least six feet from the floor.
Place the bracket designed to hold your wall unit in place in the desired location.
Wall mounted types this is the most common type of indoor unit because it is the most affordable most energy efficient and most powerful option.
Both methods have their pros and cons.
The hvac installer asked if i wanted to mount them on the wall or on the ground.
Use a level to make sure it s straight.
A condenser unit should always be placed outside where it has unlimited access to outdoor air.
