What Is an Indoor Air-Handling Unit (Head Unit)?
The indoor air-handling unit, sometimes called a head unit, is the wall-, ceiling-, or floor-mounted component of a ductless mini-split system installed inside a room. It contains a coil and fan that condition and circulate air for that specific zone.
Why It Matters to You
The number and placement of indoor units determines how well a mini-split system covers your specific rooms — this is a design decision worth discussing before installation, not after.
Practical Guidance
Keep the area around an indoor air-handling unit unobstructed by furniture or curtains so airflow isn't restricted.
