Split or Portable

A split air conditioner separates the indoor and outdoor units. Only the quiet wall-mounted unit remains in the room; the data sheets list a sound pressure level of 19 to 22 dB on the quietest setting. According to the catalog, the 12,000 BTU split sets cool at 3.3 to 3.5 kW and also provide heating. They require a wall-mounted vent and installation by a certified professional; this also applies to the Quick-Connect sets with pre-filled tubing. All models are listed under Split Air Conditioners.

The portable air conditioner is placed inside the room and vents the warm air outside via a hose; according to the manufacturer, the portable 12.000-BTU-Geräte are designed for rooms up to 22 or 35 m². The portable split air conditioner from Hantech places the outdoor unit outside—for example, on a balcony or terrace—and, at 39 dB, is significantly quieter inside the room than a monoblock unit.

Which Capacity Is Right for the Room

For smaller rooms up to about 30 m², the next lower class—the 9,000 BTU air conditioner—is often sufficient. For large or open living areas, there’s the 18,000 BTU split air conditioner; for multiple rooms, the multi-split air conditioner is available. The page Professional Installation of Your Air Conditioner explains why we require proof of installation by a certified contractor before shipping a split system.
