Quiet enough for the bedroom?
Noise level matters in the bedroom. With a split-system air conditioner, only the indoor unit is located in the room; the spec sheets list a sound pressure level of 19 to 22 dB on the quietest setting, while the outdoor unit operates outside. The portable units have both the compressor and fan inside the room; the two portable 9.000-BTU models list noise levels of 51 and 53 dB. If you want to cool your room at night, you’re better off with the split-system set; if you need a solution that doesn’t require installation, the portable unit is the better choice.
What Sets the Designs Apart
According to the catalog, the 9,000-BTU split systems cool at 2.6 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 lines; all models are listed under Split Air Conditioners. According to the manufacturer, the portable units are designed for rooms up to 26 m² and vent warm air outside via a hose; see Portable Air Conditioners for more information. For larger rooms, there is the 12,000 BTU air conditioner.
