FAQ: Split Systems What is the best place to install a wall mount air conditioner?
A wall mount indoor unit (also known as a high-wall split system) is best positioned high on the wall with easy access to drainage. There are other installation options you can discuss with a Fujitsu General air conditioning specialist.
A ceiling cassette air conditioner should be installed in the center of the ceiling so that cool or warm air can circulate evenly in all 4 directions. We recommend that you not install a ceiling cassette air conditioner in the corner of the ceiling or close to the wall unless that is part of the interior design scheme.
