What brands have 6000 BTU condenser units?
Only Midea and Mitsubishi make 6000 BTU condensing units, aka outdoor units. All other brands start at 9000 BTUs.
Did you know? Some outdoor units are quite tall because they have two fans – some are two outdoor units combined into one cabinet. Some 30000 to 48000 BTU condenser units are built as described.
How Much Space Do You Need Between the Mini Split and Ceiling?
4” to 6” for most wall mounted air handlers. Gree specifies 6” while MrCool says 15 cm, which is essentially the same (5.9”).
We’ve heard pro installers say that 3” is enough. For units less than 15,000 BTU, that might be OK. But where headroom isn’t limited, it is better to allow more space for improved airflow. The extra room also makes the unit easier to service.
So, how close can a mini split be to the ceiling?
The best answer is to always check the installation manual to know how much space you need between the mini split and ceiling for the exact model you are using.
