By oversizing them, you can lose that advantage completely. That 6,000 BTU per hour mini-split in a room with 1,500 BTU per hour of cooling load doesn't act at all like it has variable capacity because it's always running at the lowest capacity. So, yes, you absolutely can oversize a mini-split.27 may 2021
Is it better to oversize or undersize a heat pump?
Overall, an undersized heat pump is better than an oversized one. An undersized heat pump will take longer to change the temperature. But, the unit won't be as loud and will last longer. An oversized heat pump will turn on and off more frequently, which will use more electricity.15 feb 2021

Can you over size a mini split?
So, yes, you absolutely can oversize a mini-split. And when you do, you end up with some of the same problems you get from oversizing conventional systems: poor humidity control, short cycling, and wasted money.27 may 2021
Even though it takes a powerful system – especially in a large home – a ductless mini split is up to the task. With the right size system in place, it's capable of cooling an entire house, from the basement all the way up to the attic.11 jun 2020
How many rooms can a mini split cool?
Both can be used to cool a single room without ductwork. But a mini-split can add more evaporator units (up to 4) to one condenser unit. So technically it can cool up to 4 rooms. Mini-splits are also much more energy efficient than window units and last longer, too.11 jul 2014
