I am researching to purchase a multi zone mini split system.
I am going to purchase a 9 + 12 two zone system.
The place I am looking at is selling a 9 + 12 with a 20,000 BTU outside condenser.
Does the condenser unit BTU have to equal the indoor units? Meaning, shouldn't the outdoor unit be 21,000?
By the way, the also sell a 12 + 12 with the same 20,000 outdoor unit.
Any help is greatly appreciated before spending a lot of money.
PS. this unit is heat and cool
