Hi this is my first post.
I'm in the process of putting in a Carrier mini-split ac in my home. I've been told from some contractors that a 12,000 btu ac would be perfect while others said I needed a 18,000 btu. My home is 31 x 40 square ft with 5 1/2 rooms. I always thought the bigger the better until the contractor told me that the 12k would be better because it would run constantly rather than an 18,000 which would run and stop.
I'm confused; which is more ideal for my home? I'd also appreciate any feedback re Carrier mini-split systems.
