Short Cycling

Short cycling is when your system turns on, runs for a minute or two, shuts off, then starts up again almost immediately. It's hard on the compressor and means the system never runs long enough to actually control humidity or maintain a stable temperature. The most common causes are an oversized unit (too much capacity for the space), low refrigerant, a dirty coil, or an electrical issue. An oversized mini split is a surprisingly common problem — bigger isn't always better. A load calculation done up front is what prevents it.
