Short answer
A mini-split is usually the stronger permanent option when the envelope and electrical service are suitable. A dual-hose portable unit can be a lower-commitment choice when a safe, well-sealed exhaust opening is available. A single-hose portable unit often pulls replacement air through garage leaks.
| Question | Portable AC | Mini-split |
|---|---|---|
| Permanent work | Limited | Electrical and refrigerant installation |
| Heat rejection | Hose through exterior opening | Outdoor condenser |
| Floor space | Uses floor area | Wall-mounted indoor unit |
| Low-temperature heating | Model-specific | Model-specific; verify capacity tables |
| Drainage | Tank, evaporation, or drain | Condensate drain required |
