- Installation Requirements: Mini splits require wall mounting and some outdoor unit clearance. Consider whether installation kits are included to simplify the setup.
- Heating Performance: If you need year-round comfort, choose units with effective heat pumps that operate at low outdoor temperatures.
- Smart Features and Controls: Wifi and voice assistant compatibility enhance convenience by allowing remote control and scheduling.
- Noise Levels: Lower noise operation is important for garages attached to living spaces.
- Maintenance and Warranty: Look for units offering self-diagnosis, defrosting, and cleaning modes to ease upkeep.
By balancing these factors, you can select a mini split system that maintains your garage’s climate efficiently and comfortably throughout the year.
