- Noise Levels: If the unit will be placed in a bedroom or quiet area, choose models with low decibel ratings (typically below 40 dB).
- Smart Controls and Connectivity: WiFi-enabled units offer convenient remote operation and integration with home assistants like Alexa or Google Assistant.
- Additional Features: Modes such as heating, drying, and fan-only provide year-round versatility. Timer functions and adjustable louvers enhance user comfort.
- Accessory Compatibility: For efficient condensate management, pairing your mini split with a silent condensate pump can prevent water issues and extend system longevity.
- Power Source: Consider the electrical supply available; 115V units are more common for residential use, while 12V systems suit mobile or vehicular applications.
Choosing the right mini split depends on balancing your space requirements, desired features, and installation preferences to enjoy efficient, customizable comfort throughout the year.
