- Energy efficiency: Look for SEER2 ratings and HSPF2 for heating. Higher ratings reduce long-term operating costs.
- Climate compatibility: Check operating temperature ranges for both cooling and heating to match your local climate.
- Smart features: WiFi, Alexa compatibility, and mobile app control add convenience and potential energy savings via scheduling.
- Installation requirements: Verify electrical service (voltage), space for outdoor units, and line-set lengths to avoid performance drops.
- Noise considerations: Note decibel levels in indoor units and the impact on bedrooms or study areas.
- Maintenance and durability: Look for features like auto defrost, dehumidification modes, and recommended service intervals.
Frequently Asked Questions
- What is a dual zone mini split system?
