Buying Guide
- Room size and layout: Match BTU capacity to space, taking into account ceiling height and heat sources. Bigger rooms may benefit from higher SEER2 units with better air distribution.
- Energy efficiency: Look for SEER2 ratings and inverter technology. Higher SEER2 can lower operating costs over time but may come with more complex installation.
- Operating modes: Common needs include cooling, heating, dehumidification, and fan-only. Consider ECO or Sleep modes for overnight or busy daytime schedules.
- Noise levels: For bedrooms or nurseries, prioritize units with low dB ratings in Sleep or mute modes.
- Smart features: Alexa compatibility or remote app control can add convenience for daily use; assess whether you want voice control or straightforward remote operation.
- Installation considerations: Pre-charged condensers simplify setup but verify your electrical requirements (voltage, circuit capacity) and whether professional installation is recommended in your area.
- Maintenance and filters: Self-cleaning and easy-access filters reduce upkeep. Consider units with auto-defrost for winter operation in colder climates.
