Buying Guide: Key Considerations
What space will you air condition? Measure the room and compare it to each unit’s recommended square footage to avoid under‑ or over‑conditioning the area.
What energy efficiency do you need? Look for SEER2 ratings and inverter technology. Higher SEER2 typically means lower operating costs over time.
Do you want smart features? Wifi or app control adds convenience but may require network setup and occasional updates.
How important is noise level? Bedrooms and nurseries benefit from units with low dB ratings in sleep or mute modes.
What about installation and kit contents? Some models come with pre‑charged condensers and installation kits; verify compatibility with your space and existing wiring.
