Buying Guide: Ceiling Cassette Mini Splits With Branch Duct

What to consider when choosing a ceiling cassette with branch duct:

• Room size and zoning: Determine how many zones you need. Dual-zone or triple-zone systems offer independent control but require more complex installation.

• Energy efficiency: Check SEER2 and EER values; higher numbers indicate better long-term energy savings.
• Smart integration: Consider whether a control app or voice assistant compatibility fits your workflow.
• Installation kit and line sets: Ensure included kit length matches your ceiling height and room dimensions; pre-charged options simplify setup.
• Maintenance: Look for accessible service ports, leak sensors, and filter access for easier upkeep.
