Buying Guide

What should you consider when choosing an air cooled split unit?

• Room size and BTU: Match BTU to the space. Oversized units waste energy; undersized units struggle to maintain comfort.
• Seer2 rating and inverter technology: Higher SEER2 means better long-term energy savings. Inverter tech smooths operation and reduces on/off cycling.
• Climate range: Check operating temperature range (some units work down to 5°F or up to 122°F). Choose based on your local climate.
• Noise level: For bedrooms or nurseries, prioritize units with quiet modes and lower dB ratings.
• Smart features: App control, remote access, and voice assistants add convenience but require reliable Wi-Fi.
• Installation considerations: Wall-mounted vs. ceiling or floor placement; some brands ship in two packages or require professional installation.
• Maintenance: Self-cleaning features can reduce buildup; check filter access and cleaning steps.
