Buying Guide
- How big should your mini split be? Match BTU to room size and insulation. Most 12,000 BTU units cover up to 750 sq.ft.; larger areas may require 18k-24k BTU.
- SEER2 and energy efficiency matter. Higher SEER2 saves more energy over time, especially with frequent use or year-round cooling/heating.
- Voltage considerations. Many units run on 115V, but some 24,000 BTU models require 208-230V. Verify electrical capacity and panel space before installation.
- DIY vs professional installation. Some models advertise DIY-friendly setup, but indoor-outdoor connections and refrigerant handling may still benefit from a licensed technician.
- Noise levels. For bedrooms or home offices, look for units with low decibels in sleep or mute mode.
- Smart controls. If you value app control or voice assistant integration, choose models with WiFi, app compatibility, or Alexa/Google Assistant support.
- Maintenance and filtration. Self-cleaning or easy-access panels reduce maintenance time and keep performance high.
