Buying Guide: Key Considerations For 28,000 BTU Heat-Capable Systems
- Zone configuration: Do you need three zones or two zones? More zones offer better per-room control but may require more indoor units.
- Outdoor unit capacity: Ensure the outdoor condenser supports the total BTU across zones and that line sets fit your space.
- Energy efficiency: Look for SEER2 and HSPF ratings to estimate operating costs, especially in warm climates.
- Controls and smart features: WiFi, app control, and voice assistants can simplify daily use and scheduling.
- Installation considerations: Professional installation is often necessary for refrigerant charging, wiring, and correct mounting. Check for pre-charged convenience and required clearances.
- Ambient performance: Some units advertise operations in very low or extremely high temperatures; verify that heating performance matches your winter needs.
- Noise levels: Consider indoor unit noise when selecting multiple zones, especially in bedrooms or study areas.
