COSTWAY vs TOSOT Mini Split Specs
Efficiency rating
The TOSOT 9,000 BTU model leads with a 20.5 SEER2 rating, while the COSTWAY 18,000 BTU unit offers 20 SEER2. Both use inverter compressors to adjust output smoothly, which saves energy by avoiding constant on-off cycling. The TOSOT achieves a slightly higher efficiency score, meaning it may consume less electricity per unit of cooling or heating provided. However, the COSTWAY includes an ECO mode to further reduce power use. For most users, both ratings indicate high performance, but the TOSOT holds a narrow advantage in pure efficiency metrics.
Coverage area
You need to match the unit to your room size. The COSTWAY 18,000 BTU model is designed for larger spaces up to 1250 square feet. In contrast, the TOSOT 9,000 BTU unit targets smaller rooms, typically under 400 square feet. This is a significant difference in capacity. If you are cooling a large living area or open floor plan, the COSTWAY provides the necessary power. For a bedroom or office, the TOSOT is more appropriately sized. Choosing the wrong capacity leads to poor performance, so your space size is the primary deciding factor here.
Noise level
Quiet operation matters for bedrooms and offices. The TOSOT 9,000 BTU unit operates between 22 dB and 36 dB, making it exceptionally quiet for sleep spaces. The COSTWAY 18,000 BTU model runs as low as 28 dB. While both are whisper-quiet compared to window units, the TOSOT offers a lower minimum decibel level. This makes it slightly better for nurseries or light sleepers. The COSTWAY is still very quiet, but the TOSOT takes the edge for absolute silence in smaller rooms.
Smart control
Both units offer Wi-Fi connectivity and voice control compatibility with Alexa and Google Assistant. The TOSOT uses the GREE+ app for scheduling and remote control, allowing you to pre-cool or pre-heat before you arrive. The COSTWAY also supports app operation and voice commands. Both provide included remotes for local adjustments. The smart features are nearly identical in functionality, with both allowing you to manage settings from your phone. There is no significant difference in connectivity options between the two brands.
Voltage compatibility
Installation requirements depend on your home’s electrical setup. Both the COSTWAY 18,000 BTU and the TOSOT 9,000 BTU models operate on 230V circuits. The COSTWAY also lists 208V compatibility, which is common in some commercial or multi-family buildings. The TOSOT data confirms 230V operation. Both require professional installation and proper vacuuming. Since both use standard high-voltage connections, neither has a clear advantage for typical residential 230V outlets. You will need a dedicated circuit for either unit.
Included accessories
Installation costs can vary based on what is in the box. The TOSOT 9,000 BTU unit comes with a 16 ft. copper line set and essential installation accessories, which reduces the need for extra parts purchases. The COSTWAY 18,000 BTU data does not explicitly list included line sets or installation hardware. This means you might need to buy the line set separately for the COSTWAY. For buyers looking for a more complete out-of-the-box experience, the TOSOT provides a clear advantage with its included copper tubing.
Which Mini Split Fits Your Needs
