COSTWAY vs Tehanld Mini Split Specs
Cooling capacity
Edge: COSTWAY 24000 BTU 230V Mini Split
The COSTWAY 24000 BTU 230V Mini Split delivers twice the cooling power of the Tehanld 12000 BTU Mini Split. This higher capacity makes the COSTWAY unit better suited for larger rooms or open-concept living areas. The Tehanld model is rated for spaces up to 750 square feet, which is ideal for smaller bedrooms or offices. If you need to cool a large volume of air quickly, the COSTWAY 24000 BTU unit provides that extra capacity. The Tehanld 12000 BTU unit is sufficient for standard-sized rooms where extreme cooling is not required. Your choice depends on the square footage of the space you intend to condition. Higher BTU units generally consume more energy, so consider your room size carefully before deciding.
Energy efficiency
Edge: COSTWAY 24000 BTU 230V Mini Split
The COSTWAY 24000 BTU 230V Mini Split has a SEER2 rating of 18.5. The Tehanld 12000 BTU Mini Split has a SEER2 rating of 17. A higher SEER2 number indicates better energy efficiency during cooling operation. This means the COSTWAY unit converts more electricity into cooling output compared to the Tehanld model. For users concerned about long-term electricity costs, the higher efficiency of the COSTWAY unit is a practical advantage. Both units use inverter technology to adjust compressor speed, which helps maintain steady temperatures. However, the specific SEER2 rating gives the COSTWAY unit a clear edge in efficiency metrics. You should verify if the higher efficiency offsets the higher power draw of the larger unit.
Electrical requirements
Edge: Tehanld 12000 BTU Mini Split
The COSTWAY 24000 BTU 230V Mini Split requires a 208-230V electrical circuit. The Tehanld 12000 BTU Mini Split is available in a 115V configuration. If your home only has standard 115V outlets, the Tehanld unit is easier to install without upgrading your electrical panel. The COSTWAY unit needs a dedicated 230V line, which often requires professional installation by a licensed HVAC technician. This is a significant factor for renters or homeowners who cannot modify their electrical systems. The Tehanld 115V model offers greater compatibility with existing residential wiring. If you have the necessary 230V infrastructure, the COSTWAY unit is viable. Otherwise, the Tehanld 115V option is the more practical choice for standard homes.
Operating modes
Edge: COSTWAY 24000 BTU 230V Mini Split
Both units offer five flexible operating modes: Cool, Heat, Auto, Fan, and Dry. This similarity means you get the same core functionality for year-round comfort from either brand. The COSTWAY 24000 BTU 230V Mini Split also includes specific modes like Sleep, ECO, iFEEL, and Turbo. The Tehanld 12000 BTU Mini Split includes Sleep, Quiet, Turbo, and ECO modes. The iFEEL feature on the COSTWAY unit allows for personalized temperature sensing based on the remote location. Both units provide four adjustable fan speeds to control airflow intensity. The presence of iFEEL on the COSTWAY model adds a layer of customization that the Tehanld unit lacks. For most users, the standard modes are sufficient, but the extra features on the COSTWAY unit provide more control.
Refrigerant type
Edge: Tehanld 12000 BTU Mini Split
The Tehanld 12000 BTU Mini Split uses R32 refrigerant, which is noted for being eco-friendly and energy-efficient. The COSTWAY 24000 BTU 230V Mini Split specifies a GWP of 675 for its refrigerant but does not explicitly name the type. R32 refrigerant generally has a lower global warming potential than older alternatives like R410A. If environmental impact is a priority for you, the Tehanld unit clearly states its use of R32. The COSTWAY unit meets AHRI certification standards, ensuring reliable performance. However, the lack of explicit refrigerant naming on the COSTWAY side makes direct comparison difficult. You may need to check the unit label for the specific refrigerant type on the COSTWAY model. For now, the Tehanld unit offers transparency regarding its eco-friendly design.
