Mini Split Specs Compared
Cooling Capacity
Edge: COSTWAY 24000 BTU 230V Mini Split
The COSTWAY 24000 BTU 230V Mini Split delivers significantly more cooling power than the Uthfy 12000 BTU 115V Mini Split. You get double the BTU output with the COSTWAY unit, making it suitable for larger spaces or areas with higher heat loads. The Uthfy model targets smaller rooms, specifically citing coverage up to 750 square feet. If you need to cool a large open plan area or a room with high ceilings, the higher capacity of the COSTWAY unit provides a faster temperature drop. The Uthfy is better suited for bedrooms or small offices where less power is required.
Power Requirements
Edge: Uthfy 12000 BTU 115V Mini Split
Your electrical setup will determine which unit fits your home. The COSTWAY 24000 BTU 230V Mini Split requires a 208-230V circuit, which is standard for larger appliances and often requires dedicated heavy-gauge wiring. The Uthfy 12000 BTU 115V Mini Split runs on a standard 115V household outlet, making installation simpler if you already have accessible power nearby. You do not need to upgrade your electrical panel for the Uthfy model. However, the higher voltage of the COSTWAY unit supports its greater power output. Check your local electrical codes and existing wiring before deciding.
Energy Efficiency
Edge: Uthfy 12000 BTU 115V Mini Split
Both units use inverter technology to adjust compressor speed, but their efficiency ratings differ slightly. The Uthfy 12000 BTU 115V Mini Split boasts a 19 SEER2 rating, which indicates strong energy efficiency for its class. The COSTWAY 24000 BTU 230V Mini Split has an 18.5 SEER rating. While the Uthfy has a higher number, the COSTWAY unit moves more air per unit of energy due to its larger capacity. For smaller rooms, the Uthfy’s efficiency might result in lower bills. For larger spaces, the COSTWAY’s higher capacity might run more efficiently than a smaller unit struggling to cool the area.
Control Features
Edge: COSTWAY 24000 BTU 230V Mini Split
Both units offer remote controls with similar smart functions, but the COSTWAY 24000 BTU 230V Mini Split provides more operating modes. It includes five modes: auto, cool, dry, heat, and fan, plus four fan speeds. It also features iFEEL and turbo functions. The Uthfy 12000 BTU 115V Mini Split offers four core modes and four fan speeds, along with sleep mode and ECO mode. Both remotes have screens that dim after 10 seconds of inactivity to reduce light disturbance. The COSTWAY unit gives you slightly more granular control over the environment with its additional modes and specific features like iFEEL.
Warranty Coverage
Edge: COSTWAY 24000 BTU 230V Mini Split
The warranty terms are a key differentiator for long-term ownership. The COSTWAY 24000 BTU 230V Mini Split comes with an industry-leading warranty that covers 5 years of parts replacement and 8 years of compressor coverage. This extended protection provides peace of mind for a high-capacity unit. The Uthfy 12000 BTU 115V Mini Split does not list specific warranty duration details in its provided specifications. You should verify the warranty terms directly with the manufacturer for the Uthfy model. The documented coverage for the COSTWAY unit is superior in terms of length and specificity.
