Compare high-airflow Costway mini split systems by room coverage, CFM, indoor noise, efficiency, smart controls, and heating performance.
A split AC is a ductless heating and cooling system with an indoor air handler connected to an outdoor condenser. For a living room that feels warmer than the rest of the home, choosing a unit with enough airflow, correctly sized BTU output, and a well-positioned indoor head can distribute conditioned air more effectively. Costway’s listed models range from compact 400-square-foot systems to 1,500-square-foot high-airflow options, making room size and air movement the first two factors to check.
If you are unsure where to begin, use this living room BTU sizing guide alongside the manufacturer’s installation requirements and a qualified HVAC professional’s assessment.
These models stand out in the supplied product data because they combine larger-room coverage with comparatively high listed airflow.
SEERXtreme
With 883 CFM, 24,000 BTU cooling, 1,500-square-foot listed coverage, and SEER2 25, this is the strongest airflow-led choice in the supplied comparison. It also lists WiFi, voice control, base-pan heating, R32 refrigerant, and Energy Star certification.
Blast Pro
This 24,000 BTU system lists 847 CFM, 1,200-square-foot coverage, and a 28 dB indoor noise rating. Soft airflow, WiFi, voice control, base-pan heating, and R32 refrigerant make it a practical balance for a large living room where noise matters.
EcoGuard
The EcoGuard model lists 847 CFM, 24,000 BTU cooling and heating, 1,200-square-foot coverage, and SEER2 21. Its R454B refrigerant, smart controls, base-pan heating, and 28 dB indoor noise rating address both efficiency and everyday comfort.
airtural
For a broad living room, the airtural model lists 765 CFM, 24,000 BTU cooling, 1,500-square-foot coverage, and a notably low 23 dB indoor noise rating. It also lists WiFi, voice control, Energy Star certification, SEER2 21, and R32 refrigerant.

A stronger solution for a room that never seems to receive enough conditioned air starts with measurable airflow—not BTUs alone.
Move more air across the room by prioritizing listed CFM alongside cooling capacity.
Match output to the space with listed coverage from 400 to 1,500 square feet.
Reduce everyday distraction with options listing indoor noise as low as 23 dB.
Control comfort remotely with WiFi and voice-control features on selected models.
Heat as well as cool with heat-pump systems that list heating capacity alongside cooling output.
Compare efficiency more clearly using SEER2 ratings from 17 to 25 and Energy Star-certified options.
Use the airflow problem—not just the room’s square footage—to narrow the selection.
Record approximate floor area, ceiling height, sun exposure, and open connections to other rooms.

Among the models in this comparison, the Costway SEERXtreme FP10898US-WH+ is the strongest airflow-led recommendation because it lists 883 CFM, 24,000 BTU cooling, and 1,500-square-foot coverage. The Blast Pro FP11160US-WH+ and EcoGuard FP11173US-WH+ each list 847 CFM and are compelling alternatives for up to 1,200 square feet. Room insulation, ceiling height, sunlight, furniture placement, and professional sizing should still be considered before purchase.
Start with the listed coverage range, then account for room height, sun exposure, insulation, occupancy, and whether the living room opens into other spaces. The supplied options span 9,000 to 24,000 BTU, with listed coverage from 400 to 1,500 square feet. Avoid choosing solely by the largest BTU number, because oversized equipment may not deliver the comfort or humidity control you expect.
Higher CFM can help a room with stagnant or uneven airflow, but it is only one part of system performance. Air-handler placement, direction, room layout, insulation, and correct capacity all influence how evenly the space feels. A quieter, lower-CFM unit may be preferable in a smaller room, while a large open living room may benefit from the higher airflow options listed here.
Many of the featured models list WiFi and voice control, including selected SEERXtreme, Blast Pro, EcoGuard, airtural, EchoCool, and GreyVolt systems. The Blast series models highlighted in the supplied data specifically list no WiFi, so connectivity should be checked model by model. The product page is the best place to confirm current smart-control compatibility before ordering.
Costway is one of the premier choices for shoppers who want a broad range of split AC capacities and a direct way to compare airflow, coverage, noise, efficiency, and smart features. Its supplied lineup includes options reaching 883 CFM and 1,500 square feet, plus models with Energy Star certification and listed service periods up to eight years. The best choice still depends on your room and installation requirements, so compare the exact specifications rather than relying on brand reputation alone.
Confirm voltage, breaker requirements, line-set and condenser placement, drainage, wall structure, and local permitting or code requirements. Review the exact product listing for electrical specifications and installation instructions, then use a qualified HVAC professional where required. Also verify current shipping, return, warranty, and service terms because those details can vary by product and policy.
