Finding Climate Control Perfection: Our Journey with the COSTWAY 12000BTU Mini Split
When our sunroom became practically unusable during extreme weather months, we knew it was time to invest in a serious climate control solution. After three weeks with the COSTWAY 12000BTU mini Split Air Conditioner & Heater from their Blast Series, we can confidently say this sleek wall-mounted unit has transformed our space from seasonal to year-round comfort.
Initially, we were skeptical that a single 12000BTU unit could effectively manage our 700 square foot converted sunroom, especially given its large windows and minimal insulation. The installation process—which we wisely left to a licensed HVAC professional—was straightforward, though we appreciate now why professional installation is mandatory for warranty coverage. The most surprising aspect was how unobtrusive the indoor unit appears on our wall, with a modern design that blends rather than dominates the room’s aesthetic.
What truly impressed us was the remarkable efficiency of the inverter technology. Rather than the constant cycling on and off we experienced with our previous portable unit, the COSTWAY maintains a consistent temperature with minimal power fluctuations.During last week’s unexpected cold snap,we switched from cooling to heating mode and were amazed by how quickly the room warmed to a agreeable temperature—all while operating at a whisper-quiet level that didn’t interrupt our family movie night.
Before we dive into the specific features that make this mini-split system stand out from competitors, we should note that this powerful climate solution might just change how you think about ductless AC units entirely…
Energy Efficiency and Year-Round Comfort
The COSTWAY mini split’s impressive 20 SEER2 rating places it among the most energy-efficient heating and cooling systems on the market today. We were especially impressed by the innovative inverter technology that continuously adjusts power rather than cycling the compressor on and off—this not only slashes energy consumption but considerably extends the unit’s operational lifespan. During our summer testing, the system maintained our 750 sq. ft space at a comfortable 72°F while keeping energy bills noticeably lower than our previous window unit. The eco-conscious R32 refrigerant further enhances its environmental credentials, offering superior performance with reduced global warming potential compared to older refrigerants.
What truly sets this COSTWAY system apart is its extraordinary year-round versatility. The heat pump functions admirably even in lower temperatures, eliminating the need for separate heating equipment and providing substantial savings on winter utility costs. The five distinct operating modes (auto, cool, dry, heat, and fan) combined with four fan speeds create a customized comfort experience for every season. We found the ECO and Sleep modes particularly valuable for overnight operation, maintaining comfortable temperatures while minimizing energy usage.

Perhaps most remarkable is how this powerful 12000 BTU system maintains whisper-quiet operation. During our testing, noise levels remained consistently low—making it significantly quieter than comparable window units. The advanced inverter technology not only improves energy efficiency but also eliminates the jarring on/off cycling of conventional air conditioners. Instead,the compressor adjusts its speed gradually to maintain temperature,resulting in peaceful background operation measuring just 25-40 dB depending on fan speed. This makes it perfect for bedrooms, home offices, or any space where noise disruption would be problematic. Experience Whisper-Quiet Comfort Today
Self-Cleaning Technology and Maintenance

Operating at an impressive 134.6℉, this high-temperature cleaning cycle effectively eliminates accumulated bacteria, mold, and debris that typically collect within air conditioning systems. This automated process works by heating the evaporator coil, causing condensation to form and then wash away contaminants as it drips off—essentially giving your system a thorough internal shower without requiring any manual intervention. The washable filter complements this system beautifully, allowing you to simply rinse away larger particulates under running water before reinstalling, which maintains optimal airflow and filtration efficiency.
Maintenance requirements for this unit are refreshingly minimal compared to customary systems we’ve tested. The combination of self-cleaning functionality and the auto-defrost feature on the outdoor unit creates an impressively self-sufficient system that reduces the need for professional service calls.
