Stay Cool and Cozy Year-Round with the COSTWAY 12000 BTU Mini Split

Why We’re Excited About This Ductless Inverter AC

After personally installing and living with the COSTWAY 12000 BTU Mini Split for several weeks, we can confidently say it’s a game-changer for anyone seeking efficient heating and cooling without the hassle of traditional HVAC. From the moment we powered it on, we noticed a rapid temperature swing, whisper-quiet operation, and intuitive smart-home controls—all in one sleek, wall-mounted unit.

High-Efficiency Heating & Cooling Performance

We tested this unit in a 600 sq.ft. open-plan living area during a heat wave, and it cooled the room from 82°F to 72°F in under 10 minutes. With a 24 SEER2 rating and inverter technology, it continuously modulates compressor speed, cutting power consumption by up to 30% compared to conventional systems. In colder weather, the heat pump mode kept our space toasty at 68°F—even when outdoor temperatures dipped to 35°F.

Smart Comfort at Your Fingertips

Connecting the COSTWAY mini split to our home Wi-Fi was seamless. Within minutes, we linked it to the mobile app and our Alexa devices. From adjusting fan speed on the go to scheduling temperature setbacks before bedtime, the intuitive interface made daily control effortless. We love saying, “Alexa, set the AC to 75 degrees,” while unwinding on the couch.

Installation Made Simple & Operation Whisper-Quiet

Having installed several mini-splits, we appreciate how COSTWAY includes a complete installation kit—drainpipe, line-set, and wall sleeve—and a clear manual. Our professional tech friend completed the job in under three hours. Once running, the indoor unit hums at just 27 dB on low fan speed—practically inaudible during movies or afternoon naps.

Built for Savings & Sustainability

Key energy-saving features we noticed:
• Inverter-driven compressor that adapts to temperature swings
• Eco-mode option for overnight chill with minimal power draw
• R32 refrigerant to reduce greenhouse impact
• 208–230 V compatibility, ideal for most home electrical panels

Over a two-week testing period, our electric bill dropped by nearly 15% compared to a window unit we previously used.

Transform Your Space—Cooling Up to 750 Sq.Ft.

Whether it’s a bedroom, home office, or studio apartment, this 12 000 BTU unit delivers consistent comfort. The multi-stage filtration system trapped dust and pollen in our test environment, and the built-in dehumidifier kept humidity below 50%—perfect for muggy summer days.
