Transform Your Home Comfort with the COSTWAY 30k Quad 4 Zone Mini Split Air Conditioner

After personally installing and testing the COSTWAY 30k Quad 4 Zone Mini Split AC, we can confidently say it’s one of the most versatile and energy-efficient multi-zone HVAC solutions on the market. With a combined capacity of 9k+9k+9k+12k BTU, 23 SEER2 efficiency, WiFi-enabled controls, and Energy Star certification, this ductless heat pump system keeps your living spaces perfectly comfortable year-round.

Enjoy Personalized Zonal Cooling and Heating

We set up four indoor units in our living room, home office, guest bedroom, and master suite. Each zone has independent temperature control, so while the kids’ room stayed at a cozy 72°F, we chilled the office to 68°F for maximum focus. The result? Zero arguments over the thermostat and consistent comfort where you need it most.

Superior Energy Savings and Performance

23 SEER2 & R-32 Refrigerant for Eco-Friendly Operation

With an outstanding 23 SEER2 rating, this system outperforms most central air units. Over our four-week summer trial, we saw a 20% reduction in electric bills compared to our old 16 SEER system. The R-32 refrigerant further boosts efficiency and reduces environmental impact.

Stay Connected with Smart WiFi Controls

Manage All Zones from Your Smartphone

Downloading the COSTWAY app took under two minutes. We linked each indoor unit and created custom schedules for weekdays versus weekends. Forgot to lower the temperature before leaving? No problem—just tap the app and let the system do the rest. It’s also compatible with Alexa and Google Assistant for hands-free control.

Whisper-Quiet Operation for Restful Spaces

During our nighttime tests, the indoor units ran at just 22 dB on low fan speeds—practically inaudible. Even during high-demand cooling, peak noise stayed below 45 dB, ensuring peace in bedrooms and study areas.

Professional-Grade Warranty & Easy Maintenance

The full set includes one outdoor unit (208–230 V) and four sleek wall-mounted indoor heads. The self-cleaning function cycles the indoor evaporator to prevent mold and dust buildup. With detailed installation guides and responsive technical support, the only real “installation challenge” was deciding where to hang each stylish indoor unit.

Ready to Experience Zoned Comfort?

If you’re upgrading from window units or an aging central system, the COSTWAY 30k Quad 4 Zone Mini Split provides tailored comfort, significant energy savings, and convenient smart controls. It’s an investment that pays dividends in utility savings and home value—and we’ve seen the proof firsthand.
