COSTWAY 30k Dual 2 Zone Mini Split Air Conditioner Review: 23 SEER2, 18k BTU + 24k BTU, Wifi-Enabled Heat Pump

After installing and testing the COSTWAY 30k Dual Zone Mini Split in our own home, we’re genuinely impressed by how it balances powerful performance, energy savings, and modern convenience. Whether you need targeted cooling in a living room and bedroom, or efficient heating throughout chillier months, this ductless AC heat pump delivers consistent comfort without skyrocketing your energy bill.

Discover Exceptional Efficiency with 23 SEER2 Technology

We clocked an impressive 23 SEER2 rating on our energy monitor—well above most standard mini splits. That translates to up to 40% lower electricity usage compared to older models. During peak summer days, the outdoor compressor ran smoothly without overworking, and the indoor units maintained set temperatures within ±0.5 °F.

Customize Two Zones: 18,000 BTU + 24,000 BTU

In our trial, we placed the 18k BTU head in a 300 sq ft home office and the 24k BTU head in a 450 sq ft living area. Each unit responded independently, letting us set 72 °F in the office for focused productivity, while keeping the living room cozy at 75 °F. Zone flexibility like this is a game-changer for energy savings and personal comfort.

Control from Anywhere with Built-In Wifi

One of our favorite features: seamless Wifi scheduling via COSTWAY’s app and compatibility with Alexa and Google Home. We toggled between “Heat” and “Cool” modes while away on vacation, returning to perfectly conditioned rooms. App setup took under five minutes—no extra hubs required.

Whisper-Quiet Operation & Sleek Design

Running at just 22 dB on low fan speed, even our lightest sleepers barely noticed it at night. The indoor units sport a slim profile and unobtrusive white finish that complements any décor. During our movie nights, the audio system stayed front and center—no background hum to compete with.

Full Installation Kit Makes Setup Straightforward

COSTWAY includes everything you need: two indoor heads, one outdoor compressor, refrigerant lines, drain pump, remote controls, mounting brackets, and a 16 ft interconnecting cable. We recommend a certified HVAC technician for best results, but all components were clearly labeled, speeding up the professional install.

Standout Benefits We Noticed Firsthand

• Rapid temperature recovery: cooled our 450 sq ft room from 78 °F to 72 °F in under 10 minutes on high.
• Energy Star–certified, saving us approximately $250–$300 annually versus our old window units.
• Integrated defrost cycle for reliable heating down to –5 °F outdoor temps.
• Auto-swing louvers ensure even air distribution—no hot or cold spots.
• Intuitive LED touch display and magnetically attaching filter for hassle-free maintenance.
