COSTWAY 18K BTU Dual 2-Zone Mini Split AC/Heating System Hands-On Review

Discover Year-Round Comfort—Here’s What We Found

We installed the COSTWAY Greenforce Series dual-zone inverter system in two adjoining rooms and were honestly impressed from the moment we flipped the switch. Whether delivering a precise 65°F on a sweltering summer afternoon or gently warming your living space to 72°F on a crisp fall morning, this 22 SEER2 unit blends whisper-quiet operation with rock-solid performance.

Easy Installation and Setup

After unpacking the pre-charged outdoor compressor and two sleek wall-mounted indoor units, our HVAC installer had everything mounted and wired in under three hours. The pre-charged refrigerant lines meant no extra field charging—saving time and avoiding mess. The included mounting bracket, wall sleeves, and clear instructions made the process smoother than many ductless systems we’ve tested.

Whisper-Quiet Operation—Perfect for Bedrooms and Offices

At just 23 dB on low, the indoor units are quieter than a soft whisper. We ran the AC at 30% fan speed overnight in a home office and woke up to a perfectly cooled, undisturbed sleep. Even at maximum output, the noise level never climbed above 48 dB—a disturbance you’ll barely notice.

Energy Savings You Can See on Your Bill

With a 22 SEER2 rating, the Greenforce Series outperforms many standard mini-splits. Over a 90-day cooling season, our energy monitoring showed a 25% reduction in electricity usage compared to our old window units. Heating mode is equally efficient, thanks to the inverter compressor that precisely adjusts power based on demand.

Smart Home Integration—Control with Alexa or App

We linked the system to our home’s Alexa network in under two minutes. A simple “Alexa, set living room to 70 degrees” had the indoor unit ramping up instantly. The companion app lets you program daily schedules, monitor real-time power consumption, and even switch between Eco, Turbo, and Quiet modes from anywhere.

Built for Longevity

COSTWAY’s Greenforce refrigerant is eco-friendly and R32-based, reducing greenhouse impact. The durable galvanized-steel outdoor unit casing resisted rust even after two weeks of heavy rain testing. Inside, the copper coils and auto-clean function keep mold and dust build-up at bay.
