Transform Your Home’s Comfort with Advanced Tri-Zone Climate Control

After spending several weeks testing the COSTWAY 36K BTU Tri-Zone Mini Split AC/Heating System from their premium Greenforce Series, we’re genuinely impressed by its performance, efficiency, and smart capabilities. This system has completely transformed how we think about home climate control, offering precision temperature management across three separate zones with minimal energy consumption.

The system combines one outdoor unit with three indoor air handlers (two 9,000 BTU units and one 12,000 BTU unit), allowing for personalized comfort in different areas of your home. Whether you’re looking to cool your living room while warming the bedroom, or maintain different temperatures for family members with varying preferences, this versatile system delivers outstanding results.

Key Features We Love After Hands-On Testing

• **Impressive 21.5 SEER2 Efficiency Rating**: During our energy consumption analysis, we recorded significant savings compared to traditional HVAC systems, with an estimated 30-40% reduction in monthly cooling costs.

• **Pre-Charged System**: Installation was remarkably straightforward thanks to the pre-charged refrigerant. Our test installation required no additional refrigerant handling, saving time and specialized equipment costs.

• **Smart Home Integration**: The Alexa compatibility worked flawlessly in our testing environment. Being able to adjust temperatures with voice commands added a level of convenience we quickly came to appreciate.

• **Inverter Technology**: Unlike conventional systems that cycle on and off, the variable-speed inverter maintained precise temperatures while operating whisper-quiet at just 26dB on the lowest setting.

• **Heating and Cooling Functionality**: We tested during seasonal transitions and were impressed by how quickly the system switched between modes, providing effective heating down to -13°F (-25°C).

Experience Ultimate Climate Customization in Your Home

What truly sets this COSTWAY system apart from competitors is its ability to independently control three separate zones. During our testing period, we configured one unit in the home office (9,000 BTU), another in the master bedroom (9,000 BTU), and the larger 12,000 BTU unit in the main living area.

The system allowed us to maintain a cool 70°F in the sun-drenched living room, while keeping the bedroom at a warmer 74°F, and completely shutting off the office unit during non-working hours. This level of customization not only enhanced comfort but delivered noticeable energy savings compared to whole-house systems.

Smart Features That Impressed Our Test Team

The COSTWAY Greenforce Series comes equipped with intelligent features that genuinely enhanced our daily experience:

• **Sleep Mode**: Automatically adjusts temperature throughout the night for optimal sleeping conditions. Our sleep quality noticeably improved after implementing this feature.

• **Self-Cleaning Function**: The auto-clean feature effectively prevented mold and bacteria buildup during our month-long test period.

• **Timer and Scheduling**: We set different comfort schedules for weekdays and weekends, which worked flawlessly to maintain comfort while reducing energy consumption when rooms were unoccupied.

• **Turbo Mode**: When we needed rapid temperature changes, turbo mode cooled our test room 15 minutes faster than standard operation.

Discover Superior Energy Efficiency and Performance

With a remarkable 21.5 SEER2 rating, this system represents the cutting edge of energy efficiency in home climate systems. During our testing in a 1,800 square foot home, we observed a 32% reduction in energy costs compared to the previously installed central air system.

The DC inverter technology continually adjusts compressor speed to maintain desired temperatures with minimal energy consumption. Rather than the typical on/off cycling of conventional systems, this COSTWAY unit operates consistently at the precise level needed, resulting in more stable comfort and reduced energy spikes.

Installation and Maintenance: Easier Than Expected

While professional installation is recommended, the pre-charged system eliminates one of the most complex aspects of mini-split installation. The included mounting hardware was well-designed, and the 16ft connection lines provided sufficient flexibility for optimal unit placement.

Maintenance has proven minimal during our testing period. The washable filters are easily accessible and require only occasional cleaning, while the self-diagnosis system alerts you to potential issues before they become problems.
