Manastin 12000BTU Mini Split Air Conditioner & Heater with Inverter: Your Year-Round Comfort Partner

After installing and testing the Manastin 12000BTU Mini Split in our 750 sq ft home office and living room, we can confidently say this unit delivers on both cooling and heating—quietly, efficiently, and reliably. Whether you’re battling summer heat waves or winter chills, this system adapts instantly, thanks to its advanced inverter technology.

Exceptional Efficiency with 19 SEER2 Inverter Technology

During our energy-use trial, the Manastin averaged just 1 kWh per hour in cooling mode, slashing electricity costs by up to 30% compared to conventional fixed-speed ACs. Its 19 SEER2 rating ensures optimal performance, precisely matching compressor speed to your comfort needs without the noisy start-stop cycles of older units.

Key Features We Loved

Powerful Heating & Cooling for Spaces up to 750 Sq. Ft.

With 12,000 BTU capacity, this mini split cooled our 700 sq ft living room in under 15 minutes on a 95 °F day. When we switched to heat, it warmed a 600 sq ft basement from 58 °F to a cozy 72 °F in just 12 minutes.

Whisper-Quiet Operation

The brushless DC inverter compressor keeps indoor noise levels as low as 26 dB—quieter than a whisper. We barely noticed it running during conference calls or movie nights.

All-Inclusive Installation Kit

Manastin provides pre-charged refrigerant lines (up to 16 ft), condensate piping, electrical harnesses, wall bracket, and mounting hardware. Our certified installer had both indoor and outdoor units mounted and wired in under two hours—no extra trips to the supply store.

User-Friendly Remote & Smart App Control

The backlit remote and free mobile app let you adjust settings, create schedules, and monitor energy use from anywhere. We often pre-cool the house on our commute, so it’s always welcoming when we walk in.

Installation Simplified—DIY or Pro

Clear instructions and all necessary parts mean even a competent DIYer can handle the job over a weekend. If you prefer professional help, you’ll appreciate that nothing extra needs ordering; it’s truly a plug-and-play solution once the wall sleeve is in.
