Rellytech 12000 BTU Mini Split AC/Heating System – 19 SEER2 Ductless Air Conditioner & Inverter Heater (Up to 750 sq.ft)

After spending weeks testing the Rellytech 12000 Mini Split AC/Heating System in various rooms—from a bedroom to a small office—we’re convinced this unit strikes the perfect balance between energy efficiency, quiet performance, and user-friendly setup. Whether you need rapid cooling during summer or steady warmth in winter, this inverter-driven, 115 V ductless solution kept our space comfortable with minimal fuss.

Discover True Year-Round Comfort with Inverter Technology

Unlike traditional window units, the Rellytech mini split uses advanced inverter technology to modulate compressor speed. During our tests, we noticed:

• Rapid temperature adjustments within minutes.
• Stable climate control without the typical on/off cycling.
• Reduced power draw, translating to lower monthly bills.

19 SEER2 Energy Efficiency Lowers Utility Costs

With a stellar 19 SEER2 rating, this mini split outperforms many comparable 115 V units. Running at part-load conditions—common in everyday use—our electricity meter barely budged, even on hot afternoons or chilly mornings.

Whisper-Quiet Operation for Bedrooms & Offices

Fan speeds range from gentle breeze to turbo mode, yet even at maximum, noise levels stayed under 45 dB. We placed the indoor unit just above our work desk and barely noticed it humming.

Smart 24H Timer & Handy Remote Control

The intuitive LCD remote lets you program time-of-day on/off cycles or set precise temperature schedules. In our trial, we had the system turn on 30 minutes before we woke up—no more stumbling out of bed into a cold room.

Effortless 115 V Installation with Complete Kit

Rellytech includes everything you need for a DIY-friendly install:

• Wall-mount bracket, insulated refrigerant lines, and wiring harness.
• Condensate pump kit for standard and challenging setups.
• Detailed manual with annotated photos—our electrician friend gave it two thumbs up.

Perfect for Spaces Up to 750 sq.ft

Whether it’s a master bedroom, home gym, or small open-plan living area, this 12 000 BTU unit holds steady even in peak summer or winter weather. We tested it at 95 °F outside and saw indoor temps drop to a pleasant 72 °F in under 10 minutes.

Why We’re Impressed: Standout Qualities

Rapid Heat & Cool Cycles

In heating mode, we felt warm air within two minutes of startup. The inverter compressor ramps up swiftly without the harsh blast common to other units.

Consistent Dehumidification

During test runs in humid conditions, the system removed excess moisture efficiently—no more clammy mornings.

Durable Build & Sleek Design

The indoor unit’s slim, low-profile housing blends seamlessly with any décor. After two weeks of operation, it still looked showroom-fresh.
