Product Data Table

This table highlights the key performance and installation factors buyers should consider before purchasing.

Energy Efficiency and 23 SEER Performance

One of the most impressive features of the Kinghome KW12HQ2B8D 22 SEER split unit is its high 23 SEER rating.

SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner operates over an entire cooling season. The higher the SEER rating, the more energy-efficient the unit is.

Why 23 SEER Matters

• Lower electricity bills
• Reduced environmental impact
• Improved long-term savings
• Compliance with high-efficiency standards

Compared to older systems that often operate at 13–16 SEER, this 23 SEER mini split can significantly reduce energy consumption.

For homeowners in warm climates where air conditioning runs frequently, this high efficiency translates into noticeable savings.

Cooling Performance – 12,000 BTU Output

The 12,000 BTU cooling capacity is ideal for:

• Bedrooms
• Small apartments
• Home offices
• Studio spaces
• Converted garages

With a maximum airflow of 400 CFM, the unit distributes air evenly throughout the room. This ensures:

• Consistent temperature control
• Reduced hot or cold spots
• Faster cooling cycles

The inverter-driven compressor adjusts output dynamically instead of constantly turning on and off, which improves comfort and reduces wear on components.

Heating Capability – Reliable Even at -4°F

Unlike standard air conditioners, this model includes a heat pump function with a 13,000 BTU heating capacity.

A standout feature is its ability to provide heat in outdoor temperatures as low as -4°F. This makes it a strong option for colder climates where traditional heat pumps may struggle.

Heating Benefits

• Year-round climate control
• Energy-efficient alternative to electric heaters
• Quiet indoor heating
• No need for separate heating system

This dual-function design makes the Kinghome KW12HQ2B8D mini split system a complete solution for both summer and winter.

Design and Build Quality

The Violet Series features a sleek, modern design with a clean white finish and integrated LED display. The indoor unit measures:

• 33.268 inches wide
• 11.378 inches high
• 8.228 inches deep

Weighing only 22.12 pounds, it is lightweight and easy to mount on most interior walls.

The outdoor unit is more robust at 85.9 pounds, built to withstand outdoor conditions while maintaining efficient heat exchange.

The compact footprint of both components allows for flexible installation options.

Installation and Included Accessories

The system includes:

• Line sets
• Remote control

Having the line sets included reduces installation complexity and additional purchasing requirements.

Installation Considerations

• Requires 230V electrical connection
• Professional HVAC installation recommended
• Proper refrigerant handling required
• Wall mounting for indoor unit
• Outdoor unit placement on bracket or concrete pad

Because this is a cord-controlled electric mini split, correct voltage setup is essential for safe operation.

Refrigerant and Environmental Impact

The Kinghome KW12HQ2B8D uses R410A refrigerant, which is widely recognized for:

• Improved heat transfer efficiency
• Zero ozone depletion potential
• Better cooling performance than older refrigerants

R410A systems typically operate at higher pressures, contributing to better efficiency and performance.

LED Display and Smart Control

The built-in LED display offers:

• Clear temperature readings
• Mode indicators
• Easy monitoring

The included remote control allows users to:

• Adjust temperature
• Change fan speeds
• Switch between cooling and heating modes
• Set timers
• Activate sleep mode

This provides full control without needing to access the indoor unit directly.

Usage Scenarios

Residential Applications

• Bedrooms
• Guest rooms
• Living rooms
• Home offices
