Bosch 9K BTU 27.4 SEER2 Gen 4 Wall Mount Mini Split Single Zone Max Performance No Lineset 230V R454B

The Bosch Climate 5000 Gen 4 ductless mini split heat pump kit is designed for homeowners seeking efficient heating and cooling without the need for extensive ductwork. This 9,000 BTU system offers both energy savings and comfort with its advanced features like an inverter compressor and self-cleaning blue-fin technology, making it ideal for small to medium-sized rooms or spaces where traditional HVAC systems are impractical.


Bosch Climate 5000 Gen 4 9,000 BTU Outdoor Condenser - R-454B | 230V BMS500-AAS009-1CSXHD

The outdoor condenser model BMS500-AAS009-1CSXHD is the powerhouse of this mini split system. It operates efficiently in a wide range of temperatures, from as low as -13°F to over 122°F, ensuring reliable performance year-round.

Superior Heating & Cooling Performance

  • 21.4 SEER2: delivers strong seasonal cooling efficiency that helps trim energy costs through the summer months.
  • 12.5 HSPF2: provides efficient heat-pump warmth for cost-effective comfort when the temperature drops.
  • 13.4 EER2: holds solid efficiency under peak-load conditions on the hottest days of the year.
  • Cold-Weather Output: rated heating capacity of 10,000 BTU at 47F, 9,800 BTU at 17F, 11,500 BTU at 5F, with a COP of 1.89 at 5F for dependable heat as it gets cold.
  • ENERGY STAR Cold Climate: certified for reliable performance in genuinely cold climates, not just mild weather.
  • Wide Operating Range: engineered to cool and heat across a broad outdoor temperature range for year-round comfort.

Advanced Technology

  • Inverter Compressor: continuously varies its output to match demand instead of cycling fully on and off, saving energy and holding steady temperatures.
  • R-454B Refrigerant: uses an eco-friendly, low-GWP refrigerant that meets the latest environmental requirements.
  • A2L Safety Sensor: a factory-installed refrigerant sensor adds an extra layer of built-in safety.
  • AHRI Certified: performance ratings are independently verified, so you know exactly what you are buying.
  • Variable-Speed Operation: ramps smoothly to keep rooms at a consistent temperature while minimizing energy use.

Whisper-Quiet Operation

  • Whisper-Quiet: the inverter-driven condenser runs quietly for an unobtrusive presence outside your home.
  • Smooth Ramping: variable-speed startups avoid the loud kick-on of traditional single-stage units.
  • Compact Footprint: a compact outdoor unit fits neatly on patios, balconies, and tight side yards.
  • Low Vibration: the inverter design keeps outdoor operating noise and vibration to a minimum.

Durability & Long-Term Protection

  • Blue-Fin Coating: water-wicking blue-fin technology resists corrosion to extend the life of the coil.
  • Weather-Resistant Build: engineered to protect internal components against the elements year-round.
  • Flexible Line-Set Runs: supports long line-set runs so the outdoor unit can sit where it fits best.
  • Compact Install: the indoor and outdoor units connect through a small exterior wall opening.
  • No Ductwork: requires no ducting, making it ideal for additions, renovations, and enclosed spaces.

Warranty Coverage

  • 7-Year Parts: replacement-parts coverage for 7 years, extending to 10 years when you register the system.
  • 10-Year Compressor: a full decade of protection on the compressor, the heart of the system.
  • Professional Installation: warranty coverage requires professional installation for lasting reliability.

With its robust design and energy-efficient operation at 21.4 SEER2 and 12.5 HSPF2 ratings, the outdoor condenser is built to last and save on utility costs, making it a smart choice for any home heating and cooling solution.
