Description

Delivering reliable heating and cooling for medium to large rooms up to 1,000 square feet, the Pioneer 24,000 BTU Diamante Pro High-Wall Series Ductless Mini Split brings efficient, inverter-driven climate control to spaces where traditional ductwork is impractical or unavailable. Its ductless design streamlines installation, while the high-efficiency compressor helps you maintain steady indoor temperatures year-round.

Whether you're outfitting a new addition, a converted garage, or a small commercial office, this mini-split system pairs advanced variable-speed technology with a compact indoor air handler that mounts high on the wall, keeping valuable floor space clear.

Key Features and Benefits of Pioneer 24,000 BTU Diamante Pro Mini Split

Inverter Technology: The variable-speed compressor automatically adapts output, minimizing temperature swings and lowering energy consumption during part-load operation.
High Efficiency Ratings: With a 21 SEER2 cooling and 9.5 HSPF2 rated heating performance rating, you spend less on electricity while meeting local energy code requirements.
Four Operating Modes: Switch between Cooling, Heating, Dry, and Ventilation to match seasonal demands and improve comfort without purchasing separate equipment.
Ultra-Quiet Operation: Indoor sound levels start at 28 dB, so the system runs unobtrusively in bedrooms, offices, or study areas.
Dual-Axis Airflow: Motorized horizontal and vertical louvers distribute conditioned air evenly, reducing hot and cold spots across the room.
ECO and SLEEP Modes: Automated modes trim energy use during quiet hours, helping you meet efficiency goals without manual adjustments.
Washable Filters: Reusable intake filters capture dust and are easy to clean, cutting replacement costs and keeping airflow strong.
Line Set Included: This model includes a 16-foot 1/4 x 1/2 Line Set.

Note: This mini-split air conditioner must be installed by a qualified professional.

Built for Extremes

The Diamante Pro is engineered to handle harsh weather without compromising indoor comfort. Its compressor and electronic controls are rated for continuous heating down to -4 degrees F, making it a practical option for colder regions that still want the simplicity of a single-zone ductless system. On the opposite end of the spectrum, cooling operation remains stable up to 122 degrees F, safeguarding productivity in workshops, server rooms, and sun-facing offices.

In addition to robust performance, the system uses R-454B, a next-generation refrigerant with a lower global warming potential than many legacy options. By selecting equipment already optimized for future regulatory standards, you reduce environmental impact and position your facility for upcoming refrigerant transitions.

Sylvane’s Expert Take

For contractors and facility managers seeking a dependable, single-zone solution, the Pioneer Diamante Pro combines impressive efficiency, broad operating limits, and straightforward installation in one package. The included line set, inverter drive, and low-ambient capability shorten project timelines and cut ongoing costs. Quiet operation and dual-axis airflow further enhance occupant comfort, making this mini-split a smart choice for both residential and light commercial applications.
