Features 5

  • CAPACITY AND EFFICIENCY: This 18,000 BTU mini split is a 230V AC/heating system with 18,000 BTU/H cooling capacity, 21.0 SEER2 efficiency, 18,000 BTU/H heating capacity, 9.5 HSPF2, and R-454B refrigerant. Built for reliable year-round performance, it is backed by AHRI, ETL, DOE, and ISO 9001 certifications, with NEEP ASHP recognition for cold-climate capability. Recommended for 500 to 750 sq ft; operates down to -4F in heating and 122F in cooling.
  • DUCTLESS ALL-SEASON COMFORT: Built as a mini split heat pump, this single zone mini split air conditioner provides cooling, heating, Dry, and Fan modes for one room or defined zone. The ductless air conditioner delivers independent temperature control without extending central ductwork, while its variable-speed DC inverter compressor adjusts output to demand for steadier comfort and efficient part-load operation.
  • DUAL-AXIS AIRFLOW AND LOCAL SENSING: The slim wall mounted air conditioner uses motorized up-down and left-right louvers to sweep conditioned air throughout the room. The included mini split remote control features I FEEL sensing, which detects temperature near the handheld controller for more personalized comfort, plus Turbo, Mute, Eco, Sleep, Timer, and Memory functions. Optional Pioneer AirLink app control requires a separately sold module.
  • QUIET, EASY-CARE INDOOR UNIT: Variable fan speeds and Mute mode help the indoor air conditioner run with less distraction, making it a quiet air conditioner for bedroom use and a practical garage air conditioner when capacity is matched to the space. A washable, reusable dust filter reduces routine replacement needs, while the self-clean cycle supports simpler upkeep between regular cleaning and professional service.

Description

Bring focused comfort to additions, renovated rooms, garages, workshops, rental units, and light commercial spaces where extending ductwork is impractical. The Pioneer WYT-20 Diamante Pro is a ductless mini split air conditioner that pairs a sleek high-wall air handler with a compact outdoor condenser. This split unit AC and heat solution provides Cooling, Heating, Dry, and Fan modes, giving one room or defined zone independent temperature control when capacity is correctly matched to the space. A variable-speed compressor lets the inverter air conditioner adjust output as conditions change, supporting steadier comfort without constant full-output operation. Motorized left-right and up-down louvers spread conditioned air across the room, while I FEEL senses temperature near the handheld controller. The slim wall mount air conditioner also offers Turbo, Mute, Eco, Sleep, Timer, Memory, LED display control, and a self-clean cycle. Washable, reusable filters make routine care straightforward. The package includes the indoor and outdoor units, handheld controller, holder, batteries, insulated copper connections, signal cable, drain hose, wall sleeve, putty, sealer, wrapping tape, drain spout, rubber mounting feet, and manuals. Optional Pioneer AirLink app control requires a separately sold module. Install this mini split AC unit according to the supplied instructions, local codes, and applicable HVAC and electrical requirements.

Air conditioner is very efficient and does a great job
Style: 18000 BTU - 230V
So far really good. Very efficient. Easy to install DIY the whole thing took me one weekend. Borrowed my brother's vacuum pump keeps my home cool. I need to add more but currently this is cooling 1500 square feet in California and it keeps my house around 75° on 100° day

This split system is so quiet when it's running. Good value for the cost. Arrived very quickly, and was easy for our installer to install. It cools and heats perfectly. So far it is very reliable.

So quiet
Style: 18000 BTU - 230V
This Pioneer Pro is just what we needed to cool down our hot garage. It’s so quiet and cools down so quickly and efficiently. With the help from my brother in laws , we were able to install it in one day. So glad we purchased this, so worth it!!

So far its been great.
Style: 18000 BTU - 230V
Fairly easy to install, blowing cool air in my workshop. I followed the instruction manual, and the installation went smoothly. Outdoor unit did have some bent fins and dented sheet metal upon arrival, but I believe it to be cosmetic. Quiet, cold, and worth it. I am told the warranty does not require installation from a licensed HVAC contractor. ... show more
