BlueFin Anti-Corrosion Coating

Advanced coil protection safeguards the outdoor unit against harsh environmental elements and coastal salt air, ensuring long-term durability.

Smart Airflow

Features a 37% larger flap that distributes air upward, wider, and further for total room coverage — eliminates hot and cold spots.

Frequently Asked Questions

Will my warranty be valid if I don't use a licensed installer?

No. This is a traditional line-set system — brazing, evacuation and charging the refrigerant circuit must be performed by an EPA 608-certified technician. The Daizuki warranty also depends on professional installation and online registration within 60 days of installation via the link in the warranty section above. Our team can answer sizing and line-set questions before you order — just call or email.

What is a wall mount mini split, and what spaces does it fit?

A wall mount mini split is a ductless indoor unit that installs high on a wall, above furniture and away from foot traffic. It's the most common mini split form factor — ideal for bedrooms, home offices, living rooms, additions, and single-room commercial spaces. At 18,000 BTU, this system is sized for roughly 500–750 sq ft depending on ceiling height, insulation, and climate.

Does this system include a line set?

Yes — a 10-foot install kit is included with the outdoor unit. Note that 10' is shorter than most standard line sets (typically 15' or 25'). If your installation requires a longer run, verify with Daizuki before extending — line-set length affects refrigerant charge.

How long is the Daizuki warranty, and what does it cover?

The Daizuki DXTHA-25 Series carries a 5-year compressor / 2-year parts warranty. Registration is required within 60 days of installation to activate coverage. The Warranty Terms page linked above covers the full terms. Registration is done online at the link in the warranty section above.
