π Documents & Resources
Comfort Mode
Automatically adjusts airflow direction so cool air doesn't blow directly on occupants, and heats by driving warm air vertically to the floor — eliminates cold spots and drafts.
Built-In Wi-Fi + Daikin App
Control your system from anywhere via the Daikin Comfort Control app on iOS and Android. No add-on Wi-Fi module required.
Titanium Apatite Filter
Combines an air-purifying filter with a photocatalytic deodorizing filter in one unit — breaks down odors, viruses, and organic particles for better indoor air quality.
Hot Start Function
When the unit changes from cooling to heating, pre-warms the coil before the fan starts — no cold draft on startup.
Econo Mode
Limits the maximum operating current and power consumption of the outdoor unit by approximately 30% during startup — saves energy and reduces load on your electrical circuit.
Powerful Button
Gives you a 20-minute boost in cooling or heating power at the push of a button — even if the unit is already operating at high capacity.
3-D Airflow
Combines vertical and horizontal auto-swing to circulate air through the entire room — eliminates hot and cold spots more effectively than single-direction airflow.
Weekly Timer
Set daily and weekly schedules for automatic operation — wake up to a warm room, or arrive home to a cool house without touching a remote.

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 Daikin warranty also depends on professional installation and online registration 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?
This listing doesn't explicitly state whether a line set is included. Confirm with us before ordering. The outdoor unit is precharged for up to 49 ft of liquid line — check the Install Manual linked above for the exact line-set specifications and refrigerant charge requirements.
How does the Add to Cart promotion work?
This item is eligible for our current Add to Cart promotion. Add the system to your cart to see the promotion applied at checkout. If you have questions about the promotion terms or need help with a specific order, call or email our team and we'll walk you through it.
Can I extend the low-ambient cooling range?
Yes. This system has three cooling tiers: Standard (50°F outdoor ambient), Extended with optional wind baffle (down to -4°F), and Extended with J6 jumper cut (down to 5°F). Cutting the J6 jumper requires a field technician to modify the circuit board on the outdoor unit. The wind baffle is an add-on accessory that protects the coil in cold, snowy, or windy conditions. Standard cooling is fine for most residential applications — extended cooling is useful for server rooms, greenhouses, and year-round cooling.
