Description
The Daikin FTXQ-ASBU9 is a single-zone Oterra Series wall-mounted indoor unit available in 0.75 and 1-ton sizes, designed to pair with a matched Daikin RXQ-ASBU9 outdoor condenser for a complete 115V single-zone system delivering 20.0 SEER2 efficiency. It’s a good fit for rooms without floor space for other heating/cooling options.
At the core is a Daikin swing inverter-driven compressor that runs continuously and adjusts speed to meet demand, providing up to 30% energy savings compared to standard fixed-speed compressors. The system runs on R-32 refrigerant, which is up to 12% more efficient than R-410A with a lower global warming potential. Installation is simplified with Daikin’s SIGNA flareless line adapters, included with the outdoor unit, which eliminate the need to flare refrigerant lines — installers simply cut the line set, connect, and tighten.
Automatic defrosting keeps heating performance consistent in colder weather, and the system is compatible with the DKN Cloud App for remote Wi-Fi control from anywhere.
Backed by Daikin’s standard limited parts and compressor warranty; installation by a qualified, licensed HVAC technician is required to maintain warranty eligibility.
