Ductless units or mini splits – they are the bane of many HVAC technicians. The units themselves are quiet, super-efficient, and work very well. Often, technicians will say something like, “I install a lot of these units and they generally work great, but honestly I have no idea what’s really going on inside those things.” It’s a fair enough statement. Most technicians are accustomed to contactors, relays, capacitors, AC voltage motors, and simple I/O controls. There is nothing simple in appearance about the inner workings of a ductless unit.
For starters, we have the board which is located next to a 2nd board which is then located above a 3rd board. There are no contactors or relays. The only capacitors are built into the control boards. Controls? Yes, we have controls, but not the traditional I/O kind we usually think about. Nope, these things talk back and forth. What are they saying? Who knows!
Daikin has recently announced the launch of their updated SkyAir single-zone system products. It consists of new RZR cooling-only models and RZQ heat pump outdoor models (where the 18k, 24k, 30k and 36k heat pumps provide 100% heating capacity at -4°F), new FAQ, FCQ and FTQ indoor units along with the addition of 4-ton systems for FTQ, FCQ and FBQ.
Daikin SkyAir is a 2-wire light commercial and residential family of cooling only and heat pump single-zone systems, consisting of a variety of ducted and non-ducted indoor units, ranging from 1.5-4 tons with lineset lengths up to 230’ while backed with a standard 10-year parts limited warranty.
Details About the New FTQ Multi-Purpose Air Handler
This new air handler provides a traditional ducted solution with the benefits of an inverter, variable-speed compressor in a side-discharge outdoor unit.
The FTQ is capable of upflow, downflow, horizontal left and horizontal right installation configurations and is designed for ZERO clearance on three sides and only 24” clearance on the front for service. It also has a smaller footprint compared with previous models, with a depth of 21”, width of 17.5-21” and a height of 45-53.4”. The smaller size provides easier attic and mechanical closet installations. It also comes standard with a factory installed disconnect switch and efficiencies of up to 16.0 SEER, 12.5 EER and 10.4HSPF (heat pump only).

The Daikin Comfort Control App allows users to control their Daikin systems with a compatible phone or tablet from anywhere they have a data or wireless connection. This is purchased as a kit and is field installed to operate most Daikin single and multi-zone systems while also providing a much more cost-effective alternative to a wi/fi wall controller.
