- [AMPLE COVERAGE] This AC able to work in environments as low as 5 degrees Fahrenheit provides heating for up to 1650 Sq. Ft (3 indoor unit recommended area 550 Sq. Ft) . Full installation kit included. Additionally, it uses the more environmentally friendly R454B refrigerant.

- [MULTI ZONE CAPACITY]: This configuration is designed for spaces where not all indoor units are expected to operate at full power at the same time. If the total indoor capacity is higher than the outdoor units output, the system can still function properly, but cooling or heating performance may be slower when all zones are operating beyond capacity. For consistently high demand across all zones, a larger or multi-system setup is recommended.

The system is Great-Super Quiet and Efficient. BUT if you buy directly from Della's website they have better customer support for switching parts like linesets lengths(copper and electric lines from outdoor unit to indoor units) for free and warranty details. For a 1200 sqft house we bought a 27K BTU (3 indoor unit system, 9K, 9K, & 12K) that came with 3 16' linesets, but we needed 2 50' linesets. If we bought from Della directly they would have exchanged for free, but buying from Amazon we had to put out another $600 for 2 longer linesets. Easy to install if you're an avid DIY. No ductwork, which is excellent for flood areas. Mount units on wall, run linesets (in or thru walls) to outdoor compressor, run 220V service to outdoor unit with a disconnect. We built a 5' high stand for outdoor unit. We had a HVAC company come to make the final lineset connections and startup (about $500). Haven't had a need for the heating part; will update later. Wish I had done this years ago!!!

The old, undersized central air was not cutting it. I spent a while researching mini split units and decided to go with Della. Having never installed one before, I read a bunch, watched a lot of video, went for it. Took my time, took two days to fully install the three indoor units, in very hot weather. If you are a DIY'er, I would not hesitate to install one of these. Bending the copper, just take your time, support the bending, all good. One unit is not on an exterior wall, I tried two different pumps, one did not work at all, the other was questionable, I ended up doing an alternative drain hidden in closets to the garage and the washing machine drain, much better! If you can, forget about the pumps and figure a way to drain using good 'ol gravity. Saves you money, works better, no additional maintenance issues. The kids, having their own control of their room, and with their doors never left open, these units work so much better. Using the app on my phone I can see just how cold they keep their rooms. Quite cold!! Once the room is cooled, the unit is really not working much to maintain that temp. Still waiting for my first bill!! :)

Not as easy of an install as I would have liked but definitely doable. That's the only reason it's not getting a 5 star, I feel like something I order off Amazon should be very DIY. The product cools great and it's quiet inside and outside. I did have to order the 50 foot kit to get all 3 units hooked up where I wanted them.
