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.

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!! :) Coming up on two years later, still loving it, no big issues. My kids generally keep their rooms much colder than I do with mine, I’m at maybe 78°, they are both around 70°. Electric bills, even with the kids temps have never come close to what the electricity wasting central air system cost me. It seems year round, summer or winter, the bills average within $100, and that can be a couple hundreds less than the old summertime bills. The only “issues” are that the app drops its connection to the rooms, very randomly, but it takes a minute to get it back online again in the app. Never an issue using the remotes. The second thing is, the damn kids will still have AC going in their rooms when I want heat. Damn kids!! 🤣 Just something to be aware of, you can’t split the service, you can’t run AC on one, heat on another at the same time. That’s it, all good and still very happy with my purchase.

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!!!

Well we saved money by buying these and doing it ourselves. My husband is a sprinkler fitter and has some construction knowledge. I have a 1000 square ft house and we put one in the basement, one in the living room and one in our bedroom. The window AC were killing us at 400+ electric bills and the house was uncomfortable and not that cool. The window AC if I cooked the house got hotter, but with this unit it was awesome. My bills went down and I was finally comfortable. I have boiler heat in this house and we tested the heat and they work great and if my boiler goes out I’m glad to have a back up. FYI they need a way to drain. I think the drain tubes provided are cheap and you can up grade that

It does come with everything but everything is short 16ft you’ll find out isn’t enough and you’ll end up having to get longer lines and cables. Our house is only 1200sqft and the wires are just not long enough at all to reach the condenser.
