  • excellent product
Size: 12,000 BTU - 115V -- 20 SEER2
This is 10th Della mini split we have purchased and installed since January 2024. We have only had one issue with a reset code issue and it was resolved quickly and efficiently. getting ready to order another. excellent product.

  • Updated. Not fully installed yet...will update
To be clear, I have not completed installation yet. I am doing it slowly because I think I will have to order more parts etc. and don't want to stress. But I wanted to give my impressions as I go along. PRO: - very sturdy materials and well built and clean looking. - Arrived quickly CONS: - There really are NO instructions. What they provide does not make sense and goes out of sequence. There are vague references to electrical connections, but not how to find where to connect the cables! Hint: open up the blower unit, then open the panel to the right by undoing the one screw. There is no info on how to move the drain pipe. AND NO template!!!!! Drilling a hole in your wall is guesswork! I'm pretty handy and still got it off a bit and the hole shows a bit under the wall unit. - The website is "Powered by WordPress" which is concerning that they didn't even edit that out! So it's iffy if the company is legit and has any staying ower since they don't have a proper website. - I contacted support 4 days ago and still no reply. - There is no way to register the unit for a warranty. In their drop down, spilt units aren't even an option!!! - The black unit I bought doesn't even show as an option on their website!! - The website contains NO usefull information...no manuals, downloads, only one line of text about the units. - The lines are short, maybe 10 feet! So I am worried about placement of the compressor and will more than likely have to spend another $80 to buy new lines (so consider this when price comparing) UPDATED: fully installed. Used YouTube plusn other resources to install. The hardest part: bending the tubing without pinching it! It was hard to get it all lined up nicely. And the length you can see, just fit. The unit works great!! I can barely hear the inside unit when on low, and on high it's still very quiet!! You can turn the display off as well to eliminate all light! The outside unit is so quiet that I thought it wasn't working!! I actually had to go out and check it, haha. The app is just a version of Smart Life, but if you want to use Amazon echo, you have to add the unit to Smart Life and it functions ok but there's a lag on the app. Using the Della app, it worked perfectly very responsive. I emailed and asked about it but as seems to be the status quo, no reply from support. But it works great with Alexa, the remote is fine as well. Overall I am very pleased with the unit! ... show more

  • Helps on energy bills
Size: 12,000 BTU - 115V -- 20 SEER2
This thing rocks, I installed mine late October 2023 and it's been chugging along ever since. Heating bills are down considerably and it runs so quietly. The smart home feature has worked flawlessly since day one but that can always change. Integrates with home assistant if that is something you do too. Overall its a fun project to install if you like DIY stuff, and it really cuts down on bills. Win / Win ... show more

  • No hvac experience, no problem AND IT WORKS WITH ALEXA
First and foremost... This product is designed to be installed by a professional. Lots of key information is not in the manual most likely because this is probably first hand knowledge for an experienced hvac person. Information missing from previous reviews. 1) the larger line on the indoor unit is pressurized. Be careful removing the cap. 2) the outdoor unit MUST have the lines seated properly. 3) on the outdoor unit you must remove the copper caps(the ones pointed away from the unit) and open the valves ONLY AFTER you have properly seated the copper lines. You will hear a slight hissing as the coolant fills the lines. If the hissing last longer than a few seconds or you see liquid escaping you need to close the valve immediately and either seat your line better or find the leak. 4) batteries supplied were dead. The remote will still light up, but won't power the unit on in that case. I think that covers all the info missing that we managed to figure out. Unit is incredibly quite inside and out, powerful fan, super sleek, android setup was a breeze. Very happy with this unit. ... show more

  • Hotel cold at home 🤭
Size: 12,000 BTU - 115V -- 20 SEER2
We have zero regrets! No wait, one. That we didn’t get them sooner! We (my husband, self and 19yr old son) work outside noon-8am several days a week in Texas. It doesn’t matter how low you set your AC unit it’s just never enough and it just runs it into the ground. We finally decided to pull the plug. In my 40 years I’ve never slept so good. It’s like hotel good but in your own bed!!! Install was super easy because I watched him do it, LOL. I kid. I’ll ask for his install input and update but seriously he installed all 4 (3 bedrooms and 1 living room) in 2 days. Probably wouldn’t have taken so long if he didn’t have to pour a pad for them but it was well worth it! Last pic is from the Nest. They were installed Friday. Compare usage from Sat & Sun to before we got them! Insane!!! ... show more
