## Description

Features: Heat or cool your space efficiently with this split air conditioner. This preloaded air conditioner is equipped with a mini wireless split inverter plus system with heat pump and dehumidification. The device can be easily controlled and configured via the remote control or via the Dellla app. The set includes all the needs for an easy installation experience.

Review: I bought this mini-split unit because it is one of the few that I could install myself. Although it requires having a vacuum pump and a vacuum gauge set the investment in tools is minimal compared to the cost of having a unit like this professionally installed. Please note: the unit itself is very straightforward as far as connecting the inside and outside units together and charging the system HOWEVER there is a significant amount of additional work that needs to happen to actually get the unit fully installed on your house. This additional work may include running new electrical branch circuits through your house, opening up walls with all of the associated drywall, stucco or siding repair, possible concrete work, possible plumbing work, finishing work to cover the refrigeration pipes, etc. Just be certain that you know what you are getting into before starting this project. That said, I did install the unit myself, it turned out great and I am very happy with it but it was considerably more work than I had anticipated. The unit itself is fantastic! It cools my 12' x12' bedroom down in minutes and has enough additional cooling capacity to keep my entire house cool on a 100 degree day just by placing a small fan at the door of the bedroom that blows the cold air to the rest of the house. At night it keeps the bedroom cool while making hardly any noise. The noise that it does make is a quiet ssshhhhhhh sound that is about as loud as a whisper and it works perfectly as a white noise generator. The outside unit is also very quiet. When I first turned it on I didn't even realize it was running. I chose to wall mount the outside unit on brackets as opposed to bolting it to a concrete slab but I imagine it would be even quieter if it was slab mounted. If you wall mount it you will need to purchase brackets separately. There are specially designed brackets specifically for mini-splits and they are relatively inexpensive. So far my only complaints about the unit itself is the lack of adequate protection for the refrigerant lines. The tape wrap that comes with the kit is woefully inadequate in my opinion and I ran out of the tape with several feet left to go. Even with the tape the lines appear unfinished and are poorly protected from the elements. To address the issue I bought a mini-split duct kit to cover the lines which resulted in a well protected, professional looking final installation (see picture). Consider this step an absolute necessity. I decided not to bother installing the wifi control app on my phone. Based on what I could see the only additional advantage of the app is being able to set schedule times which is a feature that I don't use. Considering the immense value for this mini-split unit I would absolutely recommend it as long as you are an advanced level DIY'er. If you are not comfortable dealing with electrical installations and the National Electrical Code and if cutting a big hole through your wall scares you then I might suggest finding a different solution to your cooling situation.
Review: Quality is outstanding on these units. They are super quiet, This is now my 3rd one. These are very energy efficient, Easy to install, just install as directed, vacuum the lines and turn it on. It will heat and cool great. I have it on rooms around 350 square feet and it will freeze you out.

*by K***R on 1 April 2025*

Very easy to install. We installed in the dining area which was an add on. It has a high ceiling and the heat seamed to get trapped keeping the area hot during the summer months in South Louisiana. Once installed there was an instant change and the area stayed cooled. We set the temperature to match the thermostat for the main home AC. Works great and highly recommend this product. Room Size is about 200 SF The walls are white and it looks great in the room. Very quiet.
