Easy to install, works great. Could have used a few more feet of the wrap and drain hose.

An Excellent DIY Mini-Split: Quiet, Powerful, and User-Friendly ?. As a first-time DIY installer, I am incredibly impressed with this mini-split system. The performance is outstanding, and the unit is exceptionally quiet. ?Installation: The included kit is comprehensive, providing almost everything needed for installation. However, for a clean and professional-looking result, you will need to purchase the following items separately: ?a drill and appropriate masonry, drywall, and wood bit, ?line set wall sleeve/guard ?Outdoor condenser wall mount. A vacuum pump and gauge set (essential for proper installation) ?. I highly recommend watching instructional videos on YouTube before starting. Ensure all connectors are securely tightened, the refrigerant lines are not kinked, and you perform a thorough leak check to avoid common installation errors and the need to add refrigerant. ?Performance: The unit operates at a whisper-quiet level, both the indoor air handler (even on its turbo setting) and the outdoor condenser. It is a significant improvement over my previous portable floor AC, which was disruptively loud. This unit effectively cools my room, which has a west-facing window and would previously reach temperatures as high as 98F. Now, the room temperature can comfortably be lowered to 63F. ?Features: The accompanying mobile app has a clean, user-friendly interface that is simple to navigate. ?Overall, I highly recommend this unit for its exceptional performance, quiet operation, and affordable, manageable DIY installation process

I do not write reviews much, but this mini split is worth it. I purchased my Della 12k BTU unit a few months ago. I'm a DIY guy but was a little nervous installing this unit, as some of the information online made it seem difficult. Once I received our mini-split and unpacked everything, installation was easier than expected. I do want to note that you will need a vacuum pump and a set of A/C gauges. Once the unit was installed and running, my spouse and I were amazed at how quickly it cools off the 3 floor of our house. We do have central heating and air, but the 3 floor is constantly warm in the summer. After the first month of the unit running, we received our electric bill, and I was surprised that we saved 4 kilowatt-hours per day and our bill was $37.00 cheaper than the previous month. We just received our bill for July, and it's $43.00 cheaper than June, and we kept the house at 70 degrees both months. I would definitely recommend the Della 12,000 BTU mini-split unit to friends and family!

Not disappointed. Installs easily and works per design. This heat pump puts out a large volume of heat quickly. I'm delighted to say I have a heated garage! This is my second DELLA heat pump I've installed for myself.

So far this has been great. The app is what really makes it great. We've installed this on the food truck, and I can see the ambient temperature and perform a self-clean while at the office. We haven't used it through summer yet, but it has done great as a heater and for keeping the truck cool after a shift.

We have a back sun room with lots of windows. I was either blistering hot in there or freezing cold. We had this unit installed, and now we can enjoy this sun room all year round!

I have now installed 4 of these units. With a vacuum pump and a set of gauges, you can easily install these for much cheaper than hiring someone to do it.

The installation was super easy and the instructions were very clear. It took my son and I around 5 hours to install and that was taking our time. Neither of us have any HVAC experience. I wish that you could make the instructions for using the remote a little clearer.

My second Della and I will continue to buy Della mini splits for the simple reason - customer service, they truly stand by you. I brought my first Della two years ago, had to call Della for help, they were there. Two year later same service person helped me. Incredible, they remembered me, I remembered them. Because of the retention and energy and sincerity of the service people of Della, I am convinced that they kind of energy and commitment is translated into their products. So far I am absolutely correct!

System was easy to install and works fantastic! The indoor and outdoor unit are both super quiet. Only wish that the unit was shipped together and not from two different locations. Had a 3-4 day wait from receiving the indoor unit and then the outdoor unit.

I was replacing a ten year old Mitsubishi unit. Everything went well. My only thing is the bracket for the inside unit. I would like it to span wider to allow easier securing to studs. Now, I am considering one for my shop.
