I bought the unit for hurricane season. I have hooked it up and tested the unit. It cools for a few minutes then the ac kicks off and only blows air. If i turn it off after a few minutes it will start cooling again. The water drains out of the unit so I don’t think it’s that.

Installation was easy, there are plenty of videos online. What I find lacking are the explanations for the controls. As another reviewer noted, it doesn't seem to shut off when it reaches the temp it's set for, but just keeps running.

the unit is quick to cool down my garage (she shed), but it keeps going. i'll have to shut it off, for a bit. the unit warms great, but not my feet area. i saved a ton ($5k) buying it myself and having a tech install, which was more than the unit. overall, i love the unit but it has some flaws. the unit is DELLA 18000 BTU Energy Saving Mini Split 19 SEER2 Cools Up to 650 Sq.Ft Wifi Split Air Conditioner & Heater Ductless Pre-Charged Inverter System with 1.5 Ton Heat Pump(JPB Series with R32 refrigerant)

Installed unit a year ago myself. I watched YouTube videos and it took me about three hours to finish the install. Was pretty easy really. Heats and cools our 450 sq. ft. room quite well. I only gave it four stars because louvers on air handler only pivot up and down and not side to side. The other issue is that when using the heater if it’s below 32degrees the unit freezer up and shuts off. It makes a cracking ice sound before shutting off.

These units are the bomb. But I do not like the beeping sound. even if I hit the silence button it only works once then you hear the beeping again. Plus it is very hard to download onto your phone!

Install was ok and works great so far. 3 months. Moves a lot of air but still is almost silent. Seems better than the Mr cool I replaced which was not a long lasting unit. More expensive- worked barely 3yrs with a lot of maintenance required. Hope this one is much better. Funny how they never ask for review years later just right after initial purchase.

On the Della 12000 I need to have more info on how to total clean the head, how to take apart the squirrel fan head, and clean. A diagram on how to do it. ( part by part )
By Sandy T.
The product is amazing. Would be 5 stars if there were a way have the system shut off or 'pause' when a pre-determined temperature is reached. The fan runs regardless of temperature. System is efficient and extremely quiet (next to inaudible)
