Style: 12,000 BTU - 230V / 23 SEER2
I've had this for a couple years now and I thought I'd review it. Installed it in the garage and it works great. My dogs love it and I love it. Having a temperature controlled area to work and for my dogs to get out of the sun is awesome. Super easy install if you know what your doing. It's quiet and we run it quite often and haven't noticed much difference on our electric bill. The one I got has a heat pump so it cools and heats.

The DELLA unit is working wonderfully! I did have it professionally installed, but for the most part it was definitely DIY able (biggest problem would have been the need to vacuum the line set down). It does a wonderful job heating and cooling my studio.

Had a A/C service install the unit, I’m disabled, but it’s very straightforward from what I could tell if you have some mechanical and electrical skills along was following directions, it shouldn’t be hard to install. The unit cools and heats well. I’ve had the heat on to dry out cabinets in my shop/office after painting them. So far I’ve been very satisfied with this unit. Seems well constructed and runs efficiently! It’s very quiet and just what I needed. Where I live it’s hot and humid, but cools great. I recommend it!! UPDATE: IVE BEEN USING THIS UNIT FOR 8 months now. It’s great, super quiet and cools well when it’s over 100 degrees and heats well down into the 20’s with the wind blowing hard most of the time. I’m impressed. My Air Conditioning Tech was impressed with it as well. He commented several times how well it was made and that the compressor adjusted to the demand, said that’s extremely important.

This unit does not work. The fan comes on for about 5 min and kicks off for hours. Sometimes it won’t come back on until you mess with the settings on the remote. Sometimes that doesn’t even work. Sometimes if you hit the swing button it will turn the fan on. My home is freezing because this thing is worthless. Reviews seemed good so I made the choice to purchase. Biggest waste of money. I did have it professionally installed. Contacted the customer service number. Spoke with Adrian. All they did was email troubleshooting guides. Most of which came with the until and the one is in Chinese. I do not read Chinese. They were not help. As he advised I emailed him back and told him they were of no help. He asked to confirm the line set has been properly attached and free of damage. Well yes. I already told him that on my first call. Everything is installed correctly but it still does not work. I emailed back telling him that. So it’s not a quick process to go through customer support to remedy the issue. Through Amazon the only option is to return the product and wait for them to receive the item and return the money back. They won’t send a replacement. Well we need the unit. Temps are super low right now and we had this installed prior to move in. We are now moved in and don’t have the option of going without heat. I’ll wait for a reply from customer service but looks like this will be going back. If anything changes I will update the review.

Bought the 21 SEER 12,000 BTU for 700 ft upstairs living area. Worked great to keep in the low 70s all summer. Bought the 19 SEER 12,000 BTU and the 24,000 BTU for the 4-car garage/workshop areas. The only difference between the two 12,000 BTU units was the length of the refrigerant lines. The 21 SEER has a 6 ft line, the 19 SEER has a 25 ft line. We needed longer lines for our garage units. The 21 SEER seemed to work better in keeping the area cool, but the house insulation is better than the workshop. The units did a great job keeping us cool for the 100+ 4-month long Texas summer this year. The reason for 4 stars instead of 5 is because we did not know about the yearly maintenance required to keep these units mold free. There are videos on YouTube that explain how to clean these units to remove mold. The one we liked best was DIYJIM cleaning a Mitsubishi unit. Our unit was harder to clean as Della's blades that move air up and down do not come out. The Mitsubishi's easily slide out to give better access to the side to side airflow blades and water pan. Della should follow Mitsubishi's air flow blade design. I had to wrap a wet cloth around a long thin stick to clean the horizontal airflow blades and surrounding area. I used a 50/50 vinegar/water solution to do this as vinegar kills mold. We used the unit for four months so were happy to only have minor spots of black mold on the horizontal blades. There was no mold on the "hamster cage" cylinder fan so we only had to vacuum it. We did discover that one should leave the unit on 24/7 to allow the unit to remove standing water. We often turned it off if the temperature became too cold. We now will just adjust the unit to a higher temperature. As said before, the units work great and are easy to install/use; however, I do not like the idea of mold growing in the units. I don't think this is a problem with central air conditioners. A couple times towards the end of our 4 months continual use, we had water dripping inside the house off the airflow blades. We believe this was because of excess water due to outside humidity and the unit not draining the water effectively. The a/c man that installed a friend's duckless unit installed it at a slant so the side with the hose line for water removal is slightly lower. Our units were installed level as shown in the instructions. If we were to do it again, we would install them slightly tilted towards the water hose end. They do use less electricity than central, but not as much as we had hoped. Maybe 40% less. The price they are showing now is much lower than what we paid. Our 12,000 units were around $1,000, now it shows them at $700.
