I could no longer deal with the heat of this summer so I decided to give this unit a try. It is providing an indoor temperature drop of 10 degrees even though I'm not following guidelines for optimal cooling like closing off adjacent rooms. It's very quiet, even at the highest setting. I'm pleased with the purchase and feel it was money well spent.

This is their newest model. A lot quieter and sleeker looking. Cools faster too. Had the last one for about 10 years before the fan/bearing went. Does not pay to repair these units. Supposed to come with a cover for winter storage as it said on the box. It was not incluced. Wrote to the company and they sent one within week.

I purchased this unit for our 675 sq. ft. detached garage so my husband would be able to continue his work when it's really hot outside. It's working great for our purposes. I didn't expect it to make it cold in there, as it's in full-sun all day and only the roof is insulated, but I was hoping it would keep him comfortable enough to continue working without worrying about him getting sick from the heat. It's doing a really great job! At over 90 degrees outside on a sunny day, it has kept him comfortable to where he isn't sweating, and tgat isn't running it on high setting. We are very happy with it.

I bought this just before a mid 90 degree heat wave was about to hit our area in order to keep our approx 600 sg ft dog kennel cool. It worked well and kept the area at a comfortable temperature. This is so much easier to set up and use than a window mount that I would consider purchasing another portable unit rather than a window mount any day. Just remember that the portable unit does need to drain. I my case I could set it up over a floor drain , so it was easy to deal with. The down side, if you are not so lucky as to have a drain nearby, is that you may have to run a hose, use a shallow drain pan or periodically empty the unit.

My second of these DeLonghi heat pump three-in-one's. First one is a 12.5 K and still works great. This new one is slightly more powerful at 14.0 K. We're using the new one in an insulated three-car garage in Florida. Does the job..

I have a 1500 sq foot shop with 16 ft ceilings and it's amazing how well it will keep the shop at 70 degrees even on a 90 degree day outside. This unit is designed for a normal 700 sq foot area but performs at a much higher level in my opinion.

It is portable and does cool my bedroom, but I had to buy extra insulation around the window since the window didn't shut evenly. The lowest temp is 68 degrees. My room is about 700 feet and has a bathroom attached, but it doesn't completely cool the bathroom since it's not blowing directly into it. Be careful when you move the unit that the tubing occasionally comes out of the window.

I bought this about a month ago for my bedroom to work with central air conditioning to get the temperature cooler and it's working great and I am sleeping better.

Does the job. Mind the square footage and ceiling height of the room you're trying to cool. This one kept our living room at 72F or below during a central A/C outage that lasted a week.

After we got the window ready to vent the A/C unit, which took some time to make it air tight. We plugged the unit in and it didn't work. We called Delongi customer service. After speaking with them it was decided that I need a new unit. I was instructed to cut the cord and send a picture so a new unit could be delivered. That was 11 days ago. I'm not sure how the actual unit works at this point. I'm just very disappointed with the setup and slow replacement.
