Testimonial

"I'm in love with this thing! Should have got one a long time ago. I live in a one-bedroom apartment in a building that was built in 1920. So needless to say there is no central air. I do have one small window unit that came with the apartment at one end of the apartment. Which means, the other end of the apartment (which is my bedroom) is always hot. I bought this instead of another window unit as I don't plan on living here forever. When I move, I take her with me . This was the best investment I've made in a long time. No more hot summer nights here in the south for me. Yes it is a little noisy, but no more than a normal window unit. Doesn't bother me much. I'll take noise over hot sweaty nights. I totally recommend it" - Janet

Testimonial

"Love the design and the compactness of this unit. From reading the other reviews, I had horrible thoughts of it's weight and being hard to maneuver. It isn't. It's on wheels. It rolls around easily and cools the area needed." - Terry

Testimonial

"I am very happy with my Honeywell air conditioner/heater. It works great so far and has made living with the heat more bearable this summer. There was a mix-up in shipping and I was originally sent the wrong model but Amazon corrected the problem right away and other than difficulties dealing with UPS and scheduling the return pickup, all turned out well. Set-up was easy and my large, open-concept living/dining room was a lot cooler in no time." - AC

Testimonial

"This portable air conditioner works perfectly in my own room. Once the AC was arrived , I can’t wait to install it because my house temperature was not even. My room is farther down the hallway , so my room is always hotter than any other rooms. If I turned it down the ac then other complain too cold . So , I decided to have my own additional Portable AC to put in my room. This AC is very easy install and comes with a remote control to adjust the temperature. Not too noisy and very convenient to use. The little down side is you probably have too dump the water often . But it’s all right , all I care is cooling in my room and relaxing." -  Peralta

Testimonial

" I was born and raised in Houston and yet am the worst diva when it comes to heat. Heat and I don’t do well together. Anyway, I still live in Texas and needed this ac unit for my garage to make my peloton workouts bearable. This little guy cools down a super Texas hot garage very quickly, earning 5 stars from this heat diva. We have a super annoying HOA so I just open the window and insert assembled pipe in the window sill when I workout and simply remove from and close window when done. Very easy to use and even has a remote! This product has done more than cool my garage, it has helped me be more active at home!
I would 100% buy this product again!" - Anonymous

Testimonial

"I live in Tampa & purchased this unit for an emergency back-up system for storm/hurricane power outages and I also own several residential rental properties which all have central AC including my primary residence. I recently had a AC compressor blow up and had to use this unit for about 5 days until a new central system was installed. It worked great, blew nice cool air and kept a 20’ x 15’ room very cool, the noise level is reasonable, it’s not super loud or super quiet. I highly reccomend this LG portable unit for a temporary AC supply. I rate it 4.5 stars out of 5..
PS- I have only had it for 30 days, so I do not have a long term time line of use data yet." - T Miles

Testimonial

"Easy setup, pumps good amount of cold air. Only thing is with the drain - claims say it evaporates 98% of moisture thru exhaust vent. I call bs on that part. There is an option to move the unit to a drain or outside and pull the plug (which I did the first time) and about 12 oz came out. Realized the internal pan is quite small. I needed this to run 24/7 without shutting off due to full drip pan. I grabbed an old washer drain hose and cut it to about 18". Let it drip into the 4 gallon Home Depot bucket setting next to the unit. It will fill that bucket on Low setting in about 2-3 days, depending on how hot it is. Much easier to carry a bucket out every couple days than in hooking the unit from the window and wheeling it out every few hours." - JM Wood

Testimonial

"I use this to cool my finished, dormered attic. The central A/C on my old bungalow can cool the rest of the house ok, but it's not quite large enough to cool the attic too. So I shut-off all the ducts to the attic, and installed this up there. My attic is probably 25'x50', and this unit handles it just fine. I also didn't need to install it in the window, on a support bracket, as the in-window units require. Pretty easy. And way, way cheaper than installing a second central A/C unit, or replacing the existing central A/C unit with a bigger one." - Scott Tucker

Testimonial

"Great unit. Easy to set up, but DO have some Duct tape on the ready. The window fitting you will find, is not a universal fit because of the shape of the exhaust tube window fitting. Fits mostly well, but you might still need the help of some duct tape. It's really not a big deal, the tape will actually help keep the unit anchored to the window, and hot air from leaking in/cold air from leaking out. Make sure you set up the vent on the inside of a screen to keep the bugs out. If your choice window doesn't have a screen, buy a small piece at the hardware store and place some on the face of the hot air exhaust. Speaking of tape, the BEST way to use the foamy adhesive tape that comes with the system, is by throwing it away altogether. It sticks well 1 time, but if you need to correct it or when you're ready to remove it, it falls apart to smithereens. Again, just use the weather proof Duct tape and you'll be good to go. The unit cools very nicely right out of the box. DO pay attention to the instructions if you want this little power house to last, working well, and from getting moldy. Definitely designed for small rooms, about 350-400sq feet at most, sparsely furnished and with low ceilings. I do wish I could prop it up somewhere for it to be above head level, as all cold air machines should be. It's just not designed that way, but IF you are somehow able to prop it up and make sure it doesn't roll off on your kids' heads, then you're golden! We're using it on a temporary basis, while our A/C dances in and out of service, until I can get back to work and pay to have it looked at." - Vanessa

Testimonial

"This is an overall excellent product. Easy to install, very quiet, works great, looks good. What else could one want. Would give 6 stars if allowed.

One caveat--I had trouble with condensation issues. The piece that came with the unit that is supposed to fit on the spout attached to the unit came was damaged. Called customer service, and they kindly offered to have a new part sent out when available. Instead, I came up with a simple work around: got a 2 foot long 1/2 inch vinyl tube from the plumbing department of my local hardware store and a small bucket. Slipped the tube right on the spout and placed the other end in a small bucket. Fix cost: under $5. Time involved once the parts were acquired: less than 2 minutes." - JKS
