    • After 3 decades this stopped my propane for heating!
Size: 8,000 BTU Style: Electronic 115V
The media could not be loaded. No assembly required btw This is a A+++ ccu unit I call it . Climate control unit. Because In a few minutes you can easily go from heating to air conditioning back to heating in moments again . Isn’t new technology as a kid I lived with a heat pump but that was thousands included in house payments . So this absolutely makes a home of recommendation 350 sq feet totally comfortable in moments. I’ve been looking for anything but propane to heat and going back to the grid isn’t in my plans ever so this fit the situation. Only using 1280 watts of continuous usage is outstanding! Not running heat side from Solar today and don’t foresee it but works fantastically with my 1600 watt generator. Saved propane most likely will cover extra fuel used for generation but no electric bills is my main goal . Not going un noticed btw Last visit from them three days ago rechecked the line They don’t understand the outstanding efficiency of this new found treasure , I dreamed about turning this sorta air conditioner around as a kid so seeing it happen I had to save the under 500$ and buy it and so glad I did wow . I have a situation going on here whereas my neighbors have been really polluting my air so with propane had to have ventilation and loss efficiency and never was a fan of the gas fumes . Again with this new ccu I don’t have to do it’s recycling air saved us from the ongoing air assault's. So win win win Another good discovery this air conditioning side uses 575 watts same as the unit I replaced but this is 50% higher cooling capacity yet uses same wattage so was delighted it runs off my Solar in perfect conditions while suns out between 11/4 most of the year in Florida off the grid btw! Why they are not happy lol But nothing but good things so far One noteworthy issue I learned with using a parallel system with Solar was that the wires must be a sizable distance between power sources because just the magnetic sine waves can Interrupt the generator and cause a glitch which a kilowatt meter picked up with flashing screen indicating a issue with power source so keep in mind to use conduit and properly space opposing power supplies . So to review ac side uses 575 watts Easy to run off the sun in perfect conditions 1280 heat pump side that I don’t see Solar powering overnight unless you’ve built a massive battery bank see a electrician or get a backup generator as I wrote about in my book Solar Independent Utility Systems Manual So conclusion far better than burning anything for heat only thing that would beat this is a properly sized radiant heating system that uses the suns heat alongside its photovoltaic advantages. My next goal with geothermal alongside to replace this but until that dream happens This is my answer for the foreseeable future Can’t say enough about this outstanding ccu No more propane tanks running out No more feeding wood fires Now just time the generator usually five to eight hours depending on your temp setting. Set it to max 86 Max cool 61 makes working much harder far safer Thank you LG You hit this one out of the park Pure awesomeness Quietness a BONUS !!!! ... show more

I installed in through the wall (stucco) in my garage and it worked very well. It is cooling 400 sq ft with no problem. The heating is not that good though.

    • Good but initially sucked to install
Size: 7500 BTU Style: Wifi 115V
We just got this in and as some other reviews alluded to, this unit is SUPER cheaply made. We had a horribly hard time getting the inside out from the cabinet because of a manufacturing issue on the back of the unit. Once we got it out, all our effort in removing it from the cabinet completely shredded the padding inside the cabinet. I then began to add the black clip on feet to the unit.. and guess what. one went in and the other broke in multiple pieces. We have not even finished setting it up yet either!!! We need to use the unit so will keep it, but be warned... The price is probably for the wifi and nothing else.. huge upsell and may not worth it! NOTE if the power goes out you may have to manually start thr wifi again, it was not automatic for us and their is a certain button combination to push to re enable wifi... which I had to guess because I could not find it in the manual! ... show more

Once we got the unit installed and turned it on we were ready for some cooling. We were not disappointed. The unit puts out a welcome stream of cold air!

    • Very loud and Noisy
Size: 18,000 BTU Style: Wifi 230V
I am extremely disappointed in this LG air conditioner. It is extremely loud and noisy. It only has 2 fan speeds. this is a disgrace for an 18,000 BTU air conditioner. I bought this because I live in an apartment that has no thermostat to control the heat level. I have 3 tower heaters used in both bedrooms and my living room. This unit also is a 12,000 heater. I thought that this would be good for my living room, dining room, kitchen and hall way. I ordered this to replace my 16,000 Frigidaire which died. it Lasted 12 years. My air conditioner is installed in a through the wall sleeve. Because of this and the weight of the unit I'm stuck with it. It is too heavy and box to return. other wise I would. Don't make my mistake. LG makes great TV's, but not great air conditioners. Buy another brand that has made air conditioners for years. ... show more

Had a difficult time finding one locally with the heat feature on it. Found this on Amazon for a good price and delivered to my doorstep. What a deal? Will be buying a second one.
