    • After 3 decades this stopped my propane for heating!
Color: White Size: 7500 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 love having one unit that does both heating and cooling. The AC cools efficiently and the heat warms the room faster than expected. It’s perfect for bedrooms or small living spaces. Controls are easy to use and the remote is a nice bonus. Very happy with this purchase.

    • Defective and broken
Color: Bright White Size: 18000 BTU Style: Electronic 230V
It took two of us to even remove it from the shipping carton, as it was very heavy. It had obviously been handled quite roughly, probably during shipping. The fins/ condenser blades on the front were badly damaged, but the most surprising thing is the big fan blades were broken into about 4 or 5 pieces, and they were made of a very cheap plastic....I couldn't believe this was an LG product. Shoddy ,cheap manufacturing that they obviously hoped no one would see ,being on the inside of the large metal casing. Since the casing came out separately though, fortunately the damage was the first thing we saw. We learned a lesson to not get anything of this size through Amazon. We were told there were no replacements available. And we'd have to take a refund. After seeing that the large fan blades were made out of plastic, we had no problem to choose this option.. Those blades would not have lasted but maybe 2 or 3 summers in Texas heat, and would have become as brittle as glass. I'd advise you to stay away from this model. ... show more

    • Heating AND cooling in the same unit - wonderful
Color: Bright White Size: 7500 BTU Style: Wifi 115V
I got this to replace the Vornado space / small room heater. This unit has not only a heater built-in but also air conditioning! It makes a wonderful addition to the mancave shed. It is very energy efficient, and it didn't significantly increase our electric bill. It fit in a semi-narrow single-pane glass window. We had to get a special mount for it so that it could be bolted into the windowsill, but regardless, we love it. We have it on auto all the time, and we've been satisfied. It does the job. ... show more

    • Best investment LOVE THIS
Color: White Size: 7500 BTU Style: Electronic 115V
Let me start by saying I'm in florida. It has to be something powerful to cool us down. This device is on a poorly insulated front porch. Wow wow wow. She cools to the cool setting. Cycles on and off. For the 10 days a year were cold She heats it up not just takes the chill out, but heats it up. (Were not blasting it to 90s but a goodb73 will do. It cycles on and off keeping the room comfy. Not to much 1 way or the other, or some craziness that needs a babysitter. No more noisy than any other ac. Tells you when you need to clean the filter, and it don't lie. I found and ordered this ac here on Amazon. I swear on all that's good prior to it's arrival, I seen the EXACT same machine for DOUBLE in a big box store I'm happy I kept my order The only 1 thing for people that's like me. I'm not a handy man. It is a bit heavy. My son built a deal to help hold some of its weight off the back All in all we couldn't be happier with it. I can't say on if it did anything to my power bill. We were leaving the door open previous trying to make the house ac cool and the house heat warm it. And the same time we put that in we also put in a mini fridge so I'm not sure our bill changed much. ... show more
