    • 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

    • PERFECT
Size: 18000 BTU Style: Electronic 230V
I was wanting to rate the seller but Amazon has apparently lost their minds. Seller shipped FAST. Thank you! I bought this prior to foot surgery because I have only had wood heat exclusively, and needed a good heat source in order to stay off my feet (not need to tend the wood stove) so wounds would heal. I live in an old farm house that has ZERO insulation. This unit was easy to install and has worked beautifully for the 2 months I've been running it. It has a smooth start/end cycle and keeps the temperature STEADY (no big temp swings like cheap units) and is actually pretty efficient considering this old house. I LOVE this unit! Highly recommend! If you can afford the more expensive, larger model and have the window size for it, that model might be a little quieter. But this unit really blows the heat out and heats well. I'll assume the cooling (which I tested) will be as good at least. If this particular unit isn't so quiet (it's not bad, don't get me wrong), it's because it's a large unit that works! ... show more

    • Serves the Purpose
Size: 12,000 BTU Style: Electronic 230V
I use the heat and air system in a room that is not directly served by the central heat and air system. It is perfect for that purpose and performs very well.

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.

    • Worst experience ever!!!
Size: 12,000 BTU Style: Electronic 230V
Bought 2 of these units for an apartment remodel. One works fine, the other warms after 10 minutes running, no cold air. My experience trying to replace it has gone on for over a month with 0 results. The latest being because it's an apartment it's considered a business, not a residence!!! Where's the logic?! So not only will they not replace it, it's not covered under the warranty for repair. What does it matter where it is as long as it's in a appropriate sized room?! Bottom line, brand new product doesn't work and it's on me. And now I'm at their mercy as it's beautifully built into a window and unless I want to take it all apart and buy a different brand, I'm screwed! LG never again! Life's Good is a horrible slogan! ... show more
