Review: After 3 decades this stopped my propane for heating! - 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 !!!!

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.

### ⭐⭐⭐⭐⭐ Heating AND cooling in the same unit - wonderful
*by A***G on September 24, 2025*

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.
