    • After 3 decades this stopped my propane for heating!
Color: White Size: 1 Count (Pack of 1) 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

    • Questionable reliability.
Color: Bright White Size: 24000 BTU Style: Electronic 230V
Was perfect. For 32 days. 2 days after pasting maximum return date it stopped blowing cold air. No leaks, no damage, no blockage. Seems a bit pricey for something that cant reach 2 months. For the price, defective units should be rare. Alost feels like it's rigged to break after the return date. It was installed properly as my friend is a licensed handyman who excells at his job. We even wired up a custom 240 for it. Everything checked out perfectly. The compressor still comes on, now it blows cold air out of the back instead of the front. Asked about what that was happening, they asked if I installed it right after saying it worked fine until the morning hit. Didn't freeze up or anything, just stoped working. Doesn't make any sense. ... show more

    • Easy to Use, perfect for cooling or heating and works on regular household 120 current.
Color: White Size: 8000 BTU Style: Wifi 115V
I own Tecopa Palms Thermoplastic Hot Springs Resort located on the Southern edge of the "very hot" and sometimes "cold" Mojave desert. I bought 2 of these ac/ heater units - 2 years ago and installed 1 in each of 2 cabins. Perfect. From cold to hot they are the real deal. The control panel is easy to understand and easy to press this button for heat, or press this button for cold, and this button up or down for temperature. These units do not take a " senior electronics engineer" to figure out how to work the panel. I recently ( this review) ordered a 3rd unit. I installed it in a sea train renovation that we rent out. ... show more

    • Perfect fit!
Color: Bright White Size: 8000 BTU Style: Electronic 115V
This air conditioner fit the bill for me. I was replacing a 22yr old through the wall a/c. This was the exact same size as the one that I was replacing. As a matter of fact the look and controls are almost the same. The difference is that this a/c also provides heat. I was able to remove the old one and replace it with this one with no modifications to the wall. This a/c is more quiet and was much needed. I would recommend this product for its features and quietness. ... show more

Color: White Size: 1 Count (Pack of 1) 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
