What People Are Saying

Rated 1 out of 5 by from Not worth it. I've had 2 different models (120v & 240v) from LG and they both broke down with in a year. If the heating element goes out and you have it running on automatic it will work harder to try to bring the air temp up, which will triple your electric bill! The AC part works fine, but the heater just isn't strong enough for any lasting usage. Since I bought the unit specifically because it was a combo AC/Heater, the heater not working is a complete deal breaker.

Rated 1 out of 5 by from This product is not dependable. I purchased this item in 2008 with a five year warrenty. It broke down every year at the worst time. Either at the hottest or the coldest of weather. It is not dependable. After everything had been replaced--we actually got one year without a repair but has started all over again. Company was not helpful. If you like repairs then it is for you.

Rated 5 out of 5 by from Excellent AC unit This is in the living room of our guest house and is so powerful, most guests don't need to turn the one on in the bedroom. We haven't used the heater part but I'm confident it will be great.

Rated 5 out of 5 by from This unit is quiet and powerful I recently purchased the LW1213HR to heat and cool my 450 sq. ft garage which is fully remodeled as a work out center. I live a Florida and it gets very hot, this units cools it down in 4-5 minutes and keeps it cool and I cannot even tell a difference in my electric bill and I use every day. The heating function works just as well. Very quiet, does not interfere with the work I do with my fitness clients

Rated 5 out of 5 by from Very good product for the money! I bought this product to go in my newly constructed "Man Cave". I have been very pleased with the performance of this product. I love the fact that I can set the timer and it will come on before I get home and it will either be nice and cool or warm when I get there. I would highly recommend this product to anyone!

What wire do i need to wire the outlet?  Will 12-3 be sufficient with a 20 amp breaker

Asked by: Chipster
The LG 12,000 BTU Heat/Cool Window Air Conditioner with Remote, Model # LW1213HR has to be plugged into a standard 250V, 3-wire grounding receptacle rated at 20 A protected by a 20 Amp. time delay fuse or 20 Amp circuit breaker. It already has a power cord attached to it (NEMA Configuration 6-20p) which also has a current interrupter device attached to it. You will need to check your building code to determine what type and size or wiring or gauge you need for your outlet or check with your local building inspector...^IFV

My clean filter light wont go off what do I need to do? Is there anyway to reset it

Asked by: Cajun348
This flashing red indicator light is a normal operation for certain models. On some newer models, the POWER INDICATOR will begin to flash when it is time for the air conditioner filter to be cleaned. It is possible to reset this indicator light by unplugging the unit for approximately 3 minutes, and then restoring power to the system.

We are using the heat in our unit. It snowed and now it's making a rattle noise

Asked by: Lferdna
We regret the trouble you have experienced with this air conditioner. Snow will not cause a heater to start rattling, but if it gets into the cabinet, and into the fan, and potentially starts developing ice near the fan blades, then this could cause such a sound. It is partly for such reasons that the installation material recommends an awning installed over the air conditioner cabinet.
