What people are saying

Rated 4 out of 5 by from Room with a breeze I bought this in 2021 had it installed but unfortunately the hurricane took it out. I didn’t buy the extended warranty the first time but did this time so fingers crossed! It’s a little noisy but overall I was very happy with it, I bought a replacement the other day, I certainly hope I get more than a year out if this one. I would recommend it for sure!

Rated 5 out of 5 by from Works great; perfect fit. The unit came with a large dent in the outside shell, but I was able to get it straightened out satisfactorily, and it doesn't appear to affect any operations. The shell fit the wall opening that the old unit was in perfectly, making installation a breeze. Everything is working great. Quiet operation and the remote are real upgrades from the old unit of a different brand. I am highly satisfied.

used the heater this winter worked great for my small office. A/C does not get cold. I have it turned on to cool, but does not blow cold air.

Asked by: zolos
What is the square footage for the office that you are using the LG 12,000 BTU Window Air Conditioner, Cooling & Heating, Model # LW1216HR in? This unit has a BTU rating of 11,500/12,000 BTU which will cool an estimated area of 550 square feet. While there are many reasons why your AC might not be properly cooling your home, one of the most common culprits is a system that is too small. If the AC is too small for the size of your office, it'll keep working to reach that temperature, but to no avail because it lacks the capacity to cool such a large space. As a result, it never completes a cycle and runs continuously. You can also try cleaning your air conditioner's filter and the coils to see if improving the airflow fixes the problem. If there is ice buildup, you'll need to run the unit with just the fan in order to melt it off. If that doesn't get the unit blowing cold air again, it could be refrigerant levels are low (see below). How long have you had the air conditioner? Part of your regular maintenance should be cleaning the area around your compressor and covering it for the winter. Over the year, leaves, dirt, and other debris can build up and stop the unit from running properly...^IFV

My unit stopped blowing warm nor hot air. The anwer that you gave when asked why it's not heating, the answer that you gave was that the heating function on this unit is supplemental. A shocking answer. Please tell me the truth.

Asked by: muriithi
It should not be shocking that heating for the LG 12,000 BTU Window Air Conditioner, Cooling & Heating is supplemental heat. That is how Cooling/Heating Air Conditioners are designed. If you are saying that the heating is not working as it did before, you will need to have the unit inspected to determine what the issue is.
