What people are saying

Rated 1 out of 5 by from Don’t buy We purchased this unit in June 2019. We used it a few times & then went to FL for the winter. When we returned in June 2020 we turned it on. It cooled 1 time & then quit working. An LG repair person said it has 2 leaks & would cost as much to repair as to replace. Obviously we will not replace with another LG product. We are very disappointed with this product. As far as we are concerned it is a piece of junk.

Rated 1 out of 5 by from Broken after 1 minute Bought it one month ago. Ran for 1 minute before fan failed. First repair visit unable to fix. Next visit from a different tech should happen soon? Approaching 4 weeks with a failed unit.

Box says installation kit included. Does that mean the sleeve?

Asked by: Just me now
The Installation Kit for the LG 11,200 BTU 230v Through-the-Wall Air Conditioner with Heat, Model # LT1237HR does not include the Wall Sleeve. The Wall Sleeve is an Optional Accessory and your can purchase the LG Thru-the-Wall Air Conditioner 26'' Wall Sleeve, Model # AXSVA1, the LG Wall Sleeve with Stamped Aluminum Grille, Model # AXSVA4. The LG Stamped Aluminum Grille, Model # AXRGALA01 can also be purchased for the AXSVA1...^IFV

My LT1237HNR did not come with the wall sleeve. Is the AXSVA4 sleeve the correct one for me to use ?

Asked by: IN003

Does this require a Wall Sleeve? I have a wall with hole from previous unit of 24.0 by 16.0 will this unit work in that?
