Rated 5 out of 5 by from Best Little AC/HEATER Unit ever!! My wife found this unit on Amazon and bought it because it is a very reasonable in price. We bought two actually. Today they are in our newly built garage office spaces. They work great!! I've already recommended it to two people.

Just bought and installed. The heat blows only cold air. What's the problem?

Asked by: Nothappynana
The heater for the LG 7,500 BTU Smart Wi-Fi Enabled Window Air Conditioner, Cooling & Heating, Model # LW8021HRSM is intended to be supplemental heater, not the primary source of heat. You can test the heater by taking a piece of paper and placing it in front of the air intake grille while the unit is running in heat mode. The piece of paper should get pulled up to the grille. Once it is, place your hand at the air vent to see if the air begins to heat up. If so, the heat function is working. If the unit does not seem to be heating up well, it may be excessively cold outside or your room may not be heating well. If the air coming from the unit does not heat up, the unit will require service...^Ivan

I’m looking at getting the LW8031HRSM A/C & Heater but I’m wondering about the installation. Will it work on a horizontal sliding window and how do I measure to confirm it  will fit. Does the sliding portion of the window come out?

Asked by: Stenz
The LG 7,500 BTU Smart Wi-Fi Enabled Window Air Conditioner, Cooling & Heating, Model # LW8021HRSM is not designed for installation in horizontal-sliding windows. It is designed for installation in standard single-hung o double-hung windows that have actual opening widths from 22" to 36". The top and bottom windows sashes must open sufficiently to allow a clear vertical opening of 14" from the bottom of the upper sash to the inside sill...^Ivan

When this unit is on ac mode where does the water leak out from?

Asked by: Sassy123
When the LG 7,500 BTU Smart Wi-Fi Enabled Window Air Conditioner, Cooling & Heating, Model # LW8021HRSM is in AC Mode, the condensate that drips off the evaporator coils collects in the base pan at the bottom of the unit which is why it is recommended that you install the cabinet with a slight tilt (about 1/2") downward on the outside. The unit is equipped with a slinger fan that has an outer ring that picks up the condensed water from the base pan if the water level gets high enough. The water is then picked up by the fan and expelled through the condenser, making their conditioner more efficient. In humid weather, excess water may cause the base pan to overflow. To drain the water, remove the drain cap and secure the supplied drain pipe to the rear hole of the base pan. Press the drain pipe into the hole by pushing down and away from the fins to avoid injury...^IFV
