The catch
LG 6,000 BTU Window Air Conditioner
ThinQ phone control is not documented
Side by side
If changing settings from your phone appeals to you, take the LG LW6024RSMX. If three fan settings matter more to you than app control, take the LW6017R. Both are 6,000 BTU fixed-speed units meant for a room around 250 square feet. The RSMX is 3 lb lighter, yet it still won't cool a larger room.
Before you buy
If you want to change settings from a phone, RSMX is the fit. LW6017R has three fan settings instead of two, which helps when high feels too strong and low too weak. Neither specification proves that one unit sounds less intrusive in a bedroom.
Where this comes from
Current LG tables give RSMX ThinQ and Wi-Fi, with two cooling and fan speeds. LW6017R is listed with three speeds and an included remote. Both publish the same 57/52 dBA high/low figures, with no matched bedroom test behind them.

Phone control, fan settings, seasonal lifting and window requirements are what separate LG LW6017R and LW6024RSMX. Weigh them before you buy a 6,000 BTU unit.
If changing settings from your phone appeals to you, take the LG LW6024RSMX. If three fan settings matter more to you than app control, take the LW6017R. Both are 6,000 BTU fixed-speed units meant for a room around 250 square feet. The RSMX is 3 lb lighter, yet it still won't cool a larger room.
Which one fits
ThinQ over Wi-Fi comes with RSMX. When app control is not needed, its remote still does the job.
RSMX lists high and low, and LW6017R offers three speeds.
RSMX currently has a net weight 3 lb lower. For either unit, follow the handling and support instructions.
Current tables show equal high/low sound figures, and neither unit uses an inverter. No matched sleep-noise test picks a winner.
In practice
If you want to change settings from a phone, RSMX is the fit. LW6017R has three fan settings instead of two, which helps when high feels too strong and low too weak. Neither specification proves that one unit sounds less intrusive in a bedroom.
Current LG tables give RSMX ThinQ and Wi-Fi, with two cooling and fan speeds. LW6017R is listed with three speeds and an included remote. Both publish the same 57/52 dBA high/low figures, with no matched bedroom test behind them.
RSMX weighs 37 lb, while the current listing for LW6017R says 40 lb. That works out to 7.5% less published machine weight to handle at seasonal installation. Both still need the support and handling procedure from their manuals, especially above ground level.
(40 − 37) ÷ 40 × 100 = 7.5%. The figures are current published net weights. They are not shipping weights and do not measure installation effort.
RSMX is about 1.54 inches shallower, yet each requires a 12-inch minimum opening. Cabinet depth by itself does not tell you how far the unit projects into the room or whether a storm-window frame gets in the way of installation. Consult the mounting drawing before picking either for a cramped sill.
14.37 − (12 + 5/6) = 1.5367 inches. LG’s RSMX product page and manual give different width ranges, so the current manual’s 21 to 35 inches stays as the screening range, and the supplied unit’s instructions settle the final fit.
Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
6,000 BTU on 115V. Fits window openings 21 to 35 inches wide and at least 12 inches tall. Your room works out to 8,000 BTU.

The cooling target uses the standard room-size method, adjusted for sun, extra people and kitchen heat. The window check uses the maker’s published limits.

LG, LW6017R
Its documented sash range of 21 to 35 inches wide pairs with 6,000 BTU per hour of cooling.

LG, LW6024RSMX
Rated for 6,000 BTU per hour of cooling, with a documented sash range of 21 to 35 inches wide.
Spec by spec
| Spec | LG 6,000 BTU Window Air Conditioner | LG 6,000 BTU Smart Wi-Fi Window Air Conditioner | In practice |
|---|---|---|---|
| Controls | Panel and included remote | Panel, remote and ThinQ over Wi-Fi | With Wi-Fi and the app available, RSMX brings phone control. |
| Cooling and fan speeds | 3 | 2, high and low | LW6017R has a setting in between. That does not prove quieter operation. |
| Published net weight | 40 lb | 37 lb | RSMX takes 3 lb off the seasonal lift, but that does not make installing alone safe. |
| Cabinet depth | 14.37 inches | 12 5/6 inches, about 12.83 | RSMX comes in about 1.54 inches shallower, but the mounting drawing still decides window fit. |
| Combined efficiency rating | 11.3 CEER | 11.5 CEER | A small rating gap cannot be relied on to forecast a household bill. |
| Cooling size and compressor | 6,000 BTU, fixed-speed | 6,000 BTU, fixed-speed | Smart controls neither make an inverter nor solve a larger room. |
| Minimum window opening height | 12 inches | 12 inches in the current manual | The height requirement gives neither a low-window advantage. |
Trade-offs
Change of plan
Go with LG 6,000 BTU Smart Wi-Fi Window Air Conditioner. That capability comes from ThinQ once the unit has Wi-Fi and the app is set up.
Go with LG 6,000 BTU Window Air Conditioner. LW6017R gives you a third fan setting, so you are not forced to choose between two.
Decision guide
Phone control is the case for the LG LW6024RSMX, and three fan settings are the case for the LW6017R. Each is a 6,000 BTU fixed-speed unit for a room around 250 square feet. The RSMX weighs 3 lb less but does not cool any larger a room.
The rating for both is a room around 250 square feet. Your actual cooling load can shift with sun exposure, cooking heat, ceiling height and an open doorway. No phone app will turn an undersized unit into one that suits a hotter or larger space.
Each needs a 12-inch opening. On the width range, LG’s current RSMX page and its manual contradict each other, so measure against the instructions that come with the unit. Width is not the only thing to check. Look at sill shape, storm-window obstruction and support hardware too.
CEER ratings come to 11.3 and 11.5, a small difference on paper. Operating hours, room heat gain and thermostat use mean those two numbers alone can't support a credible estimate of household savings.
