ENERGY STAR® 2018 Emerging Technology Award1

ENERGY STAR® 2018 Emerging Technology Award

The ENERGY STAR® Emerging Technology Award is given to innovative technologies that meet rigorous performance criteria to reduce energy use and lower greenhouse gas emissions, without sacrificing features or functionality.
1. Inverter Technology is a key attribute of LG’s new room air conditioners. It is used in conjunction with a variable-speed compressor and adjusts the compressor motor speed to regulate temperature. This is more energy efficient than non-Inverter Technology room air conditioners, which turns the compressor either on or off to regulate temperature. In Department of Energy approved testing, LG’s Inverter room air conditioner model (LW1817IVSM) showed a 25% Combined Energy Efficiency Ratio (CEER) positive difference when compared with the ENERGY STAR® minimum CEER requirement.
2. The Energy Guide label estimates how much energy the appliance uses, compares energy use of similar products, and lists approximate annual operating costs.
3. The estimated annual energy cost is based on a national average electricity cost of 13 cents per kWh and seasonal use of 8 hours a day over a 3-month period. Your exact costs will depend on local utility rates and the type and source of your energy.

What people are saying
Rated 5 out of 5 by from Love the Sleep feature This is a replacement for a much older LG air conditioner. I wanted LG because of the dehumidifier setting that my old one had. I decided to upgrade to this deluxe model with the Wi-Fi control and so far I am very happy. I love the sleep feature you can barely hear this air-conditioner run. I hope it lasts as long as the one it’s replacing, the old one was over 10 years old and never gave me a problem.

Rated 5 out of 5 by from Easy Install and great wifi We installed the unit 3 weeks ago at our Florida vacation rental property. It's worked perfectly and we are pleased with the purchase. The wi-fi was simple to setup and we can monitor the unit and change the settings from anywhere.

I am looking for a quiet thru wall unit.does LG make a dual inverter they wall unit or something comparable??

Asked by: Michael z
I just had this model (professionally) recommended and installed by an HVAC company to replace a 40 year old window unit that had been instaled through the wall. In my case, the hole in the wall was already framed out like a window but with no actual window. The framing for it is sturdy and all the grills outside are free and clear. So I suppose you could do it if you have a similar framed out space for it. And it is very quiet.

What kind of plug is on this unit- a 110 or 220?

Asked by: ADAMAS
The LG 18,000 BTU DUAL Inverter Smart wi-fi Enabled Window Air Conditioner, Model # LW1817IVSM has to be plugged into a standard 240 V, 3-wire grounding receptacle rated at 15 A, 60Hz. The NEMA configuration for the plug is 6-15P (two horizontal blades over a d-shaped grounding pin)...^IFV

Will this unit fit inside a 26.5 inch wide window opening if used without side fillers?

Asked by: daveocoolguy
The LG 18,000 BTU DUAL Inverter Smart wi-fi Enabled Window Air Conditioner, Model # LW1817IVSM has a width of 26" without the front grille so it will fit into an opening of 26 1/2", but you definitely cannot use the left and right curtain panels, so you will need to find some way of closing the openings on either side of the air conditioner after installation. You also need to take into consideration that you only have a 1/4" of room on either side of the air conditioner to work with when installing it which will not be enough space to fit your hands through to hold the unit securely while installing it. The unit weighs 110 lbs and that might be a challenge if you cannot get your hands around the unit to hold is securely to install it...^IFV

I'm really interested in this unit....Can it be installed through the wall? I want to replace and existing unit that measures 26x18 approximately.

Asked by: zvocio
Your interest in the LG 18,000 BTU DUAL Inverter Smart wi-fi Enabled Window Air Conditioner, Model # LW1817IVSM is greatly appreciated. This air conditioner requires a standard single-hung or double- hung window for proper installation. It is designed for installation in standard single-hung or double-hung windows with actual opening widths from 29" to 41". The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 19" from the bottom of the upper sash to the inside sill. The outside of the cabinet must extend outward for at least 12" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner. All side louvers of the cabinet must remain exposed to the outside of the structure and other types of non-window installations, including using wall sleeves, or holes in walls are not recommended...^IFV

Why is It that when my AC is on energy saver it only shuts completely down if the temperature is set above 75. At 75 degrees on energy saver the unit continues to run never shuting off. 

Asked by: Darlene hol
Hello, Energy Saver mode is the same as Cool mode except in this mode, the compressor and fan turn off when the set temperature is achieved. Then, approximately every 3 minutes the fan turns on to allow the unit sensor to accurately determine if more cooling is needed. Whether the unit keeps running will depend on many factor suck as desired temp, room temp, outside temp, units installation and rooms insulation. ^AC

Why doesn't the LW1817IVSM come with a protective grille on the back of the unit. All of the aluminum fins are exposed? Was it just to save money? Why doesn't your tech support know what I am talking about? looks like a part is missing

Asked by: ScubaRay
Hi ScubaRay. We are sorry to hear that you are not satisfied with the design of the LG 18,000 BTU DUAL Inverter Smart wi-fi Enabled Window Air Conditioner, Model # LW1817IVSM. None of our Window Air Conditioners feature a protective grille on the back and all the fins are exposed. Thank you for your observation. We will be sure to pass that on to our engineering team...^IFV
