Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Great unit

Cathy Lynn 4/4/2024

My husband built me a sewing room behind our house and installed the window unit to keep me warm in winter and cool in summer. It works great. I use the app on my phone to turn the unit to the desired temperature before I go out to work. Love it

Tiger1827 11/7/2023

This unit was easy to install. Operation is generally uncomplicated and serves our purpose. Heating our living area was the feature we were most interested in. Im confident the AC will be just as efficient.

Cools down the whole room

Milag 9/26/2023

When our ac went out this was a life saver . We have a decent sized living room and it kept it nice and chilly to combat the Texas heat and it even extended into the kitchen well too. Its powerful and not crazy noisy like some window units tend to be. Was very happy and thankful for this unit . Also like how it can turn into a heater for the winter will be great to use in the rv for our winter fishing adventures

Quiet and efficient

ThePies0425 9/9/2023

I purchased this window AC to replace or old air conditioner. After having purchased a LG refrigerator- I knew our new window AC would be LG also. Its quiet and works well in our small home. The energy saving feature is my favorite setting. I cannot wait to see how the new AC impacts our electric bill. We saw a significant decrease after we bought our fridge. And were already talking about buying a new LG stove/oven. Cant wait

Top-Notch Cooling Performance

AaronCh 8/22/2023

Im absolutely thrilled with my LG 7500 BTU window unit air conditioner. Its a powerhouse of cooling in a small package. It cools my room down quickly and effectively making it a lifesaver during hot days. The setup was a breeze and I was pleasantly surprised by how quietly it operates. Not only does it keep me comfortable but Ive also noticed a positive impact on my energy bill. I can confidently give it a well-deserved 5-star rating

Great ac

Lobab 8/11/2023

I purchased this ac a couple of weeks ago. The ease of installation and use is terrific. Cools nicely in our 108* days here in south Texas. Also being a heat pump it will come in handy for our cooler days a little further into the year when winter finally comes.

Great unit

MsChucky15 6/10/2023

I bought this unit about 3 weeks ago and I love it It really puts out like I did on prom night. It replaced our hvac and it cools about 1200 square feet which is equivalent to a normal size living room hallway and a large bedroom. We keep it on 73 because it gets too cold when were in the same room with it. It can be turned on through the app which is very convenient. We turn in the ceiling fan to help circulate the air. Great purchase

LG AC Review

M Carroll 6/6/2023

I bought this to replace a fifteen year old unit. Old unit different manufacturer was extremely loud so I bought this based upon decibel rating plus the heat capability and it was the same size as the old unit making installation easy. We are extremely pleased with the performance and quiet operation. We have purchased many LG products over the years with very good results.

WIFI STOPPED WORKING AFTER A YEAR

TRH2000 1/25/2023

I bought the LW1221HRSM the LW8021HRSM in July of 2021. They were purchased because they had WiFi and I could turn them on remotely when the temperatures were below freezing. They would sometimes lose their connection but I was always able to reconnect them. In November 2022 they lost WiFi before a severe cold front making them basically useless. They will not connect because the network connection is unstable. LG has admitted that they are having issues with the LGEwhisen network but they dont have any solutions. I am furious that I wasted money buying these and they only served their purpose for just over a year. I have several other LG products and have always been satisfied but these are making me rethink any LG product

Ac compressor will not turn off

Tysons dad 12/31/2022

The ac blow ice cold and the heater doesnt blow hot after inspection I noticed the ac compressor is not turning off when the heat is on and its staying on even after you turn the unit off. Only way to get the ac compressor to turn off is to cut off the power to it by either unplugging it or tripping the button on the plug. LW8021HRSM This is my model number. The unit is clean and not stopped up.
