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 and 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.

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

Works excellent

Submitted by Kimichangas - 7/4/2021

This thing is a beast A quiet beast :. It puts out a ton of cold air and is even quieter than Id hoped. It was easy to install. I love the remote - makes it so easy to control the temperature from afar. Its definitely saving me money on the electricity bill since I can cook the part of the house its in and I can keep the unused rooms warmer. I love this thing

Great AC/Heater Combo

Submitted by Ry Whisky - 6/13/2021

I just installed this on my hunting lease trailer and this thing is perfect Installation wasnt difficult and its such an upgrade from the one we had before. Its warm already so I didnt try the heater but the AC runs nice and cold and cools down the space beautifully. I cant wait until hunting season when I can adjust the heat levels from my phone without getting out of my bed. Overall Im extremely happy and would definitely recommend it

Fantastic Product

Submitted by ajhaus13 - 6/7/2021

We got this to heat/cool a decent sized room and it works better than we could have imagined. The ability to control this via wifi is one of the best features on this. Preheating/cooling a room before entering is amazing

Excellent unit

Submitted by Nonisey - 5/30/2021

We placed this unit in our mid size work shop/tool shed. Being able to control the unit from anywhere is going to save us money. I can now turn it on and cool or heat the shop before I get in there to work. I also appreciate having a washable filter. This was a great choice that really suited our needs.

So whisper quiet

Submitted by MommyBear - 5/30/2021

This unit has been a lifesaver in the Florida heat. It runs smoothly and efficiently and isnt loud at all. And you can control it from your phone How awesome is that? The app could use a little bit of work but the unit also comes with a remote

We love this air conditioner

Submitted by Selbyray - 5/28/2021

We installed this LG window unit in a window in our living area. I will use it when the lights go out during the frequent summer storms/hurricanes we have here in South East Texas. I tried it with my portable generator and it starts up and operated very smooth as if it were on the grid. It is just what I needed for emergency situations. It cools our big 15x 17 living are very well. We also like the remote control.

Easy to install/works great

Submitted by Texxasgurl45 - 5/28/2021

First of all this was very easy to install. It even came with the window installation kit. Next I love that its not super noisy like the other window unit we had. I love the fact I can control it from my smartphone as well. Super convenient and just awesome- probably one of my favorite features. Its so cool that its not just an air conditioner but also a heater. My husband installed it in his man cave because it tends to get either a little too warm or cold during the winter. This is just what he needed-a heater and air condition all in one. It cools the room perfectly and doesnt take long . The heat feature is amazing too. Gets nice and toasty in a jiffy Just an overall great unit for any room Works great and is multifunctional.

Loving it

Submitted by La Nena1 - 5/27/2021

We were looking for a new A.C to put in our garage and I am excited to keep using this one. We have tested it out to see how the air flow is and it gets quite cold. We had to wait a about 15 to 30 minutes to feel the cold flow due to the fact that we live in a hot state and we did put it in the garage. This one is great for a small to medium room. I have had no problems with it at all. The size is perfect for a small to medium window. This one also work with wifi and it brings a controller so you dont have to keep getting up. It is easy to clean and the best part is that it is not loud. This is the first time I get a LG A.C and I also like the feature that you can us it as a A.C or a heater

Awesome Product

Submitted by Designgirly - 5/25/2021

I have really enjoyed using my LG Electronics - LW8021HRSM - Room Air Conditioner. This is a great room air conditioner that works amazingly well. Installation was very easy and it came with its own window installation kit. I especially like that this unit also provides supplemental heating. This product has so many great features but some of the best are the different heating and cooling speeds the convenient electronic controls and the awesome smartphone control. I highly recommend this product to anyone looking for an amazing room air conditioner because this LG product is truly amazing.

Perfect heating and cooling

Submitted by Kaylynn11 - 5/24/2021

So easy to install and i love that it heats and cools This is my first window unit that heats as well and i will never go back to one without heat. This one blows strong enough to get the room to the temperature i want it fast. I also love the bonus of having a remote to control it so no more getting up and down any time it needs to be adjusted

My garage is now habitable in summer.

Submitted by UK Mark - 5/24/2021

I used this LG A/C unit in my garage which until now has been too hot to use as a workshop in the summer despite using foam insulation panels on the inside of the door. The 320 sq ft recommended maximum cooling area was perfect for my requirements and I can now work on my bicycles for an extra 4 months of the year rather than use the kitchen and annoy my wife I love the smartphone feature which makes it really easy to use and the clean modern styling. I own multiple LG products and have always trusted the brand to be the best available. It is also pretty quiet considering it is a window mount unit which in my experience of motel rooms over the years tend to be annoyingly loud. Very straightforward to fit with great instructions included. I love the fact that I now have an extra useable room for the summer - Texas can get pretty hot from June through September. Not the cheapest unit out there but well worth the money in my opinion.

Best AC unit for any room

Submitted by aclarkson2013 - 5/24/2021

So I am not sure if I am the only person who did this but I built my wood working shop with this AC unit in mind. I have and 550sqf shed that gets up to 120 degrees but not anymore. This AC unit cools my shed with in 5-10 mins. Makes little noise and is easy to use. The best part about this is its I can control it from my phone so I dont have to worry about going to the unit every time to change something on it. If you have a work shop of any kind you need this AC unit.

Heating and Cooling

Submitted by eddierey - 5/20/2021

This LG is a window climate control unit. Its not just a cooling unit but also provides heat. I have an office that is situated in an addition to an older home. The people that did the addition didnt pay too much attention to the air conditioning and heat for the added rooms. Living in Texas that is a big mistake. My office is cold in the winter and hot in the summer. This unit has already proved useful in taming some 90 degree days and I expect it will be even more useful when the temperature gets to 100 soon. I am also expecting it to provide a more comfortable work environment in the winter. It supports Wifi smartphone controls so you can adjust the temperature before you enter the room or even when you are away from home and it has an intuitive built-in electronic control pad. Its pretty efficient for a window unit - 11 CEER Combined Energy Efficiency Rating.

Smart product

Submitted by Jbtextex - 5/18/2021

This is my third LG item that I control from my phone using the ThinQ app from LG first and second being my LG washer and dryer. Installation was easy and the unit looks classy not to mention that it works well all features and silently. The sound is minimal for all the work this unit does. Im so impressed and may just get another one
