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.

Purchased this unit for my hunting cabin which had a less than satisfactory 18000 BTU GE Although insulated we only could maintain a 20 degree delta. When outside was 100 inside was 78 tp 80. This unit has an excellent air volume and has been able to maintain 74 when outside is 107. Have seen a number of reviews identifying performace issues and at this point we are well pleased with this unit.

I love the wifi feature and the ability to control it from my phone. I did have technical issues within the 1st 2 months reached out to get it repaired but no one ever came out. LG customer service replaced my product. LG Customer service is the best hands down.

Worst mistake buying this unit.

Marc Mc 11/3/2021

We purchased this window air/heat unit in July 2021 and it worked for 3 weeks and stopped blowing. A repairman came 2 and sprayed WD-40 on the blower and it blew for 3 days. I requested another warranty repair and a new repairman replaced the blower. The air conditioner is working but now the heater is not working and its 58 degrees outside. Im requesting a repair now.
