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.

Doesnt work half the time

RockD 6/27/2022

AC model LW1816ER often doesnt blow any air at -- not even warm air. Ive unplugged it for 10 minutes cleaned filters tried everything. Was working on and off and now doesnt work much at all. I have two of the exact same units. One has been a constant problem for more than a year and now second one starting to have same problems.

Most Powerful A/C Ever

TimAndVicky 8/17/2021

After an extensive heat wave we purchased this air conditioner based upon its ease of installation simple controls and the BTUs necessary to cool our house. Are we ever glad we chose this unit because within 3 minutes of turning it on our house was essentially cooled down to the right temperature. We felt alive again feeling all of that cool air seamlessly entering all the rooms with ease. The controls make it simple to use as a dehumidifier when you just wish to dry the air out too. A red light comes on when the filter needs to be cleaned which is also an easy task. If I could give 6 stars to this A/C model I would.

Mapper 6/29/2021

Bought this air conditioner a couple of months ago and we are very pleased with the performance. It cools our house very quickly amazing. Installation is not easy because it weighs so much. Wish that they offered a kit to install on vertical sliding windows.
