    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.

    Does what it's supposed to, but too easy to break.

    otherbrothersteve 6/9/2022

    The air conditioner cools as it should. However, assembly was difficult. The plastic faceplate must be removed, and there are snap-tabs at the top which we broke off, mistakenly thinking that the faceplate should swing out from the bottom to release tabs at the top. The snaps are very, very delicate, and we snapped them all off at once. The instructions don't really tell the user exactly how the face plate has to be removed. So, I damaged a brand new product due to poor, incomplete instructions. It still cools and does what it should, but I was irked by the paucity of instruction on the manner of removing the faceplate.
