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.

Do Not Buy

DaveR940 5/21/2024

AC and heat ran good for a couple of years then issues started. Unit froze over I defrosted and cleaned coils. A couple of weeks later froze up again and compressor wouldnt shut off at all unless unplugged. LG chatbot support was zero help and even managed to waste an hour of my time. $800 garbage Stay Away from this AC

terrible unit

garycar 3/4/2024

ac only a few years old and already giving problems. compressor will not shut off unless you unplug from wall. To spend over $800 on equipment you would expect to get more than a few years use. Now home depot stopped carrying unit. I see why
