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.

Powerful and energy efficient

Timbuk2 8/1/2022

Bought this to replace the older one I had because of its features and size. Im very happy with the cooling abilities in my Florida room with lots of glass windows which presents a challenge. This unit has the power and BTU size that really was needed for this situation. Im loving how it actually cuts off for a little while and comes back on when the temperature gets to high. Its a 400 square foot room and I set the thermostat for 71 and it maintains it very well. The only drawback is that its a little loud but its not a deal breaker. I havent put it in the heat cycle yet because its not needed. I did briefly turn it on the heat and it seems very capable.

Great FInd

Rocamix 2/7/2022

I brought this LG model about 2 month ago and I absolutely love it. The price was reasonable compared to others I checked. I come in from work and set the heat cycle on 78 and within 5 minutes my whole living room is nice and warm. It fit perfectly in the pre-cut space nice. I will purchase more for my other rooms.

Unit struggles to output 68 air when outside temp is 75. Unit is on North side of the house shaded by large tree. In hot weather Unit is unacceptable. Took repairman more than a week to arrive and claims unit is operating properly.
