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.

Cools Beautifully

Lyn74 9/13/2023

We purchased this air conditioner couple of weeks ago. It is Big and beautiful. It cools beautifully but one of the faults I have is the snapping sounds it makes when it kicks in and out constantly. It is in our living room where we both sit and it constantly clicks and clicks. The second fault is I cannot adjust the vents. I originally got them to point up but I cannot move them down Im afraid they will break theyre that tight. Otherwise its great.

an exact fit

Girl from Ipanema 8/15/2023

This unit is quiet and cools one room to cold and doesnt distribute the cool air like my previous unit. The energy efficient newer units are not cooling efficiently unfortunately

Everything I expected

EisenBison 6/17/2023

I purchased this using it to cool a walk-in cooler for our vegetable production. Since installing it I havent had to worry about vegetables spoiling in the summer heat one bit. The AC unit runs quietly and efficiently and Im always surprized at how cool the cooler is

Defunct unit and no response from customer service

Returning unit 5/24/2023

Bought the unit and had my contractor install it. The unit turns on and the fan works but when the compressor kicks on it immediately shuts down with a strange noise. Have been waiting 20 days after 2 contact attempts for a service repair. I will now return it to the store and get another brand.
