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.

Easy to use

michele03 9/23/2024

I bought my air conditioner 2 weeks ago. I am very happy with it. It works so much better than my Fredrich air conditioners. Within 5 minutes it cools my living and dining room.

Huge disappointment

Jamesoo3 7/30/2024

Sorry to say that this air conditioner died less than 24 hours after it was installed. A technician was not available for a service call for a week. It has been returned.

poor quality control

rodney wells 6/26/2024

Installed and ready for summer...

Shawnsn 5/2/2024

I purchased this unit a few weeks ago to replace the same model. The previous unit lasted several years before it started leaking. I sprayed the drain pan with flex-seal coating to delay rust and hope this unit lasts longer. Overall this is a good air conditioner and keeps the room cool on hot and humid summer days. This unit is a little quieter than previous model.

Nice wifi doesnt cool

Ohheyjesse 8/15/2023

I bought this 12000 BTU thinking it would be more powerful than my really old 10000 BTU but I was wrong. You have to walk right up to it to feel the air blowing and it doesnt do great cooling my room down. I ended up putting my old 10000 btu air conditioner in the window. This ones wifi and app are nice but it didnt offset how it didnt cool the room down. I was disappointed but the box was in bad shape when delivered so couldnt return going to end up giving it away to someone in need with a very small room to cool.
