Nice Product
[This review was collected as part of a promotion.] I purchased this AC about a month ago for my living room and dining room. It is a through the wall unit. I particularly like the energy saving features. The AC is relatively quiet. It cools well. Overall, I am giving it five starts. I did buy the warranty in case I run into any issues in the next 3 years. Of course, finding a contractor to install it through the wall and an electrician to upgrade the outlet should be considered as part of the purchase process and price.
Very good product
Had a room on my house with little heat or a/c, so I could not use it most of the year. With its unit, I can heat and a/c it and use it 365. Nice product. [This review was collected as part of a promotion.]
Economical heating and cooling .
I bought this unit for an apartment we built over a garage . It's an open studio type apartment. No ducting or expensive furnace and a/c in one easily installed unit. Cost was excellent for any other heating system .
