We Match & Beat Any Price
(Why don't we show the price?)

Retailers have the legal right to set their own prices, but some manufacturers place restrictions on how those prices may be communicated. Because our price on this item is lower than the manufacturer's “minimum advertised price,” the manufacturer does not allow us to show you our price until you place the item in your cart, or in some cases, proceeding to the final checkout stage. Taking these steps allows Appliances Connection to show you our price consistent with our goal of always offering you the lowest possible prices on the widest selection of products. You are not required to purchase the product to see our lowest price, simply just remove it from your cart.

Recommended Product:

Purchased for 4-car garage 1,500 sqft with 14` ceilings and no insulation above garage. I`ll put some insulation in later. The unit cools the garage quickly and effortlessly. It`s now nice to work on things again out of Texas summers.

Pros: Cools Quick

Cons: Haven`t been able to get the WiFi to work with Android.
