A Single-Room Air Conditioner Superior to a Window Unit

At Keystone Heating & Air Conditioning Co., Inc we realize the concerns with window air conditioning units in Racine. They let flies and other bugs in. They let rain in. Worst of all, they can let intruders in. We have a better solution. A mini-split air conditioner is a more secure and more efficient solution for your single-room cooling demands.

Because of it’s ductless design, this type of air conditioner can help cool that bedroom that’s a little too warm or that spare bedroom that is hard to cool. Plus, it’s not difficult to install and is free of the possibility of complicated future alterations.
