A Single-Room Air Conditioner Superior to a Window Unit

At O'Brien Heating & Air Conditioning we realize the concerns with window air conditioning units in the Main Line. They let flies and other bugs in. They let rain in. Worst of all, they can let burglars in. We have a better solution. A mini-split air conditioner is a more secure and more efficient solution for your single-room cooling needs.

Because of it’s ductless design, this type of air conditioner can help cool that sunroom that’s too hot or that media room that is tricky to cool. Plus, it’s simple to install and is free of the possibility of complex future modifications.
