Choose the Right A/C
Are you unsure about which Keystone air conditioner to install? If you need an A/C unit for your entire house, a central A/C system is ideal. If you just need to cool a single room, consider a window unit. Window units are cost effective and relatively easy to install. For smaller areas, such as apartments, dorm rooms and sheds, consider a wall-mounted unit to save floor space. Whether you’re working from home or enjoying an evening watching TV, you’ll stay comfortable with our high-quality, affordable products. Most of our A/C units feature different cooling modes as well as 24-hour timers. Many also come with remote controls for convenience.
