How to Measure a Window for an Air Conditioner

Adding a window air conditioner to your home can help cool a specific room without having you completely overhaul your home air-conditioning system. When selecting a window air-conditioning unit, you will need to select a window that will fit the unit.

If the room that you desire to cool does not have an appropriate window, you may need to select a wall air conditioner.
