• We all know that with a central air conditioning system the air comes out of vents that are in different rooms in a house, and we also know that there's an air filter somewhere in the house that needs to be changed regularly.

    Did you know the air conditioning vents are located in precise places? Did you wonder why the thermostat is located in that hallway, or why two story houses usually have two air conditioning units? These questions and others are easily answered, and can empower people with some of the basic knowledge necessary to maximize the life of their central air unit.
