Air Balancing can solve issues of hot and/or cold rooms.

However if a room is hot or cold due to the time of day (cooling the morning but warm in the afternoon), sun exposure of heavy heat loads in a room, zoning is the proper solution.

Zoning is also a great way to save energy. You would not think of turning on all the lights in your house just to read a good book by your bedside. So why would you continue to cool or heat your entire house all day long.

Zoning uses motorized dampers and thermostats to control airflow to the rooms that need it only when they need it. Therefore you only cool portions of your home as needed, saving you money.
