Top 6 Rules For Designing A Zoning System

Last updated 2 years ago

The best way to make sure all the rooms in your San Fernando or Santa Clarita Valley area home are comfortable year-round is to make custom zoning part of your home-comfort system. But designing a zoning system to fit your specific home and its layout is crucial.

Because zoned systems use a set of dampers within your duct system to direct cooled or warmed air exactly where it's needed in your home, your contractor should follow these guidelines for maximum results: 
 

  1. Include no more than one floor per zone. The second story must be zoned separately, because its needs are so different. Hot air rises and the upstairs will naturally be warmer, so in summer, for example, more cool air will need to be directed up there than to the downstairs.
  2. Only one construction type per zone. New additions often have different air conditioning needs than the rest of the house, since they're likely to be more airtight. A new area or room needs a dedicated thermostat to operate independently. 
  3. Internal rooms should be combined into one zone when possible. If there are no external walls in the room it won't be as vulnerable to outside weather and temperature changes. 
  4. Install thermostats in the most-used room in each zone. Avoid hallways, where a thermostat won't reflect the true temperature of any room.
  5. Don't put rooms with radically different heat loads into the same zone.  Rooms with conflicting solar or mechanically-generated heat loads on the same zone will not produce a comfortable home. A west-facing room with lots of afternoon sun, for instance, won't have the same cooling or heating needs as a room on the eastern side, so it shouldn't be in the same zone. 
  6. Install at least two registers in each zone to stabilize airflow and compensate if the other is temporarily blocked by a misplaced area rug or too-long drapes.

Remember, a cookie-cutter approach to designing a zoning system just won't do. Make sure the contractor you choose takes these factors into consideration when mapping out your zoning system
