Your duct system has a direct and significant
effect on many things, to include:
Equipment size & efficiency of the system
Operating cost
Envelope infiltration (bringing in unwanted outside air)
Indoor air quality
Ambient noise & nuisance drafts
Occupant comfort (cold & hot rooms throughout your home)
Therefore, the duct system must be
carefully designed and properly installed in order to maximize the benefits of
an efficient duct layout and the associated heating/cooling equipment.
A properly designed duct system will balance the 'correct airflow' to every room in your house. This will minimize nuisance drafts, hot & cold rooms and will reduce duct/air noises when the system is on.
