Central System vs Zoned System

There are two ways to install a QuietCool whole house fan system, either centrally located, or zoned in multiple rooms.

Centrally Located System

A centrally located system is a single whole house fan system, installed in a central location in the home.  A single system would typically be installed in the middle of a single story home, or at the top of the stairs in a two-story home (usually somewhere in the hallway).  A centrally located QuietCool system will effectively and efficiently ventilate an entire home, but does not offer the homeowner the luxury of running specific fans in specific areas.

Zoned System

Zoned systems include one fan centrally located, but also have other whole house fans conveniently located. Multi-fan zoned systems give the end user maximum control over their ventilation and cooling needs. To size a zoned system, the combined CFM of all fans need to add up to the total CFM requirements.

For example, for a 2400 square foot home, 4800 CFM would be required. A central system would only utilize a Trident Pro 4.8 centrally located. A zoned system could use a Trident Pro 3.3 centrally located and a Trident Pro 2.5 in the master bedroom. All zoned fans can be turned on simultaneously when the entire home needs to be cooled. This allows the homeowner to cool areas of their choosing once the house has been cooled.

Remember, if it doesn’t say QuietCool, it’s just another fan.
