QC Oklahoma can design a custom Whole House System for your home. There are two types of systems: Zoned and Central. When designing a system there are several considerations, such as lifestyle, level of the system: Superior, Advanced, Basic, Sizing, and Affordability. This does not have to be done all at once.
A centrally installed system is a single fan system that is installed in a central location in the home, as the name implies. A single system would typically be installed at the midpoint of a single-story home, or at the top of the stairs in a two-story home. A single QuietCool system will nicely ventilate an entire home but lacks the individual room control that a zoned system offers.
A multi-fan zoned system gives the homeowner maximum control over their ventilation and cooling needs. When sizing a zoned system, the combined CFM of all zoned units (not each individual fan) needs to add up to the total CFM requirements. All zoned fans can be turned on simultaneously when the entire home needs to be cooled. A zoned system also allows individual bedroom control, however, and allows for more specific airflow control.
There are two other considerations to take into account when sizing a whole house fan system:
Location: If located in a coastal region where the climate is cooler, a good system should work great. If located in a desert region where the climate is very hot during the day but cooler during the night, the best system would make the most sense.
Ceiling Height: If the ceilings in the home are taller than 8 feet, be sure to size the system a little bit larger to account for the increased air volume inside of the home.
After determining the total amount of airflow needed, it is time to select a system. We offer three levels of systems:
Superior System: Zoned Cooling with multiple Quiet Cool Energy Saver or Stealth Pro fans in the system.
Advanced System: Zoned Cooling with multiple Quiet Cool Classic or Trident Pro fans in the system.
Basic System: Central Cooling with a single Quiet Cool fan located centrally in the home. These fans can be from either the Classic or Professional Series.
We use a general formula of either 2, 2.5, or 3 CFM, or “Cubic Feet per Minute”, per square foot of living space. 2 CFM would provide a good system, 2.5 CFM would provide a better system, and 3 CFM would provide the best system.
To calculate how much CFM you need in your home, ask a QC Oklahoma represented:
NOTE: For every 750 CFM the Manufactory recommends 1 square foot of free flow air opening from your attic.
You don’t have to do it all at once.
You can always add on.
Example 1:
Single story house 2700 to 3500 sq. ft., 3-bedroom couple lives there with two kids, sleeps with master bedroom door closed.
Superior System: Stealth pro 7.0 whole house fan centrally located. One Stealth pro 2.2 fan in master bedroom and Stealth pro 1.5 fan in each of the other bedrooms and solar roof mounted roof fan or solar Attic Fan. Open air flow openings expanded to 14.68sq ft.
Advanced System: Stealth pro 6.0 whole house fan centrally located. One Stealth pro 2.2 fan in master bedroom solar roof mounted roof fan. Open air flow openings expanded to 10.85ft.
Basic System: Stealth pro 6.0 whole house fan centrally located. Open air flow openings expanded to 7.85.
Example 2:
Two story house 2400sq. ft., 4-bedroom couple lives alone sleeps with master bedroom door closed.
Superior System: Stealth pro 6.0 whole house fan centrally located. One Stealth pro 2.2 fan in master bedroom and Stealth pro 1.5 fan in each of the other bedrooms and solar roof mounted roof fan or solar Attic Fan. Open air flow openings expanded to 13.21 ft.
Advanced System: Stealth pro 6.0 whole house fan centrally located. One Stealth pro 2.2 fan in master bedroom solar roof mounted roof fan. Open air flow openings expanded to 10.85 ft.
Basic System: Stealth pro 5.5 whole house fan centrally located. Open air flow openings expanded to 6.725 ft.
