                              According to the American Lung Association, homes are like lungs, they need to breathe to make sure that fresh air comes in and dirty air goes out. To keep your home safe you have to introduce fresh, outdoor air to dilute these indoor pollutants. Turning on your QuietCool Whole House Fan means you no longer have to recycle your air, you can let your home breathe.

                              Don’t have a conventional attic space above your living area? Utilize a Vertical Adapter and cool your home with a side attic. These adapters were created as some homes do not have attics above their living area. Some homes throughout the country have a side attic against their wall and only enough attic space for our Whole House Fans in this area. When this is the case, these homes can use a Vertical Adapter so our R5 Damper Doors can still operate successfully while offering the entire home cooling and comfort.

                              WHOLE HOUSE FAN SIZING FORMULA

                              We utilize a standard formula of 2, 2,5, or 3 CFM per square foot of living area. 2 CFM would be sufficient for a good system, 2.5 CFM for a better system, and 3 CFM for the best system. Utilize the calculator on this page to determine the amount of CFM required for your home. This formula will always work, regardless of the size of the home, and remember that the greater the airflow, the better.

                              Considerations for Size
                              When sizing a whole-house fan system, there are two additional aspects to keep in mind:

                              In a coastal area where the environment is colder, a well-designed system should be able to function. There are a number of factors to consider when deciding on the ideal system for a desert environment where temperatures can fluctuate greatly throughout the day and night.

                              If the ceilings in your home are higher than 8 feet, you’ll need to size the system a little larger to account for the increased airflow.

                              Allows the homeowner to have complete control over their ventilation and cooling needs with a multi-zoned system. A zoned system’s total CFM requirements are met by adding the cumulative CFM of all zoned units, not by adding the CFM of each zoned fan individually. Zoned fans can be used simultaneously to cool a large area of a residence. However, a zoned system provides for more precise airflow management in each individual bedroom.
