Venting plays a very significant role in the performance of QuietCool fans. QuietCool recommends a minimum of 1 SQ. FT. of venting for every 750 CFM in the QuietCool system. If an attic has at least 1:750 attic venting, the QuietCool system will operate efficiently and effectively. If an attic has less than 1:750 attic venting, the system may not operate as efficiently, or effectively, as it could with 1:750 attic venting. But don’t worry, the system will still operate if there is not enough venting.


Insufficient venting is a very simple problem to fix. We can add extra venting to most homes simply and easily. The most common types of venting is shown in the chart below.
