How Loud are Whole House Fans?

A whole house fan is an energy-efficient alternative to an air-conditioner offering a fantastic way to cool your home. Modern whole house fans, particular Quiet Cool whole house fans, are designed to be quieter than their older model predecessors.

How does a whole house fan work?
A whole house fan is typically installed in the central hallway ceiling. They work by drawing in the fresh outdoor air through the windows while the warm indoor air is pushed out through the exhaust and the vents in the roof.

Factors that Affect the Noise Level of the Whole House Fans
While a whole house fan can be an energy-efficient way to control your home temperature it does have some drawbacks. The fan can be noisy especially if it is not installed properly.

Factors that affect the noise level of a whole house fan include:

● The installation quality: Poor installation can cause a whole house fan to vibrate and make extra noise.

● The fan age: The older fans used industrial inexpensive motors and were known to make loud noises.

● The fan size: Larger whole house fans with more blades tend to make a louder noise.

The Noise Level in a Whole House Fan by Decibels
Unlike the older models, the noise levels of the newer whole house fans are almost silent to moderately loud, depending on how they are installed and their model.

● Advanced whole house fans: The decibel levels of advanced whole house fans range from 40 to 52 decibels, similar to that of a standard AC unit in your home. The quietness of the fans was achieved by physically separating the motor housing away from the air register located at the ceiling level.

● Quietcool QC CL-1500 whole house fans: It has a sound level of 37.4 decibels compared to a whisper at 30 decibels and a babbling brook at 40 decibels.

How to reduce the noise level of a whole house fan?
You can enjoy a well-ventilated house in a quieter setting by choosing one of the newer models like The QuietCool QC CL-3100 RF Whole House Fan.

It is a ducted inline whole house fan that operates quietly. Unlike the older fans, the newer model is suspended in the attic from the rafter which helps cut off the noise. The whole house fan also comes with an acoustically insulated flex duct that keeps the fan’s noise level to a minimum.

Outstanding energy efficiency.
