Running an attic fan isn t just running any other fan of your home.

After the attic fan has been in use for some time it may develop problems. Quietcool attic fans work almost everywhere almost anytime. Knowing how to troubleshoot common problems that could befall your fan will help you make simple repairs. An attic fan vents the attic of hot air through a set of shutters or louvers.

The attic fan works by removing the superheated air from your attic so the air in your entire home can circulate and cool down. If the shutters do not open back pressure will form in the attic forcing superheated air into the home living space making it uncomfortable and causing the air. The attic fan tends to makes a humming noise when it has a few blades and is running at a high speed setting. An attic fan is a great way to keep your home cool during the hot summer months.

These gravity operated exhaust shutters can be used with direct or belt driven exhaust fans and can help prevent air backflow when the fan is off. The shutters automatically open when the fan comes on to allow the flowing air to escape to the outside. During the summer an attic can be 40 to 50 hotter than the outside temperature which in turn heats up the house very quickly. In order to get rid of the hum you need to either operate the fan at a low speed or replace the fan with a new one that has more blades.
