How are attic fans controlled in Donora?
An attic fan is usually controlled by a humidistat or thermal switch. This switch will only allow your attic fan to operate if the temperature rises more than 90 degrees F. This feature will extend the attic fan's motor life and will reduce the loss of heat during winter. However, it will not let the fan reduce the buildup of moisture in the attic all the time and can't stop ice dams over winter.
Is it ok to have too much ventilation in the Donora attic?
Definitely. Many factors should be considered to determine the amount of ventilation that your attic needs. But technically, the more ventilation your attic has, the better. The more fresh air is brought into your attic, and as the turnover of air increases significantly, the temperature in your attic will begin to match that of the outside air temperature. That, in turn, will reduce the heat transfer within your home. More airflow in your attic will help increase the cooling performance of the attic fans.
Are these attic fans in Donora very loud when operating?
No. You won't even hear the attic fans while they are running. The blades used in attic fans are usually designed for quieter operation.
