An Attic Fans Inspection is conducted while performing an attic inspection, to ensure the house is properly ventilated. A fan in the attic is a desirable feature in a home, so if you don’t have one you might consider installing one. Because of trapped air, the attic area can reach temperatures as high as 150 degrees F on a hot summer day. Installing an attic fan that is thermostatically controlled will considerably reduce the heat load on the building. Generally, the thermostat is set to activate when the attic temperature is about 100 degrees F.Attic Fans Inspection – Thermostat and Humidistat Controls
In addition to thermostatic control, some attic fans also have a humidistat control, which turns the fan on and off whenever the relative humidity is too high in the attic, regardless of temperature. Regarding air conditioning, the attic fan provides two additional benefits. As the attic fan reduces the heat load on the building, air conditioning units will require less electrical energy. Moreover, if you have a central air conditioning blower coil located in the attic, the unit will operate more efficiently at lower surrounding temperatures.
During the warm days of summer, the attic fan should normally be operating. If it is not, the unit may be malfunctioning or the thermostat may e improperly set. On many units, the thermostat is exposed and can be manually adjusted, but if it is factory set and not accessible, the unit will require professional maintenance. To avoid such expenses, perform an Attic Fans Inspection regularly.
