While your home’s central air conditioner plays the most important role in maintaining cool comfortable air inside the home, there are several types of fans that each play an important role in keeping the air cool and healthy. The four main types of fans are:
Whole-House Fans
This type of fan is designed to circulate air throughout a home’s ductwork. It is sometimes confused with an attic ventilator fan (see below), which exhausts hot air from the attic to the outside through an opening in the roof. In some cases, a whole-house fan can take the place of a home’s air conditioning system by circulating air during times of the year when it’s not too hot, particularly when combined with ceiling fans.
Bathroom Exhaust Fans
A bathroom exhaust fan is designed to remove stale, humid air from bathrooms, laundry rooms, and other enclosed spaces with high humidity. They improve air quality and reduce the likelihood of mold and mildew growth. When installing an exhaust fan, it’s important to ensure that the fan is ducted to the exterior of the house and not just into an attic.
Attic Fans
Also called an attic ventilator, attic fans regulate the heat level of a home’s attic by exhausting hot air. They are usually controlled by a thermostat that automatically turns the fan off and on, or less frequently by a manual switch. An attic fan can be gable-mounted or roof-mounted.
Ceiling Fans
Ceiling fans are a popular choice for improving airflow in rooms, as well as serving as lighting fixtures and enhancing room decor. While a ceiling fan doesn’t actually lower the temperature, it circulates the conditioned air where it’s needed most and provides evaporative cooling.
