Attic fans are an energy-efficient system that helps your attic cool down as it absorbs the heat from your roof. They also prevent humidity from damaging your roofing system or molds during the cold and rainy seasons. 

Learn about the ins and outs of attic fans and why you may need one.

How Do I Choose An Attic Fan?

Attic Fan Maintenance

Unless you convert your attic as a bedroom or an office, you will probably only visit it once or twice a year. Thus, an efficient yet low-maintenance attic fan is necessary. 

Fortunately, most attic fans only require cleaning of fan blades and shutters once a year. Another advantage is some attic fans have lifetime lubricated motors. Finally, a quick check of the circuit breaker and thermostat is necessary to avoid malfunction.

Attic Fan Safety

Aside from maintenance, the safety of your attic fan is crucial. Issues may arise depending on which type of fan you are using and the condition of your attic. 

Some attics have furnaces or generators to save space, which may not bode well with an attic fan as it can push gas into your homes instead. In case of fire, the fan may also spread fire faster throughout the house.

One way to prevent a disaster is to make sure you have a well-ventilated attic. You should also check for automatic control features to help regulate your attic fan. Consult a professional when in doubt.

Attic Fan Materials

Good quality fans require durable materials that can withstand heat, cold, or moisture. Avoid delicate materials like plastic that may become brittle in the winter. Metal fans are more durable and long-lasting no matter the season. 

Different Attic Ventilation Types

Whole House Fans

If you need something to cool your house rapidly, then whole house fans can do just that. The air exchange process allows the fan to push out hot air from indoors and brings in cool air from the outside in minutes. They also remove allergens, pollen, and other pollutants for healthier air quality.

Usually mounted between the attic and the living space, only install this fan in open and vented attics so the air can go out. Otherwise, moisture can get trapped and promote mold growth.

Keep your whole house fan on in the morning or evening for a cooler breeze. Check with a professional whether you need an insulated door whole house fan, standard whole house fan, or a ducted whole house fan.

Attic Vent Fans

Unlike whole house fans, an attic vent pushes out warm air only from your attic space. After which, the vents pull in cold and dry air from the outside and your soffits. Doing so allows your roof to maintain a cool temperature, so the snow will not melt on warm spots resulting in ice dams. 

Your attic vents need not be on 24/7. Automatic operators like a thermostat, timer, or humidistat regulate your attic vents and help reduce your electricity bill. For optimum performance, make sure that your attic has no holes.

Best Attic Fans

There are two mounting types of attic fans: gable mount and roof mount. 

As the name suggests, you can install gable-mounted fans on the gable end walls of your attic. This type of fan allows you to have only two ventilators, which works for an average attic space. 

Roof-mounted attic fans require installation on the roof ridge. Unlike gable mounts, roof mount attic fans take less time to install and allow multiple attic fans for more space coverage.

Below are the best attic fan models in terms of quality, performance, and budget.
