General Information about attic fans

Many people install attic fans in their home because they reduce the temperature of the air in your attic thereby keeping your home cooler during the hot months.

The attic fan is controlled by a thermostat. The usual recommended temperature for the thermostat to be set is 95F. Remember this would be the setting based on one using the space but keeping it cool enough to cool the overall temperature of the home and is thought to help preserve the life of roofing as well. When the temperature at the attic goes over 95F, the attic fan will start working, when the temperature goes beneath 95F it will stop working.

A humidistat can also be installed. It will help reduce the moisture in the summer and in the winter time. In the summertime the attic is hot and humid and in the winter time humidity from cooking, bathing, heat travels up to the attic and condensation accumulates in the attic. In addition, humidity can cause mold and wood damage that can affect our pulmonary system for example by exacerbating asthma, emphysema and causing flu, and common colds.

Our electricians install new attic fans, replace the motors, or replace the complete existing attic fan depending on their condition. They also install thermostats and the humidistats to control the attic fans.

Solar Attic Fans

U.S. Sunlight’s line of Solar Attic Fans provide the active ventilation your attic needs to reduce the heat build-up that could reach temperatures of 160F and higher. 43% of air conditioning design load is based on high attic temperatures and it’s this heat build-up that can overheat your air conditioning ductwork and raise the temperatures in your home’s living spaces.

 

The Solar Attic Fan pays for itself quickly with a reduced strain on your air conditioner, a 30% Federal Tax Credit and extending your roof life up to 10%. Adding a Solar Attic Fan provides active circulation and improved airflow to effectively ventilate your attic space and lower the temperature – giving you a cooler house and a more comfortable living environment!

Cool Your House in the Summer

During the peak summer months, your attic’s temperature can rise to 160° or more. This heat build-up can then raise the temperature inside your home and increase the amount of electricity used by air conditioners and other cooling equipment.  Installing a Solar Attic Fan will help remove the heat build-up in your attic and bring your attic’s temperature down closer to the ambient outside temperature.

 

The reduction in attic temperature will also benefit the homeowner by preserving and extending the life of the roofing and attic construction materials. Additionally, hot air in your attic can then heat the metal exterior of your HVAC ductwork and consequently heat the air passing through it, causing your air conditioner to work even harder.

Protect your house in the winter

In the winter, a typical attic absorbs up to 28 gallons or more of water from the warm, moist air rising from the inside of your home and collides with the cold underside of the roof. U.S. Sunlight Solar Attic Fans provide the air circulation which prevents the moist air from condensing on the surface, keeping your attic drier and helping to prevent mold and mildew from forming inside your attic and from ice damming on your roof.

 

Moisture in the attic can also lead to other troublesome problems. Humidity can cause saturated insulation, sheetrock pops and truss uplifts, which can cause damage and cracks to the drywall inside your house.

Benefits of an Attic Fan

Improve Your Home’s Energy Efficiency with a Solar Attic Fan

A well-ventilated attic will help reduce your energy costs several ways. Improved air circulation in the summer months will help remove hot air and reduce the temperature of your attic. This will keep the hot, stagnant attic air from seeping through into your living area. It will also help reduce the surface temperature of your attic floor and your interior ceilings.   The reduced temperature in your attic will also assist your air conditioner by keeping the ductwork and the air inside cooler. The resulting effect will be cooler air flowing through your HVAC system and reduced strain on your a/c unit.

Extend the Life of Your Roof

When your attic heats up, the roofing underlayment beneath your roof shingles can also heat up and, over time, become brittle and ineffective. By lowering your attic temperature you can extend the life of your roof and save the expense of repairs and replacement.

Remove Moisture and Reduce Harmful Mold

During the winter months, warm, moist air from inside your home rises into the attic and collides with the colder underside of the roof. Proper attic ventilation can help remove the moisture and condensation that can build from this event.   The Solar Powered Attic Fan and the All Purpose Ventilator are great ways to effectively ventilate your attic while saving money on electricity.

Prevent Ice Damaging

If you live in an area that has snow, the warmer attic air will heat the roof and melt the snow which drips to the eaves where it can refreeze as ice and form ice-dams under the eaves. These ice-dams will cause water to work back up under the shingles into the attic and down to the ceiling.
